external wire S, G; 1.0mm
terminals, subject to local codes.

Installation

When the sounder strobe is surface mounted, it should
be placed 0.2m from the ceiling for normal space height.
When conduit is embedded, the base can be mounted on the
electrical box. When conduit is surface mounted, the deep
base should be adopted. Knock the knock-off hole, then
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. When the shallow base is
required, the sounder strobe only adopts conduit embedded.
Its mounting method is shown in Fig. 3b.
The base and the sounder strobe are twisted together.
When mounting, remove the sounder strobe, thread cables
through cable entry in the base and connect with
corresponding terminals, then twist the sounder strobe onto
the base.
If the sounder strobe is required anti-removal, knock
down the arch knock-off hole as shown in Fig. 1 and fix it with
ST2.9×6.5 tapping screws (in this case, it must be removed
by a special tool).
