Wall tamper contact
To use the wall 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. Mark the position of the hole on the wall where the
sensor is to be fitted. Drill a hole on the mark, then insert
a suitable wall plug and insert a screw (M3). The screw
head must not be more than 2.5 mm from the wall
surface.
3. Fasten the rear housing cover to the wall, making sure
the head of the screw protrudes through the opening
and presses against the tamper switch after the sensor
housing is attached (see illustration). If this is not the
case, then the screw must be unscrewed further as
necessary.
