Over 1,000 fire accidents occur in the United States each day. A properly installed fire suppression system (also called a fire sprinkler system) can limit property damage and save lives by extinguishing a fire before it can spread.
A fire suppression system consists of three major parts: sprinkler heads, a water supply system, and pipes that connect the two together. Most sprinkler heads consist of a nozzle held shut by a glass bulb designed to break under intense heat. When the heat from a fire destroys the glass bulb, a valve in the water supply opens to let water rush out of the nozzle.
Each type of fire sprinkler system serves a specialized purpose. A Metro Fire sprinkler specialist can help you determine which of the following fire sprinkler systems best suits your needs:
Wet Pipe Systems
In wet pipe systems, the pipes that connect the water supply to the sprinkler heads are always filled with water. This allows the system to respond to fires almost instantly. This system is typically used in heated buildings, where sprinkler heads are mounted on the ceiling of each room.
Dry Pipe Systems
One disadvantage of the wet pipe system is that water can freeze inside the pipes. In a dry pipe system, the connective pipes are filled with air instead of water until the system is activated. Dry pipe systems are often installed on outside property adjacent to a building.
A deluge system activates multiple sprinkler heads at once. Sprinkler heads do not use glass bulbs to sense fires; instead, the system is linked to a smoke or heat detector or manually activated.
In pre-action systems, water is not released into the pipes until a smoke or heat sensor is activated. The system then behaves as a wet pipe system. This system prevents a fire suppression system from accidentally activating. They are often installed in museums or buildings containing sensitive electronics.
Foam Water Sprinkler Systems
This system sprays a water-foam mixture designed to efficiently extinguish chemical fires.
Water Spray Systems
Water spray systems are specialized deluge systems that spray water on a specific area or piece of equipment, as opposed to a general area such as a room.
Water Mist Systems
Water mist systems spray water vapor instead of liquid. This system limits water damage and is advantageous in areas where water is limited.
