Common myths about fire sprinkler systems

Common Fire Sprinkler Myths

We get asked many questions about fire sprinkler systems, so here are the main ones – to help you to understand them a bit better and know a little bit more for your project.


  • Modern fire sprinkler systems don’t always need a huge water supply as they can be plumbed into the mains, drawing water only if and when they are activated
  • Sprinkler systems are activated by heat and not smoke. They contain a small glass tube of liquid which expands when it reaches the temperature created by the fire – around 57 Celsius.
    It expands and triggers the sprinkler head to release water.
  • Burning your toast won’t set fire sprinklers off – because it is heat activated.
  • If a sprinkler head is triggered in one location, the other heads around the house are not necessarily activated. You may have seen it differently in films – but that’s just for dramatic effect!
  • Sprinkler heads are discreet and blend into a ceiling without ruining the aesthetics of a room.
  • Sprinkler systems usually interface with a domestic smoke alarm or fire panel. The system triggers the alarm system, not the other way round.
  • Sprinkler heads can be fitted that permit an open plan design to cover the exit routes as required by building control.
  • Sprinkler systems can be fitted to older properties as well as new-build ones.
  • Sprinkler systems are built to British Standard BS9251:2014.

Mist system was a great solution for our renovation needs and them team at RAD have been great. Always communicated clearly and been on hand to discuss over the phone as needed. Would highly recommend!

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.

It has been a pleasure to deal with RAD for installation of fire sprinklers at our site is Sevenoaks. They were fast, professional, working to time and quote, which made it easy to work with them.

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.

As somebody who feels that it should be a necessity for all properties to have fire sprinkler systems, I am a big fan of this company. I have used them numerous times to service my home system and they are very knowledgeable. I would highly recommend their service.

One look at Rad Fire Sprinkler's website will tell you that these guys know exactly what they are talking about when it comes to Fire Sprinklers and the legislation surrounding fire safety. A very trustworthy company.
