4. Address coding: When a horn/strobe is coded, it is unnecessary to disassemble the wire connecting it
with the host machine; online coding may be done. The specific method is as follows: Open the cover
of the coding setup window, insert the output plug (a four-pin connector) of the coder into the address
coding socket (the socket J2 in Fig.2) of the horn/strobe, set the coder with the coding function,
compile the correct address code and press the RUN key to complete the address coding. (Note: See
the User’s Manual of the coder for detailed operation information.)
Warning:
It is necessary to have “online coding” done when the system is powered off
or related equipment may be damaged.
5.
Usage: Do not connect the power supply until the address of the horn/strobe has been set and
confirmed and the fire alarm control panel has been properly connected. After the fire alarm control
panel is successfully reset, the red status indicator (see Fig.3 for its location) of the horn/strobe will
blink. After the horn/strobe receives an operation signal, the status indicator will remain lit and the
horn/strobe will give both horn/strobe alarm signals. After the system is muted or reset, the horn/strobe
will stop outputting horn/strobe alarm signals and the status indicator will start to blink again.
VI. Installation and debugging
A special base is necessary during the installation of a horn/strobe. As shown in Fig.4, the external
dimensions of the special base are 142×84×10mm (L×B×H). The horn/strobe is subject to a four-wire
non-polarity connection: Terminals 1 and 2 are respectively connected with the ter24V and GND
of the DC power supply terminals 3 and 4 are respectively connected with the terminals L1 and L2 of the
signal bus of the fire alarm control panel. See Fig.5.

Specific installation and debugging methods:
1.
Use two M4 screws to fix the matched mounting base on the designated position via the mounting holes
shown in Fig.4 (the installation may be done horizontally or vertically. Choose any two of the six mounting
holes for installation) as instructed in the construction drawing and make sure the matched mounting base
has been firmly installed.
2.
Disconnect the power supply of the fire alarm control panel and connect all the bases correctly in the way
shown in Fig.5, which is a construction drawing.
Note: When there are a lot of horns/strobes in a system, it is necessary to consider the loading capacity of
the power supply of the fire alarm control panel. An external DC24V auxiliary power supply might be
necessary at this time. Please follow the construction design drawings.
3.
Make sure the type of the horn/strobe matches the type given on the construction drawings. Use a coder to
code the horn/strobe according to the address code marked on the construction drawings.
