1. Remove the two stickers featuring the serial number from the back box.
2. NOTICE! Do not stick any stickers on the radio module! The stickers may
impair the send and receive properties of the radio module.
3. Stick one sticker in the battery compartment of the radio gateway so that you
can identify the radio gateway even when it is screwed down.
The other sticker is intended for sticking in the building plan.
4. Break out the cable entries according to the cable supply.
Recess-mounted cable entry:
Break out openings in supporting surface of back box.
Surface-mounted cable entry:
Break open openings in face end of back box.
5. Guide cables through back box and use two screws (max. diameter 4.3 mm) to
fit back box on a level surface.
6. Prepare the detector line wires such that they can be connected to the 'LINE'
spring clip later on.

or connection terminal (order separately). To test the detector line, these must
not be interrupted.
8. If the detector line cables are shielded, connect the shieldings of the two
detector line cables (coming and going) to the 'SHIELD' spring clips. Use a
screwdriver to remove the load from the spring clip so you can slide in the wire.
