Description

I-9403 Intelligent Sounder Strobe (the sounder strobe) is
an audible and visual alarm device installed in field,
which can be activated by fire alarm control panel in fire

The sounder strobe can use together with a 25.5mm
high shallow base or a 40mm high deep base. Deep
base is used if there is no special statement in this
manual.

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 should be
mounted on the back box. When 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 of the
sounder strobe with a deep base 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.

If the sounder strobe is required to be tamper-proof,
knock down the knockout as shown in Fig. 1 and fix it
with ST2.9×6.5 self-tapping screws (in this case, it can
only be removed by a cross screwdriver).

Application

Address, tone, programming method, working mode,
consumption mode can be set through P-9910B
