VI. Product installation and adjustment
According to relevant provisions and requirements in the China national standards GB 50116-2013
Code for design of automatic fire alarm systems and GB 50166-2007 Code for installation and
acceptance of automatic fire alarm systems, ensure proper installation positions, spacing and quantity of
detectors in the protected area.
Each detector shall be installed using a matched base. The matched base is shown in Fig. 5, its model
number is DZ-910, its outside dimensions are Ф100 mm × 22 mm (diameter × thickness), its fixing hole
diameter is Ф4.5 mm and its fixing hole spacing is 44-65 mm.
Fig. 5
Wiring requirements:
Signal wires L1 and L2 should use RVS-type double twisted wire, with a cross-section area ≥ 1.0 mm

.
The specific installation and adjustment methods are as follows:
1.
Confirm that the detector type matches with the controller main unit type;
2.
Fix a matched base to the specified position through fixing holes C and D shown in Fig. 5 using two
M4 screws according to the construction drawing and confirm that the base has been securely
installed;
3.
Encode a detector using the encoder according to the detector address number marked in the
construction drawing;
4.
Cut off the power supply for the controller and connect the detector correctly according to the
construction drawing;
5.
Align the indicator lamp of the detector (place A shown in Fig. 1) with the installation mark on the
base (place B shown in Fig. 5) and then insert the detector into the base and rotate the detector
clockwise until the detector is locked in position;
6.
After all products are installed and they are confirmed to be properly fitted, turn on the power supply
for the controller to carry out automatic login operation;
7.
After normal automatic login, the red indicator lamp of each detector flashes once every 12 seconds,
indicating that the detector has started operating normally;
8.
Finally, conduct a detector alarm test using the method of directly blowing by the hot air cylinder and
the direct smoke blowing method respectively. After the detector gives an alarm, the indicator lamp
will remain on and the controller will give a corresponding alarm prompt message. (
Note: After the
test of one kind of alarm is successful, only should the controller be reset is it possible to
conduct a test of another kind of alarm.
) Therefore, once the test is complete, the controller must
be recovered to ensure that the detector returns to the monitoring state.
VII. Points for attention
1.
In the same bus loop, a detector cannot use an address the same as that of another device to avoid
a conflict of address.
2.
Before use after the onsite installation is over, do not remove the protecting cover attached to a
detector too early to prevent the detector from becoming contaminated.

3.
The detector protected area and the quantity of installed detectors shall meet relevant provisions in
the China national standards GB 50116-2013 Code for design of automatic fire alarm systems and GB
50166-2007 Code for installation and acceptance of automatic fire alarm systems.
VIII.
Maintenance and care
Warning: Before maintenance of detectors, the relevant management department shall be
notified that the system will be maintained, thus the monitoring will be stopped temporarily. In
addition, the logic control function for the area or system to be maintained shall be cut off to
avoid unnecessary alarm interlocking. Once the test is complete, the relevant management
department shall be notified to recover the normal state of the system.
1.
According to the requirements in the China national standard GB 50166-2007 Code for installation
and acceptance of automatic fire alarm systems, the detectors shall be tested at least once every
six months; it is recommended that all detectors which have been installed and are under use
should be cleaned and maintained once every two years.
2.
Operating environment has a huge influence on the performance of a detector; for a detector
installed and used in an environment where there is likely to be dust and high wind speeds, etc.,
which affect normal operation, its maintenance and care period shall be shortened.
3.
If a detector normally used according to the specified requirements fails due to a defect of materials
or manufacturing technique within one year from the day when the product leaves the factory,
Shenzhen Fanhai Sanjiang Electronics Co., Ltd. will be responsible for free repair or replacement.
Any failure caused by artificial damage, improper use or unauthorized adjustment, alteration or
dismantling is not covered by the warranty scope, and our company will assume no responsibility for
all consequences caused by it.
4.
Our company is responsible for paid repair of products not covered by the warranty scope; if you
need a repair service, please contact us. Moreover, we will need to obtain some important
information about the product you need to be repaired, e.g., product failure status and possible
causes, so that we can find the problem in the shortest time. We also hope that a reference will be
provided to us for our future product development and improvement.
