2. Standby status the LCD show as below:
3. When the carbon monoxide concentration level reach
30ppm,the LCD begin the display the concentration.
4. The sensor will automatic check the breakdown when
it is working ,if the sensor breakdown ,the detector
yellow indicator will lighting and the buzzer with the
ceaseless sound ‘di’, and the LCD display as below:
Reference points calibration
1. The sensor use in the detector, it is the precision
device. When it was strongly shocked or knocked, the
sensor ’s reference points will change, and it will effect
the detected correction. In this situation need to do
reference points calibration.
2. Reference points calibration’s operating guide:
A.Stop supply the power, if the detector have the standby
battery, take it out.
B.Press the testing button and supply power to the
detector.
C.After 4s sounds DEE and release the button, the
detector enter calibration status, the green LED light
ash quickly, and the LCD display as below:
D.After 1 min, the calibration is nish, the detector enter
working status.
3.Cautions for reference points calibration
A.Before reference points calibration, assure the product
have been burned in more than 24 hours.
B.Doing the reference points calibration should be in the
clean air.
Warming condition and deal
When the concentration of carbon monoxide in the air
have reach or access he alarm default concentration
level, the detector will automatic enter the continual
alarm status, now should do:
1. Turn off the pile valve immediately.
2. Open the windows to assure the room good ventilation
3. Turn off all re seat,avoid anything that might sparking.
4. Avoid turn on/off all kind equipment.
5. Check the gas leakage reason, inform all related
departments and the related professional person to
deal immediately. If found it is false alarm, the user
need to check the installing location is properly or not.
Lighting information
Red LED light ash means the carbon monoxide leaks
Green LED light ash means it is warm-up status
Green LED lighting means it is working status
Yellow LED lighting means the detector inside breakdown
Breakdown analysis and remove
Breakdown
phenomenon reason analysis remove way
after supply power,
the detector keep
warm-up status
1. long time not supply power 1.supply power burn-in 24
hours
2. warm-up period use the gas
to test
2.prohibit use the gas to test
during warm-up period
3. the sensor reference points

Yellow LED lighting,
the buzzer keep sound
the sensor breakdown contact the supplier to
maintain
the magnetic valve
can't turn off the wiring connect wrong follow the manual to connect
the wiring correctly
Harm of the carbon monoxide
The carbon monoxide in the air, it with narcosis effect
for the human central nervous system, the serious one
might lead asphyxia even dead. When the human body
inhale related concentration CO and time, it will have the
symptoms as below:
50ppm it is the maximum concentration that the health
adult can stand during 8 hours.
200ppm after 2-3hours, slight headache, feeble
400ppm frontal headache during 1-2 hours, after 3 hours,
threatening the life.
800ppm during 45 minutes, dizzy, nausea, spasm,
anesthesia during 2 hours, die during 2-3hours
1600ppm during 20 minutes, headache, dizzy, nausea,
die during 2hours.
3200ppm during 5-10 minutes, headache, dizzy, nausea,
die during 30minutes.
6400ppm during 1-3 minutes, headache, dizzy, nausea,
die during5-10minutes.
12800ppm die during 1-2 minutes.
Cautions
1. This product is the carbon monoxide detector,
can’t use for testing the natural gas, LPG, etc.
2. This products cant be shook strong or knocked,
otherwise it might lead the product can’t work
correctly.
3. This product must have the correct wiring
connection and the correct power supply.
4. This product need to follow the manual to do
the scheduled maintenance.
5. Please use the dust collector to clean the dust
on the detector’s surface 1 time per month.
6. Don’t use the detergent or solvent to wipe the s
ensor, the chemicals might destroy permanent or
temporary pollute the sensor.
7. Avoid sparge the air freshener, hair gel, paint or
other sprays near the sensor.
8. The detector’s life is not unlimited, should ask
the professional person to test 1 time each half
year, once nd the detector doesn’t work, need to
maintain or change the new one.
9. This product can reduce the accident happening,
but not assure everything. For your safe, except
using this product correctly, you need to keep
caution and strengthen the safety consciousness.
