Carbon Monoxide detector operating manual
Product Overview
This product is the high stable Carbon monoxide detector
(below abbr as the detector), it use for detecting the
leakage of the carbon monoxide. It is made of the most
advanced electrochemistry carbon monoxide sensor, it
with high stability, sensitivity drift small such character.
This product use the backlit digital LCD to display the
alarm level. The detector can operates with the voltage
between AC110-230V, after installing with the standby
battery function. When the detector detects the carbon
monoxide leaks and the thickness reach the default
alarm level, the detector red LED ash and sounds. This
product suits for the all the places that might produce the
carbon monoxide.

Wiring installing instruction
All the wiring installing need to follow the national or the
local law and standard. The thickness of the wire stylet
need to be properly. the improperly connection may lead
the detector does not alarm when the carbon monoxide
leak.
Product Installing
1. This product suits for plug type mounting and wall
mounting, choose the properly place, generally on
the ceiling above where have the carbon monoxide,
the distance is about 2m.
2. Static the installing support x on the ceiling, and
insert the detector on the installing support. Or choose
the place where there is the plug board, and plug the
detector on the plug board directly.
3. Home usage detector need to avoid installing near the
gas stove, to avoid the detector be heated by the re
from the stove; avoid install in the place where has
strong smoke, it might lead false alarm or effect the
detector sensor’s sensitivity; avoid install near the
ventilating fans, windows and bathroom these high air
ow areas.
4. The wiring connects need to follow the installing
diagram, all the wiring need to follows the national and
local laws, standards. The wiring thickness should be
properly, the wiring connects the detector and the
other assisted device should be marked colors, to
avoid connect wrongly. The improperly wiring
connection might lead the detector don’t alarm
correctly when it detect the leakage of the carbon
monoxide.
Operating instruction
1. Supply the detector with power. The detector enter
the auto-check status, the green LED, red LED, yellow
LED indicator ash 1 time at the same time, the buzzer
sounds ‘di’ 1 time. Then the detector enter the warm-up
status, LCD symbol display in turn, warm up need
about 60s, the LCD back light close, LCD display the
power supply and check the gas’ chemical symbol, it
means the detector enter monitoring status. Warm-up
period prohibit use the gas to test. When the outside
AC power stop to supply, the detector will automatic
change the standby battery to supply. When the battery
volume is too low, LCD will display the low battery
volume mark, the green indicator will ash 1 time every
12s,and with the buzzer sounds 1 ‘di’.

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

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
