Photoelectric smoke detector principal
 Uses a photocell coupled with a specific light source.
 Basically smoke entering the smoke detector chamber disrupts the light beam
causing an alarm signal to be initiated
 More sensitive to smoldering fires Smoke detection with selectable sensitivity from
1.5 to 3.7 % per ft. obscuration. Temperature sensitivity rating 57oC
1: optical chamber
2: cover
3: case moulding
4: Photodiode (detector)
5: infrared LED

Operate on the principle that the temperature in a room will increase
faster from fire than from atmospheric temperature, Will initiate an
alarm when the rise in temp. exceeds 12-15° F (8.3- 11.1° C) per
minute.
Fixed temperature is independent of rate of raise sensing and set
point is 68° C

S.No PLANT AREA TYPE OF DETECTORS
1. Main control room, Computer
room, Electronic cubicle
room, panel room
Combination of -
Photo electric type smoke detector (AFC, BFC)
2. Battery rooms and chemically
corrosive areas.
Heat detector (Corrosion resistant, Rate of rise of
temperature heat detector with fixed temperature setting.
3. Office rooms / storage rooms,
Switchgear rooms in main
Plant and outlying areas
Multi sensor detector
4. Cable gallery Multi sensor detectors and Linear heat sensor running
above all HV and LV power cable trays. Unless the vertical
distance between cable tray is less than 500 mm in which case
alternate trays (in addition to the top and bottom trays). The
optical smoke detector and LHS detectors along with
necessary number of interface units in the cable gallery will be
cross zoned to actuate the water spray system

5. Coal Conveyors digital Linear heat sensor cable, infra red detectors.
water spray system is provided the LHS cable will be burnt
and short circuited to actuate the same
6. Dusty areas in coal handling
plants like crusher house
Flame proof manual call points.
7. Junction towers Flame proof heat detectors, flame proof manual call points
8. Hazardous plant areas such
as fuel oil / lube oil tanks
Probe type heat detector with fixed element and flame proof

CONTROL PANELS
MFAP (main fire alarm panel)
SFAP (Sub fire alarm panel)
RFAP (Repeater fire alarm panel)
CCAP (Control cum annunciation panel)
CFAP (Conventional fire alarm panel)

15. 15
ALARM SILENCE- It is programmed to silence the audible hooter at field and allow strobe light to continue
(strobes still flashing) until acknowledge the fire alarm.

16. 16
Fire Alarm Ack- acknowledges a Fire Alarm condition, logs the
acknowledge, silences the operator panel and all annunciator
tone alerts, and displays sequential alarm list

17. 17
SUPV ACK acknowledges system supervisory conditions, logs the
acknowledge, silences the operator panel and all annunciator tone alerts, and
displays sequential supervisory condition list

18. 18
SYSTEM TROUBLE ACK acknowledges system troubles, logs the
acknowledge, silences the operator panel and all annunciator tone alerts,
and displays sequential trouble list.

Manual Call Point (MCP)

31. 31
Some body PULL DOWN the Manual Call Point (MCP) leaver,
then alarm came Fire alarm panel, By using key only we
normalize this MCP. Once open the key then lever will settled in
normal position.

32. 32
First we press the ALARM SILENCE button in the panel, then
Alarm silence in progress.
Second we press the Fire acknowledge button in the panel, we
get the detailed alarm description

33. 33
Particular alarm silence LED illuminated in the panel

34. 34
After normalizing the MCP, Fire alarm is changed to normal alarm

35. 35
After normal alarms came press the SYSTEM REST button in the panel,
“system reset in progress”

36. 36
Normal alarms shows like this

37. 37
For viewing the alarms history
Press the menu then display this page

38. 38
By pressing the “next button” select the “Historical Logs”
display this page

39. 39
By pressing the “Alarm log view”, Alarm log will displayed, press “page
down” we get the previous alarms

40. 40
By pressing the “Trouble log view”, Trouble log will displayed,
press “page down” we get the previous troubles list
