Using The Silence Feature - First Alert MODEL FCD3N User Manual

Using the Silence Feature

WARNING!
NEVER remove the batteries from your
CO Alarm to silence the horn. Use the
silence feature. Removing the batteries
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 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 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 alarm is silenced:
If the CO Alarm...
remains silent after you pressed the Test/
Silence button...
This means...
CO levels are dropping.
If the CO Alarm...
goes back into alarm 4 minutes after you
pressed the Test/Silence button...
This means...
CO levels present indicate a potentially
dangerous situation.
