The fire sprinkler system heads we see above us in so many public spaces are there to keep us safe from a fire. We take for granted that these systems are life savers and not just building-code requirements. These fire suppression systems are sophisticated systems delivering a very basic service: water to extinguish a fire. And because these systems are not constantly active, but rather they lay in wait for the unexpected to strike, their maintenance and repair are critical functions during down time.
The Seven Types of Fire Sprinkler Systems
• Wet pipe systems—are the most commonly experienced fire suppression system in use today. Wet pipe systems supply pressurized water through pipes and to sprinkler heads installed throughout the building. When a fire is detected, the sprinkler heads in the affected areas activate and rain water down on the fire. Wet pipe systems are effective, reliable, and easy to maintain.
• Dry pipe systems—probably the second-most-common type of fire suppression system in use today. These systems do not hold water within the pipes, which could burst if they ever froze. A positive air pressure is maintained in the pipe to keep closed a check valve to prevent water intrusion from other sources, like other pipes. Dry pipe systems are most often used in facilities that go unheated during cold winter weather (like parking garages). When a fire is detected, a valve releases the air pressure within the system, and that allows water to flow freely to extinguish the fire
• Deluge systems—a fire suppression system where all the sprinkler heads that are connected to the water deliver pipes “open” (i.e., not individually activated). No water is present in the pipes on a constant basis, like a dry pipe system. When a separate fire detection system detects a fire, it sends a signal to open a valve and lets water freely on the fire.
• Pre-action systems—are specially activated systems used in such facilities as museums and libraries. Pre-action systems combine the features wet, dry, and deluge systems to protect valuable installations from accidental or indiscriminate fire suppression methods.
• Foam water sprinkler systems—uses a mixture of foam and water through special nozzles to encapsulate a burning transformer, fuel tank, or vehicle.
• Water spray—similar to foam water sprinkler systems, but spraying only water.
• Water mist systems—sprays tiny droplets of water into the atmosphere where a fire is present. The effect is to cool the atmosphere and reduce heat damage from the fire.
