Mounting; Mounting With Ingress Protection For Sounder Base - Panasonic 4479 Manual

7. MOUNTING

The addressable sounder base must be mounted in the ceiling. Screws are not supplied.
(Measure in mm)
The addressable sounder base cannot be used without a detector. The short circuit isolator is in the detec-
tor, so without detector 4400I you will have an open circuit.
If the addressable sounder base is mounted on an impenetrable ceiling, for example concrete ceiling, and with the cabling entering
from the sides of the product, there is no need for any ingress protection.
If the sounder base is mounted with the cabling entering from above (through the inner ceiling), there is a need for an ingress pro-
tection (type 4489).
