Alarm silence:
It is possible to temporarily silence
the alarm up to two times if the level
of CO that triggered the alarm is
less than 200ppm. After ventilating
the property you can temporarily silence the
alarm by pressing the Test/Mode button, the
alarm will stop and the silence mode symbol
will appear on the screen. The silence mode
willlastforupto3minutes.IftheCOlevel
remains too high the alarm will trigger again
or if the level of CO rises above 200ppm
then the detector will automatically re-enter
alarm mode. If the level of CO has fallen
to a satisfactory level the silence mode icon
will disappear, the unit will exit alarm mode
and the segments of the bar graph will slowly
disappear as the CO in the sensor clears.
Alarm in absence:
IfthePeaklevelreadingsymbolis

are found to be incorrect, the detector will
emit a single chirp once per minute and the
display will show “Err” for error and an error
code,cycling between “Err”and the particular
error code.
