The CO alarm carries out a continuous self-test. Flashing of the yellow FAULT indicator
indicates the presence of a fault. In addition, two short signal tones are issued per
minute.

If the FAULT indicator is active, there is a defect in the device or the CO alarm is worn
out after a service life of approx. 6 years.
The CO alarm must be replaced in this case!
Digital display
The carbon monoxide alarm is equipped with a digital display (LCD display) to show
the CO concentration. The unit shown on the display is parts per million (ppm). The
LCD display can show values between 30 and 999 ppm.
Normal mode
No values are shown if the ambient air is normal.

What to do in the event of an alarm
Remain calm in the event of an alarm. Carry out the following measures:
Open all doors and windows to increase ventilation and allow the carbon monoxide
to escape.
Stop using all combustion devices and, if possible, make sure they are
switched off.
If the alarm continues, clear the building. Leave doors and windows open.
Do not enter the building again until the alarm signal has muted.
Get medical assistance for anyone who shows symptoms of carbon monoxide
poisoning. Draw attention to the fact that carbon monoxide poisoning is suspected.
