5 Mounting / Installation
The alarm sounder FDS221 requires an addressed detector base. The detector
base is mounted on the wall or on the ceiling.
The device must be easily accessible for commissioning and maintenance so that
it can communicate with the detector exchanger and tester FDUD292 or the
intelligent detector tester FDUD293 via the interface (MC link).
The alarm sounder FDS221 cannot be used or removed with the detector
exchanger and tester FDUD292 or the intelligent detector tester FDUD293!
Proceed as follows when installing:
1. Install a detector base.
– For recess-mounted cable entry: Flat, addressable detector base FDB222
– For surface-mounted cable entry and cable diameter 6 mm: Addressable
detector base FDB221 or FDB221-AA
– For surface-mounted cable entry and cable diameter > 6 mm: Base
attachment FDB291 and addressable detector base FDB221 or FDB221-
AA
– For applications in wet rooms: Base attachment wet FDB295 and flat,
addressable detector base FDB222 or base attachment wet FDB295 and
addressable detector base FDB221/FDB221-AA
2. Place the alarm sounder FDS221 into the detector base and turn the alarm
sounder FDS221 until it snaps in.
