First Alert MODEL FCD3N Using the Silence Feature, While the alarm is silenced If the CO Alarm

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.
