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.
