Installation location
The recommended mounting height is 2.3 m. The unit can be
mounted between 2.1 m and 2.5 m without adjustment, when
mounted on a vertical surface.
It may only be mounted on permanent, vibration-free walls.
Large objects situated before the detector obstruct the
detection range. The detector may not be subject to direct
sunlight, heat sources and strong draughts (e.g. fans of
air-conditioning systems) to prevent false alarms.
Preparation and mounting
The screw must be loosened (do not unscrew fully) to
remove the cover. Then insert a flat screwdriver into the slot
underneath the screw and twist it. When the detector is
opened, the electronic circuit board can be unlatched via the
two catches and removed simultaneously from the plug-in
socket. On the lower housing section, the selected cable
entry points and mounting apertures can be knocked out.
Introduce the cables, connect them and provide strain relief
using the enclosed cable ties.
Wiring
The electronics are reinstalled after mounting the lower
section.
Caution:
During all work, the light-sensitive sensor may not
be touched. To refit the cover, engage the upper half using
the two lugs and push both halves together (there will be an
audible click), then tighten the screws.
Connect the detector as follows:
