Fire Sprinkler System
WHAT IS A FIRE SPRINKLER SYSTEM?
A sprinkler system is an active fire protection
method, providing adequate pressure,
integrated system of piping, connected to a
water supply, with listed sprinklers that
automatically initiate water discharge over a
fire area. Where required, the sprinkler
system also includes a control valve and a
device for activating an alarm when the
system operates.
HOW DO FIRE SPRINKLERS WORK?
Fire sprinkler systems are triggered by
extreme heat and can quickly extinguish
a fire in the room where it started.
TYPES OF FIRE SPRINKLER SYSTEMS:-
Pre-action:- Pre-action fire sprinkler systems are filled with air and
water is allowed to pass through when the smoke alarm or detector
goes off.
Dry Pipe:- Dry pipe sprinklers are similar to pre-action systems as
they use pressurized air in the pipe which exits before water escapes.
Wet Pipe:- Wet pipe fire sprinklers constantly have water in them.
This allows for a quick reaction to a fire and is the most common type
of sprinkler installed in buildings.
Deluge:-These types of fire sprinkler systems also need a smoke or
heat detector like the pre-action system. A deluge system has open
nozzles that can be used when a hazard is present.
HOW IS FIRE SPRINKLER SYSTEM
INSTALLED?
Sprinklers are installed by specially trained contractors
who follow NFPA codes and standards and other local
requirements.
