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.
¾The detector and the gas stove should be
placed in the same room.
¾The detector detecting natural gas or coal
gas should be mounted above 50cm from the
resources or the gas stove (Natural gas or coal
gas is light so it is gathered overhead in the
room). The detector detecting liquefied

petroleum gas should be mounted within 30cm
to the floor.
Fig. 2
¾The 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.
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. 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-.
3. Mounting
Mounting of C-9602LW is shown in Fig. 4.
a. Fix the bracket on the wall.
b. Align the groove in back of the detector to
the hook, press it down to fix.

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 monitored gas
density is over its preset value, 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 gas density goes below the preset
value, the detector will automatically stop audio
and visual signal and K1, K2 will be self-opened.
If, 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 alarms, please immediately
open the windows for ventilation 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
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. Each type of the detector can only detect
the kind of gas nominated on its label.
2. 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.
3. The detector can only control JJ or FCR
series solenoid coming with the detector. If
other models are to be used, please consult us.
4. The detector should be tested every half
year.
5. Coal gas detector mustn’t test by a lighter
but hydrogen in a bag. The distance from the
outlet to the detector should be more than
10cm.
6. Liquefied petroleum gas and natural gas
HTTP://GSTRU.RUE-MAIL: [email protected]

HTTP://WWW.HOMBI.RU
9
detector can be tested by a lighter. Put the
lighter near the sensor (over 10cm) press its
switch to turn it on and then blow off the flame.
The detector should alarm in about 10
seconds.
7. The detector will normally be a bit hot in
operation.
8. Never cut down the power of the detector.
9. If the detector has been stored with power
shut off for a long time, it will resume normal
work after more than 5 hours with power on.
