II. Product features
It can realize electronic coding and rewrite the address via coder in situ.
Within a single-chip microcomputer, it can process the sampling data in real-time, save the
latest 144 historical data and realize a curve tracing for the field situation.
It has a temperature, humidity and dust accumulation drift compensation function and a sensor
fault detection function (fault reporting to fire alarm control panel).
Non-polarity, two-bus connection that ensures convenient installation and maintenance.
Designed with an upper cover and a lower cover and installed on an independent base, it can
be installed, debugged and maintained conveniently.
Built-in remote indicator output terminal, drive remote indicator lit when fire alarm
。

I. Product overview
A9030T point-type photoelectric smoke detector (Detector hereunder) is a
kind of photoelectric smoke detector. With an internal microprocessor, it
supports electronic coding and is accessed through a compatible fire alarm
control panel via a two-wire bus. The detector realizes real-time acquisition of
the in situ smoke concentration data and sends back the data to a fire alarm
control panel. It can also receive and execute the control commands given by
a fire alarm control panel.
The detector is suitable for such industrial and civil buildings that have a great
deal of smoke during fires but no smoke under normal circumstances, such
as restaurants, hotels, teaching buildings, office buildings, computer rooms,
communication machine rooms, libraries and archives. It is not suitable for
places with a great deal of retained dust and water mist, places where steam
and/or oil mist may be generated and places with retained smoke under
normal circumstances.

Definitions of terminals(non-polarity
two-wire system):
1 --Signal terminal (L1)
2 – Positive of remote indicator
3 --Signal terminal (L2)
4 – Negative of remote indicator
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.

3.
Remote Indicator connection: the positive and negative of remote indicator should respectively
connect on terminals 2 and 4,as shown in Fig.4.

4.
Coding address: As shown in Fig.5, 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.)
