Combined heat and smoke alarm

Jun 09, 2021 Last reply: 5 years ago 10 Replies

I have a problem with an EI44 heat alarm in the kitchen, which goes off when the gas hob is on. It's a small kitchen, and it's mounted at about the maximum distance from the hob.



The best solution would be to replace it with an alarm that requires



*both* heat and smoke before it sounds.

Anybody have a suggestion, please?


I very much doubt if this would comply with fire regulations. I am sure an alarm has to be triggered by presence of smoke (with heat alarms possibly optional) and introducing a two-stage trigger would not be permitted.

You could locate the smoke alarm just outside the kitchen, and the heat alarm in it such that either could raise an alarm.

There is a smoke alarm on the landing outside the kitchen.

Is this a recent problem or has it always done it?

The Ei144 is a fixed temperature alarm set to 58 deg.

I was wondering if it may have gone out of calibration.

There are combined heats and smokes but they do not work the way you want them to:-(

BTW Have you seen these?

I had this problem and I was advised to instal a 'rate of heat rise' sensor. This solved it.

Thanks, Bill. That looks very promising. :)

My sodding alarms go off if I have a shower and don't close the bathroom doors...

Then swap from ionisation to optical.

That's pretty much what AICO said to me.

Not enough of a problem to be worth the effort
