Corner tamper contact
To use the corner tamper contact, proceed as follows:
1. Open the hole on the rear of the sensor. Make sure that
the opening is large enough for the head of the tamper
switch.
2. Attach the enclosed corner tamper bar to the desired
position. Ensure that the pin on the end of the arm is on
the left-hand side.
3. Attach the rear side of the sensor onto the bar and fasten
it to the wall. Ensure that the pin on the bar passes
through the hole on the rear housing side without any
obstructions.
