How long do fire sprinklers stay on? Domestic fire sprinklers are set to run for 10 minutes for pump and tank. If water mains fed then a home fire sprinkler system will usually run until the isolator – manual stop value is turned off.
When the sprinkler head is activated, a valve releases the compressed air through the sprinkler head. Once all of the air is released, the pressure in the pipe changes, allowing water to fill the system. Dry pipe systems have a slower reaction time (up to a minute delay).

Why are sprinklers so important?
There is clear evidence that sprinklers are effective in stopping fires spreading and putting them out, ultimately saving lives. Fire and rescue services across the country advocate the use of sprinklers, and play a key role in promoting a better understanding of the benefits of sprinklers as part of a package of fire safety measures.
How do sprinklers operate?
Fire sprinklers are individually heat-activated and connected to a network of water pipes. When the heat from the fire plumes hot gases reach the sprinkler and at a specific temperature (usually about 68 deg. C) that sprinkler activates delivering water directly to the source of the heat.
How can we be sure sprinklers will work in a fire?
Most sprinkler systems are very simple. There are normally no moving parts to fail. The pipes are full of water, usually from the mains supply. The sprinklers over the fire burst open when they get hot and spray water on the fire. If you have water in your pipes the sprinklers will work.
It’s clear that sprinklers are effective in saving property and life. There are also additional benefits dependent on the building they are installed in.
Sprinkler installation can also help in the design of a new building by allowing much more interesting use of space. New building codes work on a performance-based approach to the safety of a building, so by including sprinklers, designers can achieve greater freedom to fulfil their overall vision. They can include features such as: 1. Larger compa...

In the Chief Fire Officers Association’s Business Case for Sprinklers, it was established that it can take 20 minutes for the fire service to establish the resources required to safely deal with a fire on upper floors. Fire sprinklers buy precious time and therefore save lives.
May 10, 2021 · It is also a requirement to change over your sprinkler system to either water or air, depending on the time of year. This must be done to ensure your system can activate in the event of a fire, and is mandatory as part of maintaining your sprinkler system as stated in the LPC Rules.
