Hi AJ
Welcome to the forums

I'm sure alot of the gang here will be able to assist with your query...

hat type of premises are you having problems with? is there a concentration of Unwanted Fire Signals (UwFS) in one particular area for instance?
Generally UwFS can be caused by several factors. Incorrectly sited smoke detectors are a common culprit, thripps / dust in detector heads is another. Older detector heads can become 'over sensitised' or simply spring up faults due to old age!.
The thing to do is look at where you are getting the UwFS (are they in similar types of rooms or environments for instance). Then consider why they might be occuring.
A hotel I dealt with for example suffered from several UwFS a day. Steam from the en suite bath rooms would set off smoke detectors in bedrooms (the guest would take a shower open the door from the bathroom into bedroom and set off the detector) As a result the smoke detectors were moved further away from the bathroom door and it solved the problem
We were also called many times to a sheltered home responding to fire alarm activations. Quite often we found the detectors had activated purely because of dust!
