IV Mounting and Wiring
1. Position of Mounting
The detector is wall-mounted. Mounting
position (Fig. 2) depends on where the gas
stove is.
There are still some principles to follow.
The detector and the gas stove should be
placed in the same room.
The detector should be mounted above
50cm from the sources or the gas stove (Coal
gas is light so it is gathered overhead in the
room).

The detector should be within 1.5m ~4m
to the gas resource or the gas stove.
To correctly use the detector and avoid any
possible fault, please do not mount the
detector at following locations:
a. Where affected by exhaust, steam or
oil smoke from the stove.
b. Where near strong airflow, such as
air-inlets, fans, doors, etc.

5
c. Where near bathroom or places with a
lot of vapor.
d. Rooms for boiling water and places
where power is cut at night.
e. Where temperature is below -10℃or
over 50℃or outdoors.
f. Where explosion-proof measures are
required.
g. Where the detector is partitioned with
the gas devices.
2. Connecting output contacts
The cover near the bottom is opened by
pressing it with strong force. Then terminals for
connections can be seen. Those terminals are
shown in Fig. 3.
Fig. 3
K1, K2: Volt-free normally open contact, it is
closed when alarming.
V+, V-: Connects with pipe solenoid or
mechanical hand. When alarming for 3s~7s,
there is a forward 12V pulse voltage between
V+ and V-.
Put cables through the conduit under the cover,
and connect them with terminals. Note：The
conduits are located under the top cover. They
are not opened before leaving the factory.

6
Therefore, it should be opened when
connecting cables.
3. Mounting
Two mounting ways of C-9602LW-NG detector
are shown in Fig. 4.

a. Hang the bracket on the wall.
b. Align the groove in back of thedetector to the
hook, press it down to fix.

a) 将金属挂板放在产品背面相应凹槽内（出厂已经放好）；
b) 在墙上安装一个螺钉，螺钉头部露出墙面6mm左右；
c) 将挂板葫芦形挂孔挂在螺钉上即可。

a. Put the bracket in the groove of the detector
(by default before leaving the factory).
b. Install a screw on the wall with head about
6mm above the wall surface.
c. Hang the detector with the bracket on the
wall.
4. Wiring
0.5mm2or above Fire-resistant copper core
cable for V+ and V-.
1.0mm2or above Fire-resistant copper core
cable for K1 and K2.
V Application
1. Applying power supply to the detector
after wiring and checking, the green LED
flashes 3~6 minutes for warm-up, and then it
will light constantly for normal monitoring.
2. Alarming: When the volume ratio of coal
gas to be monitored is above the alarm set
point, the detector gives quick intermittent
"Tick" sound with red LED quick flashing and
K1 and K2 are closed. After alarming for 3s～7s,
the detector will output a forward pulse current
to close solenoid. When the volume ratio of coal
gas goes below the alarm set point, the
detector will automatically stop audible and
visual signal and K1, K2 will be self-opened. If,

8
at this time, the solenoid has been closed, it will
be kept closed, and you will have to pull it open
manually.
3. Fire Alarm Treatment
When the detector goes into alarm, please
immediately open the windows for ventilation;
Cut gas source if there isn’t solenoid valve; Put
out any fire; do not make new fires; Avoid
switching on or off any electric appliance, find
out the reason of leaking and call professional
engineers.

VII Maintenance
1. Avoid using much hair tonic, pesticide,
paint, alcohol, diluents etc near the detector, to

9
avoid affecting normal monitoring of the sensor.
2. In case of fault, never remove or open the
detector by yourselves. Inform our company or
our local office for repair.
VIII Cautions
1. Don't install the detector at locations with
high temperature (near stoves) or too much oil
smoke (near kitchen ventilator); Keep
environment around the detector clean.
2. Please contact local gas company and ask
a professional engineer to install a solenoid
valve on the gas pipeline if it is required. The
detector can only control JJ or FCR series
solenoid coming with the detector. If other
models are to be used, please consult us.
3. The detector should be tested every half
year. Coal gas detector can’t be tested by a
lighter but hydrogen in a bag. The distance
from the outlet to the detector should be more
than 10cm.
4. The detector will be normal with a bit hot in
operation.
5. Never cut down the power of the detector.
6. After having been stored without power, the

10
detector will not work normally until it is
powered for a period.
