Sprinkler Systems: The Quickest Response in case of Fire.

In our previous Blog we mentioned Smoke & Heat detectors which caution us in case of Fire.

If you’ve read that article on smoke detectors, you’ll know there are some pretty clever ways of detecting fires by using electronic circuits to sense the smoke they give off; or heat and trigger the alarm as early warning.

So the alarm system is triggered , we exit the room / building , but should we allow the fire to continue and destroy our property

It makes sense to have a fire-fighting system that can react the moment trouble strikes, not just sounding an alarm but automatically putting out a fire as quickly as possible. That’s exactly what fire sprinklers (fire-suppression systems) do.

Sprinklers aren’t just for business buildings: they’re well worth having in homes. According to the Home Fire Sprinkler Coalition of USA , a sprinkler adds about 1 percent to the cost of a building but (fitted alongside a smoke alarm) can reduce the risk of death in a home fire by 82 percent.


How to put out fires…..  Basic Principle

Remember the fire triangle: if you can remove either the heat, the air (oxygen), or the fuel, you can usually put out a fire.

You probably know that water is one of the best, all-round substances for tackling fires; that’s why firefighters use it, after all. Why is water so good? First, because it’s property to absorb heat ; it removes the heat from a fire—breaking what’s known as the fire triangle by taking away one of the three key ingredients (heat, oxygen, and fuel) that all fires need. (Water-based fire extinguishers work the same way)


Your automatic fire-fighting system is going to use water. How will it work? If you’ve seen firefighters tackling a blaze, you might have noticed them putting water up into the air so it falls as a spray over a wide area. Maybe what you need is something like an automatic fire hose attached to the ceiling of your building that could work the same way.


Unfortunately, what you don’t have at your disposal is lots of highly trained firefighters: you can’t have people sitting around all day and night on the off-chance that a fire might break out. So what you need is a fire-hose that switches on automatically when there’s a fire nearby—and, ideally, only in the immediate vicinity of the fire itself.


Right, so how will the sprinkler switch on automatically?

The fire sprinkler head opens when heat causes the red liquid-filled capsule to break. That opens a valve, allowing water to spurt through, bouncing off the flower-shaped deflector to

In reality, each sprinkler head has its own heat sensor (red capsule ) and each sprinkler will operate in its vicinity ,only when the temperature reaches between 155 and 165°F.

A fire in the garage for example, will activate only the sprinkler(s) in the garage.

(Types of Sprinklers will be discussed in our next Blog.).
