How Do Fire Sprinklers Work?

In situations where a building has a smoke detector, though they alert occupants to a potential emergency, sometimes this is not enough. Especially in places such as care homes where tenants may need extra time to evacuate. And this is where fire sprinklers stand out from other alarm systems. But, how do they exactly work?

At RAD Fire Sprinklers, we always advocate the installation of sprinklers in domestic and commercial buildings. Check out this helpful guide to how automatic fire sprinklers work and why they are so beneficial.

 

Fire Sprinklers Detect Heat

Contrary to popular assumption, fire sprinklers are not activated by smoke. Because heat is carried upward by smoke from a fire, it’s an easy mistake to make. In fact, it is difficult to accidentally set off these systems.

Fire sprinklers work because they are activated by high heat. When a fire starts, the air directly above it quickly heats up. This hot air rises to the ceiling and spreads. When the air becomes hot enough and reaches a sprinkler head, a chain reaction occurs.

A glass bulb filled with a glycerin-based liquid is found in most sprinkler heads. This liquid will expands when it detects a heat over 56°C.

 

Suppressing the Fire

The fire sprinkler system is connected either to the town main or a storage system within the property. The pressurisation of water in a fire sprinkler system is critical. This permits the water to jet outward in an arc, dousing the fire more thoroughly and preventing it from rekindling.

However, another misconception, not every sprinkler head will release water at the same time. If there is a fire in the kitchen, the sprinkler in your loft conversion will not go off; causing unnecessary water damage. Instead, the sprinkler head that is closest to the flame will suppress the fire in that room. Only if the fire starts to spread will more fire sprinklers release water.

 

When Should You Install Fire Sprinklers?

Commer fire sprinkler systems are installed by properly qualified contractors who adhere to LPCB guidelines and standards. Sprinklers are best installed while you are building a new home or modifying an old one in order to minimise disruption.

Fire sprinklers contribute between 1% and 2% of the entire cost of construction across the country. Retrofitting sprinklers during remodelling is often more expensive and the cost is determined by the existing structure. Many insurance companies provide a variety of savings to homeowners who use sprinkler systems, making it beneficial to shop around.

 

Work with professional installers to get the best quick response sprinklers, specifically for your building.
