Honeywell long range detectors

[scrimshanker]

Hi All

 

I've come across an issue at a site where its been fine for over a year and now im getting spurious alarm signals between 12am and 3 am from various long rang detectors. It started with just one detector so it was changed but now its multiple including the changed one.

 

Its a large builders merchant with a large warehouse, there isn't any sign of animal life. The only thing is the warehouse is rather hot and I wondered whether the cooling of the building would effect these particular detectors. The thing is now isn't as hot as it was so i'm a little stumped.

power supply issue?

Are they mounted on a solid base or outer cladding ?

Hi

 

Not checked the volts at each detector but they aren't all feed by the same Rio

As for mounting, they are all mounted on the inside of the exterior metal cladding.

are all the rios that these detectors are powered from on the same psu?

Likely the cladding is moving with heat expansion.

Microwave can only help minimise false alarms if device is fixed to a solid surface.

Normally I'd agree but it hasn't done it during the really hot spell in June!

 

Although it is far more humid now. 

 

It has to be heat related, I was wondering whether anyone has had issues with these detectors before due to heat?

are they going off or going high resistance

There's no sign of anything technical yet.....
