Activation of backtamper:
1. Remove the tappet
from the holder
. To do so, a small mechanical resistance must be overcome.
2. Cut off the blocking pin
.
3. Insert the tappet
back into the holder
.
If the detector is mounted correctly to the wall, the pressure pin
pushes the tappet inwards to activate the
cover contact.
If the detector is torn away, the pressure spring
pushes the tappet outwards and the cover contact is
triggered.
