Fire Alarm Systems
System Selection based on:
Building occupant safety Satisfy building codes or AHJ requirements Property protection First responder safety Environmental protection Combination of above
9/9/2013 22
Fire Detection
Spark/Ember Detectors Flame Detectors Combination Radiant Energy
UV IR
Smoke Detector
Ionization Photoelectric
Heat Detectors
Fixed Temperature Rate-of-Rise

Fire Suppression Systems
4 categories of sprinkler systems
Wet-Pipe Dry-Pipe Preaction Deluge
9/9/2013
28
Wet-Pipe System (Sprinklers)
System contains water under pressure at all times Series of closed sprinkler heads Heat activates sprinkler head Water discharged immediately from sprinkler head
9/9/2013
29
How do Wet-Pipe Systems/Sprinklers Work?
Sprinkler head
Water is released and deflected in a spray pattern
As temperature rises the bulb will shatter
9/9/2013
30
Dry-Pipe System
System contains air under pressure
Compressor on system keeps pressure up
Sprinkler heads hold the pressure Valve holds back water supply Valve opens when pressure falls below a predetermined level in the pipes Heat activates sprinkler head Water discharged immediately from sprinkler head
9/9/2013
31
How do Dry-Pipe Systems Work?
1. Heat Activated, sprinklers head opens
2.
Pressure Drop
3.
Valve Opens
4.
Water sent to all sprinkler heads
5.
9/9/2013
Water Discharges from activated head
32
Preaction System
System contains air under pressure
Compressor on system keeps pressure up
Water held back by preaction valve Supplemental detection Operation of detection system allows preaction valve to open and water fills system Water not discharged until fire has generated sufficient heat to activate a sprinkler head
9/9/2013
33
How do Pre-Action Systems Work?
1. Smoke Activated, opens primer in valve
2.
Pressure Drop
3.
Valve Opens
4.
Water sent to all sprinkler heads
5.
9/9/2013
Water Discharges from activated head
34
Deluge Systems
Deliver large quantities of water over a specified area in a short period of time Piping at atmospheric pressure Sprinkler heads are in open position Deluge valve keeps water back Supplemental detection activated deluge valve Water discharged from all heads immediately
9/9/2013
35
Sprinkler Flow Alarms
Switches to detect water flow
Fire alarm system activated when water flow detected
9/9/2013
36
Fire Pumps
Used when hydraulic demand exceeds public supply capacity Components
Pump and motor Controllers (fire pump and jockey pump) Jockey pump Water tank
9/9/2013
37
Water Supply
Standpipe System
Class I Intended for Fire Department use Class II Intended for trained occupants Class III Provided with 2 inch and 1 inch hose connections
Fire Department Connection

Construction and Containment
Buildings classified by 9 levels of fire resistant materials (e.g. walls, roofs, columns) High level Type I (High Rise)
Low Level Type V Non-Rated (Homes)

Examples of Construction & Containment
Closing fire doors Fire/Smoke dampers
Fire penetrations around pipes in rated walls

Know Your Building
Become familiar with:
Locations of sprinklers and standpipe Location of fire alarm devices Locations of exits and egress Emergency evacuation routes Do you have emergency power where located?

Conclusions
Codes drive facility fire and life safety requirements Know what codes apply to your operation Find out who is your AHJ Maintain fire and life safety systems at all times Always report non-operational fire systems to your appropriate department Be aware of fire hazards report as appropriate
