Why Is My Device Going Straight Into Alarm?

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.
