I have never had a problem with this alarm in 22years, however it now goes off on a random basis in the early hours of the morning, The zone showing is the sensors how do I omit these ? Got the installation book but not the working instructions.
The sensors, you have more than one sensor on a zone?
How are you expected to trace the detector causing the problem then?
One Zone = One detector is the norm, 2 or more could not be more wrong
