Notice!
Suspension hook
After the wall-mounting bracket is mounted, the enclosed suspension hook can be used to
store the housing while working on the connections with both hands free.
Therefore insert the suspension hook into the hole at the bottom of the wall-mounting
bracket and thread the other end of the suspension hook through one of the holes designated
for the snap-in latches on the sides of the housing.

The signaling device must be mounted vertical, with the LED lamps always at the top and
the speaker always at the bottom (for water drainage).
In case of difficult installation conditions (for example walls with full thermal insulation or
roughcast plaster), an adapter module must be used.
When mounting, clearance (to roof overhang) of at least 350 mm for IUI-BES-AO and of at
least 280 mm for IUI-BES-A must be allowed for.
Push in the snap-in latches on both sides.
Push up the housing as far as possible.
Turn the threaded bolt to the left to unscrew and adjust it.
Lift off the housing completely.
Mount the wall-mounting bracket onto the wall with four appropriate screws (not
included). If you are using an optional wall tamper, mount the wall-mounting bracket
directly on top of it.
Connect the cables to connector A (wall-mounting bracket). The terminal resistors (12k1)
are already fitted to connector B (electrical module). If required, the correct resistors
must be fitted depending on the type of control panel.
Optionally connect the wall tamper.
Lift the housing on the wall-mounting bracket as far as possible.
Adjust the threaded bolt by screwing on the right.
Push down the housing completely.
Glue a seal in place over the right-hand snap-in latch.
In case of a VdS-compliant installation: Screw the black screws on both sides of the snap-
in latches.
