A fire alarm system is number of devices working together to detect and warn people through visual and audio appliances when smoke, fire, carbon monoxide or other emergencies are present. These alarms may be activated from smoke detectors, and heat detectors.
A Fire Alarm & Detection System is number of devices working together to detect and warn people through visual and audio appliances when smoke, fire, carbon monoxide or other emergencies are present. These alarms may be activated from smoke detectors, and heat detectors. Alarms can be either motorized bells or wall mountable sounders or horns. They can also be speaker strobes which sound an alarm, followed by a voice evacuation message which usually state in the lines of "Attention, Attention. A fire emergency has been reported, Please leave the building via the nearest exit. DO NOT use elevators!" They may also be activated via Manual fire alarm activation devices such as manual call points or pull stations.
A fire sprinkler system is an active fire protection mea sure, consisting of a water supply system, providing ad equate pressure and flow rate to a water distribution piping system, onto which fire sprinklers are connected.
Fire hose reel systems consist of pumps, pipes, water supply and hose reels located strategical ly in a building, ensuring proper coverage of water to combat a fire. The system is manually operated and activated by opening a valve enabling the water to flow into the hose that is typically 30 meters away. The system pressure loss will activate the pump ensuring adequate water flow and pressure to provide a water jet of typically a minimum of 10 meter from the nozzle.
Dry Riser System
Dry fire main water supply pipe installed in a building for fire-fighting purposes,
fitted with inlet connections at fire service access level and landing valves at
specified points, which is normally dry but is capable of being charged with water
usually by pumping from fire and rescue service appliances.
Wet Riser System
Wet fire main water supply pipe installed in a building for fire-fighting purposes
and permanently charged with water from a pressurized supply, and fitted with landing
valves at specified points.
A fire pump is a part of a fire sprinkler system's water supply and powered by electric, diesel or steam. The pump intake is either connected to the public un derground water supply piping, or a static water source (e.g., tank, reservoir, lake). The pump provides water flow at a higher pressure to the sprinkler system risers and hose standpipes. A fire pump is tested and listed for its use specifically for fire service by a third-party testing and listing agency, such as UL or FM Global. The main code that governs fire pump installations in North America is the National Fire Protection Association's NFPA 20 Standard for the Installation of Stationary Fire Pumps for Fire Protection.
