Do Fire Alarms Set Off a Sprinkler Fire System?

sprinkler fire systems

It is important that the responsible person of a building is aware of the correct fire safety procedures; whether this is with a sprinkler fire system or with alarms. In cases where both are present, some might ask whether they will react badly to each other. Or even, cancel each other out.

Here at RAD Fire Sprinklers, we advocate the use of automatic fire sprinklers in buildings across the UK. No matter whether the property is residential or commercial, the installation of a sprinkler fire system can benefit a building in various ways. Find out all you need to know here.


Do Sprinklers Go Off When an Alarm is Activated?

As they are two separate systems that are not connected, a fire alarm will not trigger sprinklers. Sprinklers are not an early warning system, like smoke detectors or fire alarms. Fire sprinklers are designed to respond to an actual fire, not to the warning indicators of an oncoming fire. The fire sprinkler heads are usually activated independently in most systems, which is highly useful for putting out fires just where they start.

The only exception to this is in deluge systems, for which an electronic control valve can be linked to a fire alarm; dispersing the water through the pipe to deal with the situation. These sprinkler fire systems, however, are primarily used in high-risk situations where the flames could easily spread quicker; for example, in warehouses or high-rise buildings. So, in residential homes, deluge automatic fire sprinklers are generally not required.

Consequently, fire alarms are more likely to go off than sprinklers, as they will react to a much lower heat present. For example, using a hob or an oven can occasionally set off an alarming system, however, you can be certain that it will not set off any sprinklers. Not until the temperature is over 56°C and a flame is detected.


Do I Need Both an Alarm and a Sprinkler Fire System?

Like other open questions, the answer depends on the certain circumstances surrounding the incident. Fire alarms are early warning systems; detecting a potential fire risk and give people either time to evacuate or deal with the flames.

Whereas, sprinkler fire systems are designed to respond to an actual fire, not to the warning indicators of an oncoming fire. The fire heads are usually activated independently in most systems, which is highly useful for putting out fires just where they start.

Make sure you consult with an accredited sprinkler company, as well as your insurance company, for the best outcome. Typically, however, there is no need for both prevention systems.


What Else Can Set-Off Fire Sprinklers?

Despite what the movies might tell you, it is actually quite hard to accidentally set off a sprinkler fire system. Only temperature will set off fire sprinkler heads; so you can light your candles in peace.

As previously mentioned, once the temperature in a room is over 56°C, the subsequent sprinkler head will disperse water to suppress the flames. However, in areas such as lofts and extensions, these rooms can quickly overheat and the sprinkler may not be able to tell the difference. Ensure your sprinkler heads are correctly placed in each room and work with professional sprinkler installers to understand any potential risks.

I have used RAD for a couple of projects and found them to be good to deal with. They did a pair of 3 storey open plan houses and seven three and four story town houses. The sprinklers were to improve fire safety, allow more flexible space and comply with building regulations. The sprinklers were far more cost effective than the mist type systems and look very discrete when installed.

My requirement was a bit unusual for RAD in that I wanted a mist system in one room of a rented house. I had no drawings or technical back up. RAD were very helpful and repositioned the unit after the initial installation. Luckily with the help of Sonny, the engineer it all worked out very well.
