when i turn on the lights in the house the panel activates a tamper fault on zone 3 & 4. This isnt everytime but i have changed the battery and the fault still came up. the panel is wired of the ring main and into a fused spur so there should be no issue there. If anyone can think of why this is happening before i call an engineer of just buy a new alarm
when the alarm was installed, if it was run along side mains cable for a distance the the cable may be ac induced. you may need some one to fit an act1313 suppressor on the aux of your alarm panel
