Mounting
The sounder is suited for wall and ceiling mounting. For mounting dimensions, see the
dimension illustration (on page 12). The wall bracket included in the box is fastened with 2
screws (
∅
6 or 8 mm). To connect, loosen the 6 lid screws and remove the lid. The
fasteners and the mounting surface must be able to safely carry the weight of the sounder.
Installation
Prior to leading the connecting sounder cables through the cable gland, 100 – 130 mm of
the isolation must be removed. Before connecting the single connectors to the terminals,
remove 8 to 10 mm of isolation from the connectors.

After connecting the loudspeaker, place the single conductors of the connecting cables
flatly across the connecting terminals, in the direction of the cable gland.
Warning! To avoid the connectors getting pinched, do not place them over the sealing
edge.
Use sufficiently long cables to facilitate positioning of the sounders at a later stage.
Close the lid
Prior to closing the lid, the sealing surfaces and the sealing must be checked for damage
and dirt, and cleaned if necessary. Damaged seals must be replaced by original seals from
the manufacturer.
Put the lid on. Make sure the lid sits straight, and that the „lid fastener“ has not been placed
across the threaded lid bolt or across the sealing edge. Then turn the lid screw as far as it
goes, and tighten lightly.
Positioning the sounder
Swing the sounder in the desired position and tighten both side screws on the wall bracket.
Operating position
In order to avoid a reduction of the volume due to dust, rainwater or other foreign matter,
the horn should be mounted horizontally or facing downwards.
Care and maintenance
The sounder is maintenance-free. In very dusty or dirty surroundings, the sounder should
nevertheless be cleaned with a damp cloth from time to time. Never use sharp objects for
cleaning.
Special operating conditions
In order to maintain the given listening quality, the sounder must not be mounted in close
vicinity of sources of magnetic fields with technically relevant frequencies.
