Types of Fire Sprinkler Systems
Fire suppression systems, sprinklers, in New York City save lives and keep properties safe from catastrophe when a fire breaks out. We’ve become used to seeing the fire sprinkler systems’ components overheads as sprinkler heads, on the walls as standpipe connections, and even behind the scenes as annunciator panels for alarms. Recognizing these components as life-saving security devices allows us all to focus on the more immediate aspects of our busy lives. But consider the fire sprinkler system in all its forms. Sprinkler systems in New York typically are one of four types of systems designed to retard or extinguish a building fire.
Pre-action systems. Pre-action fire sprinkler systems are designed to work in conjunction with a smoke or heat detector. Pre-action systems work so that no water is actually in the system’s pipes until a fire is detected and the system is called upon to fight it. Pipes are typically filled with air until an alarm goes off. Two switches then activate to release the air in the system and to being flowing water through the pipes to the sprinkler heads. This kind of system is preferred in facilities with contents that may suffer from water damage when the system activates; installations in libraries, museums, and computer rooms.
Dry-pipe systems. Dry-pipe systems are similar to pre-action systems in that the pipes hold no water until a fire is detected and the system is activated. Once activated, the system releases the air in the pipes as the water fills them. Dry-pipe fire sprinkler systems are ideal for applications where the facility is unheated. Water in the pipes of an unheated structure can freeze and rupture the pipes. Relieving the system from carrying water constantly removes the chance for water to freeze.
Wet-pipe systems. Wet-pipe fire suppression systems constantly hold water in the pipes of the sprinkler system. Wet-pipe systems are the quickest to react and actually get water on the fire, and these types of systems are commonly found in high-rise office and apartment buildings. Wet-pipe systems are typically low maintenance and highly effective.
Deluge systems. Deluge fire sprinkler systems have nozzles that are fixed open and when the system is activated by smoke or heat detector, the pump water through the system and out the heads to flood an area with water or chemicals to fight the fire. Facilities with a lot of floor space or sprawling foot prints benefit most from a deluge system of fire suppression.
