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):

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.)

VI. 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 Design of Automatic Fire Alarm System and
the Installation andAcceptance of Fire Alarm System.
A self-contained complete base is necessary during the installation of a detector. As shown in Fig.5, the
model, the external dimensions, the mounting hole diameter and the mounting hole spacing of the base
are DZ-912, Ф100mm×26.4mm (diameter×thickness), Ф4.5mm and 44.5mm～64.3mm respectively.

Wiring requirement:
It is proper to use RVS twisted pairs with a section area of equal to or larger than 1.0mm2 for the signal
buses L1 and L2.
Specific installation and debugging methods:
1. Make sure the type of the detector matches the type of the host machine of the fire alarm
control panel;
2. Use two M4 screws to fix the matched mounting base on the designated position via the
mounting holes C and D shown in Fig.6, as instructed in the construction drawing and make
sure the matched mounting base has been firmly installed.
3. Use a coder to make the detector coded according to the detector address on the construction
drawing.
4. Disconnect the power supply of the fire alarm control panel and connect the detector correctly
according to the construction drawing.
5. The lower edge of the detector base raised position aligned with the groove position, and then
the detector into the base, the detector clockwise until it locks into place the detector;
6. After all the products are installed and checked, connect the power supply of the fire alarm
control panel and conduct automatic login.
7. When automatic login is success, the red indicator of the detector will blink once about every 12
seconds, which suggests that the detector has begun to operate normally.
8. Finally conduct an alarm test for the detector through some special tools or direct smoke
blowing. After the detector gives a fire alarm, the indicator will remain lit and the fire alarm
control panel will simultaneously show corresponding alarm prompt information. After the alarm

test, reset the fire alarm control panel and restore to the monitoring status.

II. Precautions
1. A detecto
r
can not share an address with othe
r
equipment in a single bus circuit, o
r
else an
address conflict ma
y
occur.
2. Neve
r
dismount the protective cove
r
delivered with the detecto
r
too earl
y
afte
r
the field
installation and before the use of the detector, o
r
else the detecto
r
ma
y
be contaminated.
