2 Fire fighting System Operation Specification
2.1 Automatic Fire Alarm System
2.1.1 System Composition
This system is composed of detect part, monitor part and linkage part.
2.1.1.1 Detection
The detection part is mainly composed of intelligent smoke detector, intelligent thermal
detector, explosion-proof thermal detector, switching linear thermal detector, type thermal
detector, analog linear thermal detector and manual alarm button. Smoke detector and thermal
detector are mainly used for housing space detection; manual alarm button is mainly used at
corridors, fire control lobby and other positions where the fire can be found by man, and used
for activating the alarm or linkage equipment; analog linear thermal detector is mainly used in
fuel pump room, main fuel tank, makeup fuel tank, middle layer oil pipelines, and other
important positions where typical detector can not be used; switching linear thermal detector is
mainly used at cable tunnels, cable trays and other positions.
2.1.1.2 Monitoring part
The monitoring part is mainly used for data acquisition, curve sampling, data analysis and
result judgment, consisting of central intelligent processor, and can effectively eliminate
interference and accurately deal with the feedback signal.
2.1.1.3 Linkage part
The linkage part is mainly used for implementing real fire extinguishing function. After the
control device receives an accurate alarm action signal, the linkage part will, according to the
linkage logic, implement fire extinguishing protection over the protected areas.
2.1.2 Working Principle
The fire alarm controller can directly receive two (smoke and temperature) types of fire
detectors’ alarm signals. When there is a fire at the detected position, the detectors will send
fire alarm signals to the controller, the corresponding fire light of the controller will light up
and send audible and visual alarm signals, and then the external audible and visual alarm will
start to work; if both types of detectors send fire signals to the controller, the audible alarm in
the controller will emit acoustic alarm signal, then the fire light on the display panel will flash,
and meanwhile, the second point of the clock display will stop flashing and instead display the

- 7 -
fire occurrence time, until the controller reset button is pressed down. After receiving alarm
signal, the controller will automatically send start signal to the fire extinguishing unit; when the
controller receives the blow return signal, the discharge light on the panel will light up and
control the light-up of the discharge light in the protection area.
2.1.3 Operating Instructions
2.1.3.1 Automatic fire alarm function: If the controller determines there is indeed a potential fire, the
controller will light on the fire indicator light, send fire alarm, display fire alarm code address
on the display tube, and display the fire alarm code address, detailed position, detector type
and fire alarm time on the LCD screen. If there are multiple fire alarms simultaneously, the
LCD screen will display the total number of fire alarms, and also display the detailed
positions of the first alarm and the latest alarm, the type of detector and the fire alarm time.
All alarm information can be viewed via the fire alarm view. There is a plane fire alarm
drawing on the CRT color display system and after the device acts, corresponding alarm layer
will automatically jump out and then the alarm point will flash. When the "fire" light, etc. on
the panel light on, the alarm layer will display red and display fire alarm code address,
detailed position, detector type and fire alarm time.
2.1.3.2 Linkage control function: manual / automatic conversion and manual / automatic fire linkage
control can be realized under set menu. When the controller sends a fire alarm signal, if in
automatic mode, the controller will make the device act according to the set linkage
relationship, and display the name of the acting device and the total number of actions on the
LCD screen. At this moment, all linkage information such as address code, detailed position,
device status (successful action, failed action, wait for command, live action), and action time
can be viewed via the linkage view function. If in manual mode, the controller will not issue
control instructions after sending the alarm information, and the staff on duty need to confirm
the occurrence of a fire. If it is necessary to start fire linkage control, press the "fire
confirmation" button to start automatic fire linkage control according to the set linkage logic.
There are such buttons (fan start / stop button, fire pump start / stop button, etc.) set on the
panel that can directly start devices. These buttons can be manually manipulated to control
these devices.
2.1.3.3 If the controller identifies a fault, it will light on the fault indicator light, emit fault alarm
sound for 10 seconds, and then emit fault alarm indicating sound once every one minute. The
fault alarm may be stopped via silencing operation. After the fault cause is identified, the fault

- 8 -
may be excluded.
The controller has reset function. By resetting, the controller can eliminate fire alarm or
linkage action information. If it is not a false alarm, there will be re-alarm after the resetting.
In this case, it is necessary to go to the scene to verify whether there is a fire or any other
unforeseen circumstance.
Never press the button continuously during operation, so as to avoid damaging the system.
2.2 Automatic Sprinkler System
2.2.1 System Components
The system consists of sprinkler pipe water supply, pipeline control valves, deluge valves,
water motor alarm, pressure switches, solenoid valves, water flow indicators, open or closed
sprinklers and pipelines.
Deluge valve device is widely used in deluge system, pre-action system, water curtain system
and water mist system. Except for pre-action system, all other systems are equipped with
open sprinklers on the side pipelines. The opening of deluge valve device is controlled by site
fire detection system. When there is a fire breaking out somewhere in protected areas, the
environmental temperature will rise, and the fire detection system will act and open the
deluge valve, so that a lot of water will eject from the open sprinklers. The fire detection
system will also send alarm signal to control the fire. In emergency situations, the deluge
valve may be opened directly via manual valve operation.
2.2.3 Operating Instructions
2.2.3.1 Electrical control deluge valve extinguishing system: the system is composed of deluge valve
device, solenoid valve, open sprinklers and electrical detection devices. Within this system,
electrical detection devices are distributed at key locations throughout the fire zone, forming
monitoring network and connected to the electrical control box. Under normal circumstances,
the solenoid valves (power consumption 50W, voltage DC24V) installed on the outlet piping
of the diaphragm chamber are under off state, to hold the pressure inside the diaphragm
chamber. When the electrical control box receives a fire signal sent from the electronic
detection unit, the fire signal will be processed and send start signal to the electronic valve to

- 9 -
open the solenoid valve, so that the pressure inside the diaphragm chamber will decrease,
thereby the deluge value is opened, and then the water will eject from the open sprinklers to
the entire protection zone. Besides, the Water motor alarm and pressure switch will act and
start the fire pumps to implement fire-fighting function. After the fire is put out, open the
water-discharge residual pressure valve, the residual water at rear part of the deluge valve will
be exhausted, and then the deluge valve will be automatically closed. Now, close the
water-discharge residual pressure valve and the manual reset valve, so that the system will
enter into standby mode. Meanwhile, the residual water in the pipelines must be discharged
completely from the drainage ditch, so as to protect the sprinkler pipes.
2.2.3.2 Wet control deluge valve extinguishing system: the system is composed of deluge valve
device, open sprinkler, closed probe sprinkler (glass ball sprinkler, fusible sprinkler), etc.
Within this system, closed probe sprinklers are mounted on the wet control pipelines at key
locations throughout the fire zone. Such wet control pipelines are connected to the outlet of
the deluge valve diaphragm chamber. When a fire occurs, the probe sprinkler will turn on the
switch to spray water, the pressure in the control system pipelines will decrease rapidly, the
pressure in the diaphragm chamber will decrease since the throttle plate at the water supply
can not sustain the original pressure due to the lack of adequate amount of water, therefore,
the deluge valve will be opened under water supply pressure, the water will flow onto the side
of the system and eject from the open sprinkler. Besides, the Water motor alarm and pressure
switch will act and start the fire pumps to implement fire-fighting function (the control
system must be mounted at non-freezing place). After the fire is put out, open the
water-discharge residual pressure valve, the residual water at rear part of the deluge valve will
be exhausted, and then the deluge valve will be automatically closed. Now, close the
water-discharge residual pressure valve and the manual reset valve, so that the system will
2.2.3.3 Dry control deluge valve extinguishing system: the system is composed of deluge valve
device, open sprinkler, closed probe sprinkler (glass ball sprinkler, fusible sprinkler), air
compressor, solenoid valve, etc. Within this system, dry control pipes will be arranged at key
positions in the protected zone, and there will be closed probe sprinklers connected to deluge
valve diaphragm chamber and compressed air source. When a fire occurs, the closed probe
sprinkler will be turned on, the air pressure in the control system pipelines will decrease
rapidly, the pressure in the diaphragm chamber will decrease, therefore, the deluge valve will

- 10 -
be opened under water supply pressure, the water will flow onto the side of the system and
eject from the open sprinkler to the protected zone. Besides, the Water motor alarm and
pressure switch will act and start the fire pumps to implement fire-fighting function. The
pressure in the control pipe can be controlled by a solenoid valve, and the control theory is
same as that of electrical control deluge valve extinguishing system. After the fire is put out,
open the water-discharge residual pressure valve, the residual water at rear part of the deluge
valve will be exhausted, and then the deluge valve will be automatically closed. Now, close
the water-discharge residual pressure valve and the manual reset valve, so that the system will
2.2.3.4 Manual control: manual control is achieved by setting a manual valve in the outlet pipe in the
deluge valve diaphragm chamber, and it is generally used in conjunction with the above three
control systems. When staff on duty identifies a fire, he can open the cover of the manual
control device and open the manual value in the box to discharge water, so as to reduce the
water pressure in the diaphragm chamber. Therefore, the force that acts on the tumbler
through piston and ejector will reduce, the valve flap components will trip, the system water
supply will open the valve flap components and the open sprinkler will spray water. Besides,
the Water motor alarm and pressure switch will act and start the fire pumps to implement
fire-fighting function. After the fire is put out, open the water-discharge residual pressure
valve, the residual water at rear part of the deluge valve will be exhausted, and then the
deluge valve will be automatically closed. Now, close the water-discharge residual pressure
valve and the manual reset valve, so that the system will enter into standby mode. Meanwhile,
the residual water in the pipelines must be discharged completely from the drainage ditch, so
as to protect the sprinkler pipes.
2.3 Foam Extinguishing System
2.3.1 System Components
Foam extinguishing system is composed of fire water system, pipeline control valve, foam
concentrate storage tank, proportioning mixer, foam generator, foam hydrant, foam nozzle,
pipeline, etc.

- 11 -
When part of the pressure water enters into the proportioning mixer and then enters into the
storage tank water chamber through pipelines, squeeze the rubber diaphragm to extrude the foam
liquid in the diaphragm out through the suction pipe and mix with water to form foam mixture,
and then spray foam through air foam generator or spray device to fight the fire.
2.3.3 Operation
2.3.3.1 When the fire pump is started and there is pressure water in the pipe, firstly open the inlet
valve, the outlet valve and the water inlet valve.
2.3.3.2 Regulate the opening of the outlet valve of the system, until the pressure gauge displays the
rated working pressure of foam proportioning mixture and stabilize at a certain value.
2.3.3.3 When there is pressure water in the storage tank and the pressure rises to the working
pressure, open the liquid outlet valve, then the foam proportioning mixture will
automatically regulate to 6% (or 3%) proportion, and output foam mixture to the system.
2.3.3.4 When the fluid supply stops, firstly stop the liquid drain valve (to prevent pressure water
intrusion and in-flow into foam rubber bag) and then close the other valves, and also stop
the pump to stop working.
2.3.3.5 Method for initial perfusion of foam liquid:
a Close the liquid drain valve, and open water chamber gas outlet valve, gas drain valve and
diaphragm gas drain valve.
b Open the flange cover of foam liquid filling, and use a hand pump to fill the rubber bag
with foam liquid.
c When the foam liquid overflows from the diaphragm gas drain valve, the foam liquid is
full.
2.3.3.6 When testing the water, open the water chamber gas outlet valve and inlet valve, and let
pressure water in. When there is water ejected from water chamber gas outlet valve, close
the valve and let the storage tank under standby state.
2.4 Gas Fire-extinguishing System
2.4.1 Overview
Gas turbine and power equipment adopt high pressure CO2 fire extinguishing system which is

- 12 -
provided by gas turbine supplier. The system includes high pressure CO2 storage tank (storage
pressure bit 57bar/20℃), pipes and nozzles.
2.4.2 Operation
2.4.2.1
Steel cylinders adopt hammer (Fig. 2 red circles) as the weighing system that will be hung on
the top of the shelf. (The hammers in 1st
zone are numbered WOSL151-WISL162 and
WISL115-WISL159, the hammers in 2nd
zone are numbered WISL251-WISL252 and
WISL260-WISL270). If the hammer falls, the fire protection cabinet will send a signal to
MARK VI to display C02 low pressure alarm. The reason why a hammer falls may be that the
CO2 gas is lost or the balance setting is incorrect. The indication about the fall of a hammer is
that, there is a laser beam emitted on the horizontal line of the low position of the hammer, and
there is laser signal rebounded and received. If a hammer falls, the laser will be blocked and the
receiver will send a signal, but sometimes what blocks the laser may be other debris, such as
leaves, etc.
。
Steel cylinders are connected by a flexible tube to the collection tube (Fig. 3 green part), and
there is a one-way valve fitted at each connection. On one side of the one-way valves of the two
steel cylinders in the quick-release cylinder group of each zone, there is a thin tube for providing
pneumatic pressure to control the opening of all steel cylinders in a zone.

- 13 -
2.4.2.2
At the end of the collection tube, there is a stop valve (1st
zone quick-release tube HV150,
slow-release tube HV199, 2nd
zone quick-release tube HV250, slow-release tube HV299) with a
position switch indicating the switch position (1st
zone quick-release switch ZSL33CL-1B,
slow-release switch ZSL33CL-1A; 2nd
zone quick-release switch ZSL33CL-2B, slow-release
switch ZSL33CL-2A). This switch position signal will be sent to the fire protection cabinet, so
that the fire protection cabinet will not issue CO2 release instruction, and thus ensure the
collection tube safety.

- 14 -
2.4.2.3
Pressure switch (1st
zone PSH 45CP-1, 2nd
zone PSH45CP-2; setting value 3bar) located at
slow-release collection tube will determine whether to release CO2, when electronically driven
(by crushing the glass box or thermal probe action) by CO2 release. When mechanically driven
(by operating the manual pull rod located at the CO2 cylinder), the pressure switch will release
CO2, send a signal to the fire protection cabinet and a signal to MARK IV to give the user a
warning signal, and then jump off the combustion engine. This switch is manual reset type.
When refilling the CO2 cylinder full, the operator may manually reset to start the combustion
engine. Regardless of manual or automatic release, the pressure switch will send to MARK VI
the alarm that CO2 releases in 1st

2.4.2.4
The ladder-shaped control lever (Figure 3 purple color) is linked with the valve rod extended
from each steel cylinder. When the control lever moves, the valve rod of each steel cylinder will
be moved, and then release gas to control the piston to pull, which can be controlled by driving
cylinder, or the piston may also be pulled manually.
2.4.2.5
The gas source to the driving cylinder to control piston movement is controlled by solenoid
valve (1st
zone 45CR-1B and FY152, 2nd
zone 45CR-21B and FY252), and the solenoid valve is
controlled by the fire protection cabinet.
a In the 1st
zone, there are three audible and visual alarms (SLI-1A, 1B, 1C, 2C) installed
outside of the unit, and two flash alarms (SL-1, 2) installed inside auxiliary machine room.

- 16 -
In 2nd
zone, there is an audible and visual alarm (SLI-3C).
b There is a hand breaking glass alarm (43CP-1/2/3/4) installed at the gate of the auxiliary
machine room and the turbine room respectively, and there is a hand breaking glass alarm
(43CP-5) installed in load room. After the alarm is broken, the CO2 release will be triggered.
2.4.3 Notes and Routine Maintenance
Flexible exhaust pipe: if the rubber exhaust pipe surface is aged, replace the pipe immediately
Surface varnish: If the paint on the surface of the steel cylinder peels off, repaint it as soon as
possible, so as to avoid the exposed surface suffering air corrosion
Laser transmitter: adopt blocking way to check whether the laser transmitter can work
normally
Manual pull rod: check the rusting degree of the metal twisted wire to prevent the snap or
stuck during action
Probe: If it does not work, check the connection circuit or replace the probe timely
Hammer fall: check the amount of gas in the steel cylinder, and correct the weighing settings.
Weighing equipment can not display the location of empty cylinder: correct the weighing
settings.
The exhaust time is too long: the nozzle may be clogged, remove the nozzle and clear the plug.
Solenoid valve: solenoid valve is exposed for a long time, so if it will not work for a long time,
be sure to prevent moving the solenoid valve cabinet.
While repairing any ancillary device of a steel cylinder, make sure the protective plug of the
steel cylinder is pulled out. Since CO2 is not in continuous use, it is a low-wear device. So, if
operated normally and subject to periodic maintenance, the system will be protected from
mechanical damage caused by accidental impact, and the system should be reliable in a

- 17 -
long-term.

3.1.4.4 Operation
Each FCM-1 module occupies one of the 159 valid module addresses on SLC circuit, and
responds to the periodic query on the control panel, to report its model and the circuit status
(open / normal / short). LED flashing indicates the module is communicating with the control
panel, and when there is an alarm, the LED is locked and will be normally on. Once receiving a
command from the control panel, FCM-1 will stop monitoring, and will, according to the correct
polarity, connect the external power supply with the load device. The disconnected monitoring
can prove to the control panel that the relay has been really turned on. The relay completely
isolates the external power supply and the communication circuit, therefore, the failure of the
external power supply will not affect other parts of the system.
Rotary switch can set a unique address for each module, and the address can be set before or
after installation. Built-in code will report module type to the control panel.
3.1.4.5 Maintenance
Module is intact and clean, with no loose wiring
①Use fire detector tester to send fire analog signal to the detector according to 1/10 of the total
volume every month. When the monitoring module receives the switch value closing signal, it
will send the signal through bus to the controller, and the controller will send sound and light
alarm signal.
②After a detector alarms, the alarm confirmation light can be activated
Complete one full-sample inspection once a year. In addition, after the monitoring module is
put into operation for two years, it should be cleaned once every three years, and response
threshold and other necessary functional tests should be conducted.

3.2 Automatic Water Sprinkler System
3.2.1 ZSFG Deluge Alarm Valve
3.2.1.1 Overview
ZSFG type deluge alarm valve device (hereinafter referred to as deluge valve device) is of
leveraged structure, and has mechanical anti-reset function. It is a product that passed the
national fixed fire extinguishing systems and fire retarding component quality supervision and
inspection center, and is in line with GB5135.5-2003 standard. The deluge valve device is
widely used in various types of open systems (open sprinklers on system side piping), such as
deluge system, water curtain system and water mist system. Deluge valve device opens valve
clacks under the force of water supply pressure, when the pressure in the diaphragm chamber is
reduced. Release of the pressure in the diaphragm chamber can adopt a variety of ways such as
electrical guide mode, wet guide mode and dry guide mode.
Electrical guide mode is controlled by a fire alarm system. When a fire breaks out, the fire
alarm system will send a control signal to open the solenoid valve, so that the pressure in the
diaphragm chamber will release, the deluge valve will open, and then a lot of water will eject
from open sprinklers. Meanwhile, a small amount of water will drive hydraulic alarm and
pressure switch through alarm pipes, to send alarm signals, for the aim of fire fighting and
alarming.
The device should be installed vertically. In frozen area, the deluge valve should be installed
in an environment with temperature above 4 ℃. In wet guide mode, the deluge valve system
should be used in an environment with temperature not less than 4 ℃ and not higher than 70 ℃.
The device can also combine with foam system to form a foam deluge extinguishing system
used for fighting explosive and dangerous flow liquid fire.

3.2.2 ZSFZ Wet Alarm Valve
3.2.2.1 Overview
Wet alarm valve device consists of wet alarm valve, hydraulic alarm, delayer, pressure switch,
pressure gauge, water drain valve, test valve, alarm test piping and other components.
Wet alarm valve is a kind of one-way valve that only allows water to flow into the wet system
and drive under regulated pressure the supporting components to alarm;
Delayer is applied to wet alarm valve device to prevent false alarms that are caused due to
water supply pressure fluctuations and alarm valve leakage;
Water motor alarm is an all-weather audible alarm device, which produces no strike spark
during working and can be used at explosion-proof sites. Water motor alarm is consisted of
aluminum alloy body, aluminum alloy impeller, aluminum alloy bell housing, aluminum alloy

- 35 -
sprinkler and copper alloy bushing, etc. The water motor alarm does not need maintenance and
its service life is long.
ZSFZ type wet alarm valve device, together with pressure switches, water flow indicator,
sprinklers, signal butterfly valves, end water-test equipment and spray pump, form ZS series wet
automatic sprinkler system. It is currently the most widely used automatic sprinkler system.
3.2.2.2 Working Priciple
The wet system pipe is filled with pressurized water, in a long-term standby working state,
and is applicable to 4℃ -70℃ ambient temperature (and only vertically mounted). When a fire
occurs within protected areas, environmental temperature will rise, the temperature-sensitive
element (glass ball) of sprinklers will break, and the sprinkler will output water to fight the fire.
Meanwhile the water flow indicator will act and direct the fire area, the wet alarm valve will
start the water supply to fight the fire, and a small amount of water will flow to the alarm pipe,
and drive water motor alarm and pressure switch. Then, the water motor alarm will emit
continuous alarm, and the pressure switch will act: start the spray pump, and the control center
will emit sound and light alarm.

3.2.3 ZST Glass Sprinkler Head
3.2.3.1 Overview
Glass ball sprinkler is a key component of automatic sprinkler system. Glass ball sprinkler is
used to detect fires and control or put out a fire through automatic sprinkler. ZST series glass
ball sprinkler is made of wrought copper alloy frame, glass ball, seals, etc., through German

- 37 -
imported assembly line, so it has stable and reliable performance, compact structure and shape.
3.2.3.2 Working principle
Glass ball filled with the organic solution with high thermal expansion coefficient is used as
heat sensitive component. Under room temperature, the glass ball housing can withstand a
certain force, to ensure the nozzle seal. When the ambient temperature rises, the organic solution
in the glass ball will expand and produce huge internal pressure, until the glass ball housing
breaks and thus open the nozzle to spray water.

3.2.5 ZSFU Preact Alarm Valve
3.2.5.1 Overview
Pre-action system is an automatic sprinkler system developed in recent years. Technically it
combines automatic fire detection and alarm system and automatic sprinkler system, to play the
role of double-protection over the protected object. Pre-action system is particularly suitable to
cold freezing or those important places which should be prevented from water stain or mistaken
spray, such as computer room, reference room, historical data and archives, etc. Usually, the
system side pipe is filled with gas, so has dry system characteristics. The system can meet the
automatic sprinkler needs under high temperature and cold conditions. Once a fire breaks out,
the temperature and smoke detectors installed in protected areas will firstly emit fire alarm
signal. After receiving alarm signal, the fire alarm controller will send command signal to open
deluge valve. If the fire continues to develop, closed sprinkler glass ball breaks and start to spray
water, the water pump will start automatically and meanwhile the water motor alarm will give

- 39 -
alarm, to achieve the purpose of fire fighting and control.
3.2.5.2 Working Priciple
Pre-action system is composed of deluge valve, check valve, signal butterfly valve,
connecting flanges and valves, pipes and accessories. Pre-action system combines automatic fire
detection and alarm system and automatic sprinkler system, to play the role of double-protection
over the protected object. The system side pipe is filled with gas when there is no fire, so the
system has dry system characteristics. Once a fire breaks out, the temperature and smoke
detectors installed in protected areas will firstly emit fire alarm signal. After receiving alarm
signal, the fire alarm controller will send command signal to open deluge valve. Before the
closed sprinkler is opened, fill the system side pipe with water to change the system into wet
system. Meanwhile, system pressure switch will act and connect the sound and light display box,
to display that the pipe is filled with water. At this time, if the fire continues to develop, closed
sprinkler glass ball breaks and start to spray water, the water pump will start automatically and
meanwhile the water motor alarm will give alarm.

3.3 Foam Extinguishing System
3.3.1 PQ8 Low-expansion Foam Fire Extinguishing Gun
3.3.1.1 Overview
Airfoam playpipe is a kind of portable fire extinguishing devices; it can produce and eject
airfoam effectively for fighting fires from small oil tanks, oil on floor, oil products and other oils.
It is also effective in fighting fires from such ordinary solid materials as wood.
3.3.1.2 Main Characteristic

- 41 -
Pressurized water from water from water hose goes into the airfoam playpipe body(8) through
the 65 mm hose coupling(9)(figure 1), when pressurized water passes through orifice d1, a
negative pressure (vacuum) is formed in the chamber between the play pipe body and nozzle (1),
This chamber is connected with suction pipe(5) by suction pipe connector(7). One end of the
suction pipe is put into an airfoam liquid drum to draw in airfoam liquid and the liquid is mixed
with water in the ratio of 6 to 94. When foam solution passes through orifice d2, it is diffused
and atomized immediately. As a result of that, another negative pressure is formed and a large
amount of air is taken in to mix with solution and produce airfoam. Going through the barrel, a
strong strong foam stream is formed and ejected out.
The airfoam playpipe is provided with an “on-and-off” switch, foam flow can be switched on
or off by turning the “on-and-off” handle (2).
Both airfoam playpipe type PQ 8 and type PQ 16 have bu-pass devices linked with the
“on-and-off” handle. When proportioner is to be used supply airfoam solution ,turn the
“on-and-off” switch to position “foam solution” on the indicator plate so that the by-pass is
opened to get a better airfoam flow. When suction pipe is to be used to draw air foam liquid, turn
the “on-and-off” swith to position “liquid sucking” on the indicator plate.
The airfoam playpipe is provided with a round handwheel (3) whith makes operation easier
and protects the air foam playpipe from damage.
On each of the airfoam playpipe, there is a name plate on which nomenclature and type of
product, serial number, date of manufacture and name of factory are shown.

- 42 -
3.3.1.4 Operation
After water has been supplied normally, move the “on-and-off” handle to turn on the
“on-and-off” switch and foam flow is ejected out immediately.(Inlet pressure for airfoam
playpipe must be adjusted to its standard working pressure 0.7MPa and make sure that the
“on-and-off” switch is turned on to the maximum, otherwise vacuum may be damaged and
liquid sucking may be affected seriously). When it is necessary to stop the form flow from
ejecting, just turn the “on-and-off” handle to position “off”, the foam flow is stopped at once.
In case suction pipe is to be used to draw airfoam liquid, suction pipe has to be fixed quickly
and checked to see if its seal is in a good condition. Then put one end of the suction pipe into the
airfoam liquid drum.
In case an airfoam proportioner is to be applied to supply airfoam solution, move the pointer
on the regulating valve of the proportioner to a number indicating the airfoam producing
capacity required in accordance with specification of the airfoam playpipe used.
For example, if it is required to apply one type PQ4 airfoam playpipe, move the pointer to
position “25” and if it is required to apply two types PQ4 airfoam playpipes or one type PQ8
airfoam playpipe, move the pointer to “50”
3.3.1.5 Maintenance
a Always keep the airform playpipe in a good condition. Inspection should be made after each
use to make sure that all parts are good, connectors are tightened and the rubber packings of
suction pipe and hose coupling are not damaged.
b Always keep the airfoam playpipe clean, After each use, the airfoam playpipe should be
washed with clean water. Adherent dirt in the suction pipe and nozzle must be cleaned away.
Then dry it and put it in a cool and dry place so as to prevent it from corroding.
3.3.2 PC Low- expansion Air Foam Generator
3.3.2.1 Overview
The air-foam generator is a kind of the equipment fixed on the oil tanks to produce and
discharge air-foam. When the foam solution supplied by a foam fire truck or a fixed pump is
going through the generator, air-foam is formed, thus it can put out fire of oil.

PC24 24
The foam-fire generator is mainly composed of housing assembly, foam discharging pipe
assembly, and guide plate assembly.
When foam solution passes through the nozzle of the generator, a diffused efflux is formed,
and there is a negative pressure around it as a result of that, large amount of air is drawn into,
and air-form produced. Having gone through the foam discharge pipes and guide plates the
air-foam is transported to the storage tank; it covers the burning liquid surface steadily by
dripping along the tank wall.
3.3.2.4 Operation
a The rated working pressure at the inlet of the air-foam generator is 0.5MPa. It can be used
within a pressure range from 0.3to0.5MPa as well, but the rate of the foam solution and the
air-foam will vary relevantly.
b In order to supply the air-foam liquid in proper ratio, it is very necessary to attach air-foam
proportioners like Type PH32 or PH64 to the water pump.
c Ordinary air-foam liquid with a density of 3%or6% is to be used in the generator.
d A sealing glass must be mounted at the outlet of the housing so as to prevent gases in tanks
storaging flammable liquid from leaking. There are breakable splitting lines on one side of
the glass which will break immediately as soon as the pressure of the foam solution reach
to 0.1 to 0.2 MPa. The side of the glass with the breakable splitting lines should be placed
in the direction of the outlet
e To make sure that foam will drip along the tank will, the guide plates must be mounted on
the inside wall of the storage tank, thus the foam can be over the burning liquid surface
steadily so as so raise the efficiency of fire-extinguishing.
f The bore diameter of the inlet pipe on the air-foam generator must be more than the size
given by D.
3.3.2.5 Maintenance
a The pipe line of the air-foam generator must be kept free wholly. And checks must be often
made to see if the pipe line is blocked and if the sealing glass is in good condition.
b To avoid and minimize pipe line damages caused by the deformation of tank wall, it is
necessary to put a metallic hose of the same diameter in the inlet pipe of the generator.

3.3.3 YPHNW-80/110Pressture Foam Proportioner
3.3.3.1 System Constitution
Composed of foam concentrate storage tank with a capsule, proportioning mixer, pipes, valves
and other components
When firefighting pressure water flows through the device, the proportioning mixer will shunt
it according to 6% proportion. 6% pressure water will enter into the interlayer of the foam
concentrate storage tank with a capsule, to squeeze the capsule, replace same amount of foam
concentrate, and mix with the remaining 94% pressure water to produce 6% foam mixture. The
foam mixture will then be output to foam production equipment, to produce air bubble for fire
fighting.
3.3.3.3 Operation
a Confirm that every valve and the proportioning mixer in the system are under standby state
(i.e.: each valve in the pipe is open; the foam concentrate storage tank in the proportioning
mixer is filled with medium water and foam liquid, the air in the storage tank and the
capsule are exhausted; each valve in the proportioning mixer is closed), open the fire pump
and proportional mixing device solenoid valve, and the system will then work.
b After confirming the fire is put out, close the proportional mixer’s solenoid valve. At this
time, the system begins spraying and cleaning the pipes. After the pipes are closed, close
the fire pump and the system will then close.
c Open the water drain valve to relieve the pressure in the foam concentrate storage tank, and
then close the pressure relief valve.
d Replace those damaged parts in the system, check the system, re-fill it with foam liquid
according to the filling process, and then the system will be under standby state again.
3.3.3.4 Maintenance
①Whether gauges, pipes and their accessories are damaged.
②Whether water supply source and water level indicating device are normal.
③Check the appearance of foam proportional mixer, and it should be intact.
①Conduct an action test of the solenoid valve, and the starting and closing should be
flexible.

- 45 -
②The manual function of each valve of the proportioning mixer should be flexible.
①Check whether the capsule is intact (open water drain valve, and if the water severely
discolors or produces a lot of foams, it proves that the capsule is broken and must be
replaced.)
②Check all devices, pipes and accessories in the system.
