Installation
When the sounder/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/sounder
strobe
only
adopts
conduit
embedded. Its mounting method is shown in Fig. 3b.
