How Do Fire Sprinkler Systems Work During A Home Fire?

Posted on: 20 April 2016


When a home fire occurs, a family can lose all their belongings in a very short time. However, if a home has a fire sprinkler system, this can help put out the fire before it gets out of control. The sprinkler system has a built-in sensor that senses when smoke is inside the home. If a fire begins, the sprinkler system will turn on and the fire can be extinguished more easily. Many homeowners have either a wet pipe fire sprinkler system or a dry pipe fire sprinkler system installed in their homes that will activate should a home fire occur. This is how these systems work. 

Wet Pipe Fire Sprinkler Systems 

One of the most commonly used types of indoor fire sprinkler systems is the wet pipe sprinkler system. This system has water stored under pressure directly in the pipes so that it is ready to be released at the first sign of a fire. When the sensors built into the sprinkler heads detect smoke or an abnormal rise in temperature in the room, the water begins to spray and this helps extinguish the fire.

However, it is important to maintain these sprinkler systems properly. If they are not insulated during cold weather, the water inside the pipes can freeze and cause damage to the pipes. Occasional leaks can also occur if the pressure for the water is too strong.

Dry Pipe Fire Sprinkler Systems

Dry pipe fire sprinkler systems work in much the same way as wet pipe fire sprinkler systems. Although, water is not stored in the pipes. Instead, the pipes are filled with pressurized air or pressurized nitrogen. A valve that remains closed until it is activated controls when the water is released.

When the sprinklers detect heat in the room, the air escapes to the valve and the valve releases the water through the pipes and into the sprinkler heads so it can spray out into the room. There is a slight delay in the time after the heat is detected until the sprinklers release water. However, this type of sprinkler works very well at extinguishing a home fire and preventing severe damage from occurring.

Having a sprinkler system installed in a home is a much better alternative than trying to only use a handheld extinguisher to put out a home fire. The sprinkler system activates on its own without having to be turned on manually. This helps extinguish a home fire immediately and also reduces the possibility of getting burned by trying to put a fire out on your own.
