2)
Wiring method: The detector is accessed through a compatible fire alarm control panel via a two-wire bus. It uses
non-polarity connection. The terminals L1 and L2 of the two-wire bus are connected with the terminals 1 and 3 of the
matched mounting base. Fig.3 is a schematic diagram of the connection between multiple detectors with a fire alarm
control panel.

Coding address: As shown in Fig.4, detector is accessed via the detector mounting base on the coder, non-polarity
connection is adopted for the terminals L1 and L2, set the coder with the coding function, select the correct address
number and press the RUN key to complete the address code setup. (Note: See the User’s Manual of the coder for the
detailed operation.)

Working mode configuration: Working mode can be set via coder according to different applications. When setting
the working mode,detector is accessed via the detector mounting base on the coder,
(see Fig. 4).
(Note: See the
User’s Manual of the coder for the detailed operation.)

Installation and debugging
Determine the location, mounting distance and numbers for mounting the detectors in the protection area according to
relevant provisions and regulations of the local codes.
A self-contained complete base is necessary during the installation of a detector. As shown in Fig.6, the model, the external
