A question that is always popping up by an owner of the property:

Should I invest on a fire sprinkler system?

The answer is, Yes!

The fire sprinkler system is a great choice against emergencies that involved fire for most buildings. You can be guaranteed total protection for the occupants and the things inside the premises.

Fire sprinkler head

Fire sprinkler head – the main component of the fire sprinkler system that discharges water when the fire has been detected. It comes in not one but an assorted design. Each sprinkler head contains a trigger mechanism, which releases water onto the fire.

Common misconception of fire sprinkler system

There is a common misconception of the fire sprinkler system that they trigger by smoke.

  • For your information, the device has been placing with a glass bulb alongside with its sprinkler heads. The glass bulb contains a glycerin-based liquid in which, detecting fire through an increase of temperature.

  • As the surrounding temperature increased, the temperature at the head of the sprinkler will increase too. At a certain temperature; depending on the bulb itself, the liquid inside the bulb expands, break the glass and thus, activating the sprinkler head.
  • There is various colour of liquids in these glass components. Each of them indicating a different temperature required for the heat to break the glass.

Activation method

The method of activation can be varying – depending on the type of fire sprinkler system installed. Implementing to all of the fire sprinklers, once the glass of the bulb breaks, the sprinkler head will automatically release water. However, the way water is stored and be delivered through pipes depending on the type of the sprinkler system.

As we all know, all the main types of a fire sprinkler system; wet pipe, dry pipe, deluge, and pre-action are all used pressured air. In the wet pipe sprinkler system, pressure in pipe ensures the water is delivered quickly. For dry pipe and pre-action fire sprinkler system pressured air is used to fill up the pipe, instead of water. Once the air is released, due to a fire, the water will flow through the pipe.

In a post-fire emergency situation, it is a myth that once a fire is detected, the device will turn off. The fire sprinkler system is designed to detect a rising temperature at each of the sprinkler heads and goes off only if when the fire reaches the sprinkler. If you require a sprinkler system where all the sprinkler heads go off at the same time, then you need a deluge sprinkler system.
