A9036T Addressable Optical Smoke and Heat Multisensor Detector
Read through these instructions before using this device to ensure correct installation and use!
1. Product overview
The A9036T point composite smoke and temperature
fire detector (hereinafter referred to as the detector) is
composed of a smoke sensor and dual heat sensors.
It not only has the performance of photoelectric smoke
fire detector, but also has the performance of heat detector.
The detector is made of non-polar two bus, which can be
used with fire alarm control panel produced by our
company.
2. Product features
Dual heat sensors
The low profile design of the Optical/Heat Multisensor detector Detector is sleek and evolutionary, with a 360° LED
indicator which illuminates red when in alarm.
Non-polarity, two-bus connection that ensures convenient installation and maintenance.
It can realize electronic coding and rewrite the address via coder in site.
Within a single-chip MCU, it can realize real-time data acquisition and processing, 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).
A sophisticated dynamic algorithm, providing transient rejection and compensation for drift whilst maintaining
accurate sensitivity.
Reference to Table 1, the detector has five modes. Working mode can be set with a coder.

Definitions of terminals(non-polarity
two-wire system):
1 --Signal terminal (L1)
3 --Signal terminal (L2)
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) 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.)

4) 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.)
6. 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

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.
Fig.5
Wiring requirement:
It is proper to use RVS twisted pairs with a section area of equal to or larger than 1.0mm2for the signal buses L1 and L2.
7. Specific installation and debugging methods:
Make sure the type of the detector matches the type of the host machine of the fire alarm control panel;
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.
Use a coder to make the detector coded according to the detector address on the construction drawing.
Disconnect the power supply of the fire alarm control panel and connect the detector correctly according to the
construction drawing.
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.
After all the products are installed and checked, connect the power supply of the fire alarm control panel and conduct
automatic login.
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.
Finally conduct an alarm test for the detector through some special tools. After the detector gives a fire alarm, the
indicator will remain lit and the fire alarm control panel will simultaneously give corresponding alarm prompt
information. After the alarm test, reset the fire alarm control panel and restore to the monitoring status.
8. Precautions
A detector can not share an address with other equipment in a single bus circuit, or else an address conflict may occur.
Never dismount the protective cover delivered with the detector too early after the field installation and before the use
of the detector, or else the detector may be contaminated.
The protection area and quantity of the detectors should comply with relevant provisions and regulations of the local
codes.
9. Maintenance
Warning: Before conducting maintenance for detectors, inform the related management department that the
monitoring will be stopped temporarily when the system maintenance. Meanwhile, disable the logic control function of
the area or system to be maintained to avoid unnecessary alarm linkage. After the test, inform the management
department to restore the normal functions of the system.
For a detector, at least semi-annual tests should be done according to related provisions and regulations
of the local codes; for a detector that has been installed and used, it is recommended to have it cleaned and
maintained once every two years.
Operating environment has a great influence on the performance of the detector. If the detector is installed
and used in a place where its normal use is easily affected by dust, high wind speed and other factors, its
maintenance period should be shortened.
