Thanks for quick reply. Last time it happened engineer said he couldn’t isolate as same wiring had been used for tamper circuit as main circuit. Not sure I follow. He was the engineer who fitted the garage alarm but didn’t fit the main alarm.
Alarm goes off. Says tamper garage. My code...
my 9851 is 15 + years old and has just started going off randomly. It says tamper garage and then allows me to reset with my user code. But then goes off for a while. Has happened once a month. Engineer says too hard to fix and probably a circuit board error so need new alarm.
Went off this...
