My Honeywell Optima Compact intruder alarm system, now 16 months old, is activating tamper alarms at random times, in both Day and Set modes. These reset straight away. I have linked out the panel terminals for both the sensor tamper loop and the remote LCD keypad tamper loop, which takes a wiring or tamper switch fault out of the equation. The tamper alarm still activates every couple of days (or nights .... it went off at three this morning!). Question; does this indicate a control panel hardware fault or a software fault? And if the panel is faulty, is it still under warranty?
