It seems I need a heat detector.  We have an extension to build on to our house, and the doorway between what will be the kitchen and the existing dining room - the current rear door - has a brick arch, and is too low to realistically fit a fire door too - or any door, come to that.

I can't find a heat detector which is compatible with the 240v 9v backup smoke detectors I have already bought!


Is the answer to buy a fire alarm panel and connect a heat detector to that, and have two separate systems, or will that still not satisfy regs?

Or shall I just bite the bullet, fit a lintel and a firedoor and take the firedoor out again after Building Control have finished with me.

Every time I think I have got this job sussed it gets more complicated.  

Am posting this is a slightly different form in the alarms section as well.


Thanks JohnD

Further thought - are heat and smoke detectors  compatible with burgular fire alarms and if so will that suit regs?

Less then a tenner would be ideal.....

think I have found a heat sensor which is compatible with my smoke alarms, thankfully.
