5. Operating characteristics
I. Normal operation
The detector will enter normal operation within 20 to 30 seconds after powering
up. The Power indicator flashes every 45 seconds. When there is CO in the air,
the Power indicator flashed every 30 seconds. The Fault indicator and Alarm
indicator are off.
High or low temperatures, high levels of humidity, heavy jolts or falls may harm
the digital display.
IMPORTANT: This carbon monoxide detector is designed for indoor use only.
Do not expose to rain or moisture. Do not submerge the device in liquid, as this
poses a risk of electrocution or malfunction.
II. Alarm
The alarm response time of the detector complies with EN50291. The alarm
won’t stop until CO concentration is lower than 40PPM. Put the detector in
clean air, the alarm will terminate automatically in 6 minutes, or you can quit
alarm condition by pressing and holding the TEST button for 1 to 3 seconds.
Important
:
When you hear successive beeps, it means high concentration of CO. You and all
the personnel shall leave the dangerous site at once and seek help.
III. Low CO concentration warning
In daily life, low levels of carbon monoxide can often occur. For example,
cigarette smoking, burning candle and gas-burning appliances can produce low
concentrations of CO. Although it may do no harm to normal people, prolonged
exposure to low levels of CO can impair the health of vulnerable groups such
as children, pregnant women, elderly or patients. This warning is to help these
people avoid prolonged exposure to low levels of CO. If you press and hold the
TEST button and still hear beeps, the CO concentration may be more than 200
PPM. In this case, you cannot silence the alarm. When the detector is in alarm
silence condition, press and hold the TEST button until you hear beeps, then it
will recover alarm condition.
IMPORTANT: When sanding, stripping, wallpapering, or using adhesives/aerosols,
remove the CO detector. This is to prevent damage to the sensor.
6. Fault warnings and handling
I. Sensor fault warning and handling
If there is fault in the sensor or circuit, fault warning will be given within 3 min-
utes. Fault warning will be made at least once every minute until the fault is elim-
inated. When fault warning is given, there may be open circuit or short circuit
in the sensor. Or there may be electronic damage. Volatile gas like ethyl alcohol
may affect the sensor and cause temporary fault. In this case, please replace the
product with a new one. Then power off the damaged unit and put it in clean
air for 24 hours, and it will return to normal. If the unit can’t recover after being
placed in clean air for 24 hours, that means permanent damage.
Warning:
When the alarm is damaged permanently, please stop using it. Don’t repair it
jourself or send to the service point that is not authorized by the manufacturer.
II. Low battery warning and handling
When the detector is in normal operation, battery capacity is checked every
minute. When the voltage is less than 3.6V, low battery warning will be given,
the LCD display will show condition D. When low battery warning commenc-
es, batteries are only capable of giving low battery warning for one month, or
giving alarm warning for a few minutes. Replace the AA/LR6 batteries as soon as
possible.
Remove the PIN from the mounting plate buckle,
Remove the old batteries, and insert the new
batteries. Test the device accordingly before fixing
it back on the mounting plate.
