CARBON MONOXIDE
DETECTOR
MANUAL
This product is an intelligent carbon monoxide detector with voice
prompt (hereinafter referred to as detector).Using CPU control,
the detector can display the carbon monoxide concentration, ring
the siren when the detector got triggered. It works stably. It has
beautiful appearance and you do not need to debug it . It can be
widely used for fire safety alarm monitoring in residential,
shopping malls, hotels and other places. The detector has a
buzzer with a high decibels sound after the alarm.
Functional Characteristics
1. Adopt advanced planar semiconductor gas sensor
2. Can display the carbon monoxide concentration
3. Microprocessor intelligent control
4. Sensor fault detection automatically

Installation
1. Suitable installation is 0.3-1.0m lower than ceiling and at least
1.5M far from the gas source radius.
Please do not install the detector in this area;
The vertical position of Ceiling & gas source
is the center, Circle with radius of 1.5m.
Detector
Gas stove
2. Fix the board on the selected place by screw, insert the
detector and revolve it, then check whether it is firm or not.
3. For h
ome installation should pay attention, please do not install
the detector near the gas stove, to avoid detector bake by the
stove flame
, do not install in the place with large lampblack, to
avoid wrong alarm or
cause the detector air intake not smooth,
which greatly affect to sensibility of the detector, please do not
fix near the ventilators, windows, doors, shower room with
much source of steam.
Test
After the detector is installed, you use a lighted cigarette at a
distance from the gas convection window 5cm, then blow same
smoke to the alarm inlet to check carbon monoxide alarm. Due
to the inherent characteristics of the sensor, please don't release
plenty of gas with high density to test the detector and do not
frequently or long time test the detector which might cause the
damage of detector sensitive material and the fall of the detector
sensitivity greatly, all would result i fault alarm. When the
concentration of carbon monoxide below the set value, the
detector will automatically stop to alarm, and be restored to the
monitoring state.
Alarm Processing
When the concentration of carbon monoxide in air reaches or
exceeds the alarm set value , the detector will enter into continuous
alarm state. Then please follow the below steps.
1. close the pipe fixed door immediately
2. open the window at once to ventilate the room
3. extinguish all the fire sources and avoid to use everything that
can produce sparks
4. avoid switching all kinds of electrical appliances
5. check the causes of gas leakage and notify relevant departments
and relevant professional personnel in time to deal with it. If it is
false alarm, the user should check the location of the detector is
fixed suitable or not.

Install Environment
Any electrical products have the using environment requirement,
this product installation should pay extra attention following items:
1.Avoid the product to touch high temperature water vapor, long
time influenced of lampblack; if could not avoid, should install
exhaust fan, ventilator etc. Equipment near to the detector.
2.Avoid to install in high humidity environment; that means the
place with plenty of water vapor, water.
3.Avoid to install in high or low temperature, should be above
55℃or under -20℃.
4.Please be far always from following gases: organic silicon vapor,
formaldehyde, methyl-benzene, acetic acid, hydrogen sulfide, etc
which mainly produced by house decoration, decoration material,
such as binder, wall painting, hairspray, silicon rubber etc. These
gases would cause the detector damage, not possible to recovery,
and cause the detector give fault alarm. In addition high density
formaldehyde vapor would cause the fault alarm.
Matters Need Attention
1. The product must work with correct connection and right power
supplier, the detector could not work normally no matter
what ‘s reason caused the power off,.
2. Please take off the blister in time after the detector keeping
work for 24 hours powering on.
3. The product should keep periodic maintenance according to
the user manual.
4. The detector could not work without life time limit,our
recommended validity life is 3 year, it should be test every
half year, and you should repair or change after find it invalid.
5. The product could not use high density(>100% LEL）gas to
test, otherwise it might reduce the sensor sensitivity, and
cause the sensor could not work normally.
6. The product could reduce the accident, but could not make
sure a hundred percent safe. For your safety, please keep
precaution and enhance safety consciousness in daily life,
besides using our products correctly.
Operation Description
1. Power up
Connect the power, the power indicator light up, the detector
enter into the preheating state, and the digital display shows 3
minutes countdown.
2. Normal state
The preheating state be completed, when the green power
indicator light is always on, the detector enters the normal
working state.
3. Alarm state
When the detector detects the concentration of carbon
monoxide exceeding 200PPM, it will trigger the buzzer, and the
flashing lamp. At this time, you should immediately turn off the
gas valve, open the doors & windows to ventilate the room
and notify the relevant departments and relevant professional
treatment to deal with it. When the concentration is restored to
normal, the detector automatically returns to normal state . If it
is false alarm, the user should check the location of the detector
is fixed suitable or not.
4.Test state
In the normal working state, press the test key 1 times, the
detector enters into the self-examination program, the buzzer
rings, and the alarm light flashes.
