Mains Smoke Alarms

Just had a call from a customer who has reported that there interconnected smokes are going off early in the morning, All at once.

Now then, The say they have changed the batteries tried hoovering them but still no joy.

There is clearly a fault with one on the on the circuit but as for testing is it just trial and error or is there any means of testing?

The only factor I can think of when they are going off is the cold. Would this make a difference and why?

How old are they? There should be a date mark on them and could be they need replacing.

Its a new build ish. Id say 4-5 years old. not sure if the smokes are the original i would presume they are. Ill take a look when I go to the job.

if they the type linked by a three core wire then go and disconnect the signal wire, leaving them not linked together. leave it till the faulty one will give alarm.

They don't like the intense cold , Check for operating temperatures for the make and compare to temps in unheated areas - halls, stairwells etc.
