The likely causes are that either:

– Your door contact is not activating when the door closes. In this case, your device will not arm if the contact wires are removed from the device.

– Electric power was applied across terminals 5 and 6. In this case, your device will still arm after the door contact wires are removed from the device.

Two possible reasons:

1. Tamper plunger is not being held back by the screw on the upper left of the front of the device. Make sure the unit is mounted and the top left tamper screw is installed. Check That the security plunger is engaging the security micro switch on the back of the PCB.

2. Set to auto rearm(non-extended bypass) and the magnet on the frame not aligned properly. Isolate the device by using a jumper to simulate the door closure in inputs 5 and 6. If your device works, then check you magnet switch continuity. The magnetic switch is a closed contact when the door is closed and opens when the door is opened. These two wires should be connected to terminals 5 & 6.

The status indicator is set to “on”. The battery life when using the status indicator will only get up to 3 months.

This can be turned off by the slide switch on the circuit board as shown in the picture below. Remove the battery first, adjust the switch, replace the battery and rearm.

With status off, battery life can last for up to 12 months.

Note: Use name brand alkaline battery. If unit has gotten wet, it will drain the battery.
