Red Hawk Fire Protection has experience with all of these systems and can custom design a system for your specific needs. This type of system is often found in industrial parks. Tanks of flammable liquids, for example, often use deluge fire sprinklers. This fire sprinkler system is easy to maintain and cost effective.ĭeluge fire sprinkler systems also need a smoke or heat detector like the pre-action system but uses open nozzles that can be used when a hazard is present and the need to put a fire out quickly is urgent. Wet Pipe systems are the most common type of sprinkler installed in buildings are often found in multi-story office buildings and other high rises. Wet pipe fire sprinklers always have water in them, resulting in a quick reaction to a fire. This type of system is typically used in buildings such as warehouses in climates where the temperatures are below freezing during parts of the year. This causes a short delay in water discharge but is ideal for buildings with low temperatures where there is increased risk of pipes freezing. It is used in buildings such as libraries and data center where an accidental triggering of the system would cause extensive damage.ĭry pipe fire sprinkler systems are similar to pre-action systems as they use pressurized air in the pipe which exits before water flows. The pre-action system works best in places where the sprinklers are only necessary when there is an actual fire. This type of system helps prevent accidental triggering of water flow due to mechanical failure or false alarms.

A pre-action system requires two triggers to start water flow. Water will only pass through the system when the smoke alarm or detector goes off. Pre-action fire sprinkler systems are filled with air. Below are descriptions of the four most common types and their applications. Not only does it help stop fires when they happen, it can lower your insurance liability. Even when not required by law, installing a fire sprinkler system is a good idea.
