Using the Silence Feature

WARNING!
NEVER unplug your CO alarm to silence the
horn. Use the silence feature. Unplugging
the CO alarm removes your protection!
See previous page for details on responding
to an alarm.
The silence feature is intended to temporarily
silence your CO Alarm's alarm horn while you
correct the problem—it will not correct a CO
problem. While the alarm is silenced, it will
continue to monitor the air for CO.
When CO reaches the Full Alarm level, the
Alarm will sound— repeating horn pattern:
4 beeps, a pause, 4 beeps, etc. Press and hold
the Test/Silence button until the horn is silent.
The initial Silence cycle will last approximately
4 minutes.
NOTE:
After the initial 4-minute Silence cycle, the
CO Alarm re-evaluates present CO levels and
responds accordingly. If CO levels remain
potentially dangerous—or start rising higher—
the horn will start sounding again.
While the detector is silenced:
If the CO Alarm... is silent for only
4 minutes, then starts sounding loudly—
4 beeps, then a pause, 4 beeps, then a pause.
Red light continues flashing...
This means... CO levels are still potentially
dangerous.
If the CO Alarm... remains silent .
Only the green light is on....
This means... unit has returned to normal
operation.
