Standby
In the standby mode, the CO level (if this is lower than 20 ppm it will display 0) and the room
temperature are shown, in an alternating manner. If the CO level exceeds 20 ppm, only the CO
level is displayed. This detector is equipped with a night mode, which means that the standby LED
is automatically switched off in dark areas.
Alarm
If the CO level in the room is too high, the carbon monoxide detector switches to the alarm mode
according to the scheme below.
•
030 – 049 PPM: Alarm signal after 120 minutes
•
050 – 099 PPM: Alarm signal after 60 - 90 minutes
•
100 – 299 PPM: Alarm signal after 10 - 40 minutes
•
> 300 PPM: Alarm signal within 3 minutes
