Recommended Wiring
1.5mm2or above fire cable for 24VDC power line,
subject to local codes.
Installation
When surface mounted, the sounder strobe should
be placed 0.2m from the ceiling for normal space
height. When the conduit is embedded, the base
can be mounted on the back box. When the
conduit is surface mounted, the deep base should
be adopted. Knock the knockout hole, and connect
the conduit with it. The mounting hole spacing and
mounting direction are shown in Fig. 2. Mounting
method is shown in Fig. 3a and Fig. 4. The conduit
must be embedded when the shallow base is used,
as shown in Fig. 3b.
The base and the sounder strobe are twisted
together. When mounting, remove the sounder
strobe, thread cables through the cable entry in the
base and connect with corresponding terminals,
then twist the sounder strobe onto the base.
