function, the function is overridden and the
detector sounds.
ATTENTION:
If the CO-concentration is at
200 ppm, the mute function cannot be activated.
Warning when the battery is empty:
If the capacity of the battery decreases, the detec-
tor will beep once. The yellow FAULT LED will blink
every 30 seconds.
Error warning:
If the detector discovers an error, it will beep
twice. The yellow FAULT LED will blink every 30 sec.
Warning at the end of the detector’s service life:
If the CO detector reaches the end of its service
life, the green and red LEDs will blink and
the detector will beep every 30 sec.
If this happens, the detector has to be replaced.
4.5 What to do in case of alarm
NEVER IGNORE THE CO-ALARM
CO is called the »silent killer« because it is an
invisible, odourless and tasteless gas. It arises
from the incomplete combustion of fossil fuels.
