2. Fire Protection ?
 Fire Protection means prevent the fire from becoming destructive.
 Reduce the impact of uncontrolled fire and Save lives and property.

3. Types of Fire Protection System
1. Wet Sprinkler System
2. Dry Sprinkler System
3. Preaction Sprinkler System
4. Deluge Sprinkler System

4. Wet Sprinkler System
 Pipe are always filled with water(supply
side and system side)
 Heat from fire opens a sprinkler head
 There is no delay in time that water is put
on fire quickly.
 Less maintenance required

5. Wet Sprinkler System
 Allow water flow only one direction.
 A clapper prevents water from re-entering
the water supply.
 Gauges are placed on both the side Main
Supply and System.
 Dry pipe systems installed where
temperature will freeze water in a wet pipe
system.
Wet Pipe Sprinkler Valve

6. Dry Sprinkler System
 Dry pipe systems installed where temperature will
freeze water in a wet pipe system.
 Pipe are always filled with water on supply side and
compressed air on system side
 The air pressure holds clapper valve, so that the water
can passed into system, unless the air pressure is lost.
 When a Fire releases a sprinkler head, the air is
released from the piping, and stops holding down the
valve that was holding the water back, and water is
released
 Heat from a fire opens a sprinkler head.
 Air pressure drops in the piping and opens a clapper
valve.

7. Deluge Sprinkler System
 Pipes are not filled with water or gas.
 All sprinkler heads are pre-opened.
 A signal from sensor and water valve get open. Then water fills
pipes and flow from all heads until shut off of fire.

8. Pre-Action Sprinkler System
 Used primarily to protect property
where water could severely damage
facilities or equipment's (Historical
items)
 Similar to dry pipe and Deluge system;
 Little or no air/gas pressure.
 Water does not flow to the sprinkler
heads until detector activates
