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 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-912,

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.
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 the
Design of Automatic Fire Alarm System
and the
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 the
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.
