This product is an indoor combustion gas detector with high
stability , hereinafter called detector, used for combustion gas
leak detection. It uses highly stable semiconductor gas sensor
with features of stable performance and low drift of
sensitivity. When it senses combustion gas leak that reaches
the set alarm level, it will give out alarm sound with red LED
flashing. The detector is applied in indoor places where
combustion gas leaks possibly happen.

INSTALLATION
1. First identify your gas heavier or lighter than air.
Heavier gases: LPG etc. Lighter gases: natural gas, marsh
gas, artificial coal gas etc.
2. Choose a suitable installing position according to gas
specific gravity. Detecting heavier gases, installation
height 0.3-1.0m from floor , semi-diameter to gas source
<1.5m; Detecting lighter gases, installation height 0.3-
1.0m from ceiling, semi-diameter to gas source < 1.5m
(refer to the following image).

3. Fix the attached base into a wall firmly with screws
and hang the detector.
4. Do not make it close to gas stoves when installing at home
in case it is roasted by flame. Neither places with heavy oil
or smoke that may cause false alarms or block the gas
convection holes and influence the detector sensitivity.
Also it is can not be installed near to exhaust fans,
windows, doors, and places with great vapor in bathrooms.
5. Connect the wires correctly according to the wire harness

操作说明
1、功能跳线设置
1) 、PULSE 跳线：脉冲调节跳线，通过脉冲计数的
调节可改变探测的灵敏度和抗射频干扰能力。
选择 1&2 ：为一级脉冲，探测灵敏度较高，有 较好
的抗射频干扰能力，适合一般的环境；
选 择2&3： 为 二 级 脉 冲 ， 探 测 灵 敏 度 高 ， 抗 射 频 干 扰
能力更强，适合射频干扰严重的环境；
断 开 ： 为 三 级 脉 冲 ， 探 测 灵 敏 度 偏 低 ， 具 有 及 高 的
抗射频干扰能力，适合射频干扰非常严重的环境。
2） 、RELAY跳 线 ：NC/NO选 择 跳 线 ， 用 于 设 置 报 警 输
出 状 态 ， 可 根 据 不 同 类 型 主 机 的 规 格 要 求 选 择 不 同
的输出状态，
选择1&2：为N.O.（常开状态)；
选择2&3：为N.C.(常闭状态) ；
出厂设置为2&3 N.C.(常闭状态)。
3）、LED 跳线：用于控制LED指示灯，不影响探测器
正常工作。
选择1&2：开启LED指示灯；
选择2&3：关闭LED指示灯；
为了增强探测器的隐蔽性，测试完毕后可关闭LED指
示灯。
2、步行测试
接 通12V直流电源，LED指 示 灯 亮 ， 探 测 器 进 入
自 检 状 态 ， 自 检 时 间 约60秒 ，LED指 示 灯 灭 时 表 示 探
测器进入正常监测状态。

instructions. All wiring and installation must accord with
the National and Local laws and criteria. Improper
connection will cause the detector not alarm while gas
leaking.
OPERATION INSTRUCTION
1. WIRING OF AC TYPE DETECTORS
1.1 For an AC type stand alone detector, it will work normally
just by plug-in.
1.2 For detectors with outputs, a 5-PIN wire harness is
attached in the gift box.
First connect the wires as per the wire harness connection
instruction and insert the wire harness connector into the
interface in the detector reverse before plug-in.
2. WIRING OF DC TYPE DETECTORS
A 5-PIN wire harness is attached in the gift box. First
connect the wires as per the wire harness connection
instruction. Then insert the wire harness connector into
the interface in the detector reverse.
3. FUNCTION
3.1 Connecting the power, the power LED constant green on.
After the buzzer gives out a Di sound, the circuit enters
into warm-up state. The red LED and yellow LED flash
alternately during warm-up and stop in about 3 minutes,
which indicates that the detector enters into normal
working state. Test is forbidden during warm-up time.
3.2 When any combustion gas leak happens and reaches the
alarm level, the alarm LED flashes red and meanwhile the
buzzer gives out “Di...Di” sound. If the detector has
output function, the relay output will be activated or pulse
signal will be sent out to shut off the connected solenoid
valves .
3.3 If an inside sensor failure happens, the yellow LED
constant on and the buzzer long beeps. Switch off the
power and contact your dealer for maintenance. Do not
take the detector apart privately to prevent electrical
shocks.
4. TESTING
4.1 The detector has a self-test button for checking if the LEDs
and the buzzer work normally. Pressing the test button, the
red and yellow LEDs flash alternately and the buzzer gives
out alarm sound and the output is activated if with the
function.
4.2 It is forbidden to test with a lighter directly toward the gas
convection holes. This will cause damage to the inside
sensor. Instead, gather the gas from the lighter into an
empty plastic mineral water bottle and release the
gathered gas toward the gas convection holes for testing.

ALARM TREATMENTS
FAILURE REASONS & SOLUTIONS
When the concentration of natural gas or LPG in ambient
air reaches or exceeds the alarm level, the detector will enter
into constant alarm state. Below treatments are advised:
1. Shut off pipe valves.
2. Do not plug or unplug electrical appliances.
3. Open windows to circulate air.
4. Inspect the gas leak reason and notify related departments
in time to deal with the leak by professionals. If it turns out
a false alarm, check if the installation position is improper.
Combustion Gas Detector Manual
1
1. The detector is for combustion gases detection. It can not be
used to test CO etc. poisonous gases.
2. Correct power supply must be provided and the wires
must be connected right. It can not work without normal
power supply.
3. Mild heat-up in housing surface is normal at working time.
4. Do maintenance as per this manual Periodically.
5. Vacuum the dirt in the detector surface every month.
6. Do not use cleansers or solvents to clean the detector.
Chemicals may cause permanent damage or transient
pollution to the sensor.
7. Do not spray air-freshers, hair gels, paints or other
aerosols near the detector.
8. To assure the detector sensitivity, the detector should be
inspected by a profession every year. If it fails to work,
repair or replace the detector asap.
9. The service life of the detector semiconductor gas sensor is
5 years. Replace the detector immediately when the service
life expires.
10. The detector can reduce accidents happening, but can
not guarantee a hundred percent safety. For your safety,
besides proper usage of the detector, pay attention to
build up safety conscious and take preventive measures
in daily life.
