In accordance to the EN50291 standard.
When the alarm sounds, it must turn off within 6 seconds after moving the detector to a space with
a CO concentration below 40PPM.
The detector will automatically perform an error check.
BATTERY INFORMATION INDICATION:
The battery is checked automatically.
The green power LED will flash every 40 seconds for as long as the battery power is higher than
3.5 Volts. This means the battery capacity is sufficient. As soon as the battery power drops below
3.5 Volts, a beep tone will be emitted when the green LED flashes briefly. At that time, please
replace the batteries as soon as possible.
Use High Energy Alkaline batteries (3 x LR6 / 1.5V AA).
Remark: Rechargeable batteries are not suitable.
With both the supplied batteries and most A brand batteries on the market, it will take
approximately 7 years before the batteries run empty.
TESTING AND RESET:
Testing:
When the CO detector is working under normal conditions, the sensor and siren should be tested at
least every month by pressing the “TEST/RESET” button.
“ALARM” LEDs will blink. The detector will then emit 3 beeps while the red “ALARM” LED flashes 3
times. It means everything is in order.
If the sensor detects an error, the yellow “FAULT” LED will flash 2 times while 2 beep tones are
emitted.
Reset:
The alarm can sometimes activate because of environmental influences, for example due to smoke
with certain carbon monoxide concentrations or other chemical gases that are not life-threatening.
In this case, you can press the “TEST/RESET” button provided that the CO value is below 150PPM.
The alarm will stop and the detector immediately starts checking the gas again. If the concentration
is above 150PPM, it’ll be impossible to stop the alarm. The red LED continues flashing, but the
siren will stop for 5 minutes. If the concentration is still above 150PPM after those 5 minutes, the
alarm will continue.
ALARM DISPLAY AT ACTIVE ALARM:
When there’s an active alarm, the red “ALARM” LED will illuminate, 3 beep tones are emitted
continuously. When the carbon monoxide concentration drops below 40PPM, the alarm will stop.
