7. Tamper Alarm Facility.
The tamper alarm will automatically arm itself when the gate is in the closed position and will trigger
the alarm relay if the gate is moved or forced off the closed limit switch without a valid trigger.
If latch mode is configured, the relay will switch every 3 minutes until the alarm is restored.
If impulse mode is configured, the relay will trigger only once.
Any valid gate or pedestrian input trigger will cancel the tamper alarm which wills automatically re-
arm once the gate is again in the close position.
The alarm can also be disabled for maintenance by opening the gearbox release and pressing the
remote control push button (confirmed by 3 short beeps). The alarm will remain disabled until the
gearbox release is closed and the gate closed position re-confirmed.
8. Anti-hijack/Alarm.
a) When the tamper alarm function is active and the gate receives a valid trigger but is
obstructed and cannot move or did not move more than 150mm, the alarm or siren will activate.
b) If the beams are obstructed or blocked when a trigger is received, the gate will open but will
then also sound the alarm.
c) If the gate should be forced or moved from the close limit in any way without receiving a valid
trigger. The alarm will be activated.
d) Should the gate be tightened up in any manner and therefore on trigger cannot move or cannot
move more than 150mm. The alarm will be activated.
