Instruction Manual of ATL-930 Addressable Smoke Detector
------ Please read this Manual carefully before installing and using the product. -----
I. Product overview
ATL-930 Addressable 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 of ATL-MN300 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.
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.

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.)

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 GB50116-98 Code for Design of Automatic Fire Alarm
System and GB50166-2007 Code for Installation and Acceptance 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-910, 100mm×22mm (diameter×thickness), 5mm and 56mm～64mm respectively.

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.
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.5, 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. Place the indicator at position A of the detector (see Fig.1) and position B of the base (see
Fig.5), align them with each other, insert the detector into the base and turn the detector
clockwise until it is firmly locked.
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.

VII. Precautions
1. A detector can not share an address with other equipment in a single bus circuit, or else an
address conflict may occur.
2. 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.
3. The protection area and quantity of the detectors should comply with relevant provisions in
GB50116-98 Code for Design of Automatic Fire Alarm System and GB50166-2007 Code for
Installation and Acceptance of Fire Alarm System.
VIII. 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.
1. For a detector, at least semi-annual tests should be done according to related provisions of
GB50166-2007 Code for Installation and Acceptance of Fire Alarm System; for a detector that has
been installed and used, it is recommended to have it cleaned and maintained once every two
years.
2. 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.
3. If a detector fails due to a material defect or a manufacturing process defect under normal
conditions of use in one year following the date of its delivery, we shall repair or replace it for free.
However, the faults of the detector due to artificial damage, improper use, or authorized adjustment,
reconstruction or disassembly are not covered in the guarantee and we shall assume no
responsibilities for any the consequence thereby caused.
4. We may provide paid repair service for products with any faults beyond the guarantee range. If you
have such products that need repair, please contact us. When sending such a product to us for
repair, you are expected to provide some important information about the product, such as the
phenomenon and possible cause of the product fault, so that we can find out the cause of the fault
in the shortest time and so the information may be used as a reference in our future product
development and improvement.
