We fit quite a few of these and have noticed an ongoing problem which may assist anyone having similar problem .
The panel front cover tamper spring has a notorious habit of NOT switching when the lid is fitted . Then you get a tamper fault on the keypad and you're thinking it could be anywhere .
If you just press the top of the front cover lightly , the switch operates ....you just need to stretch the spring .
Could save you time in checking detectors , climbing back up to the bell etc.
