Using the Silence Feature
WARNING!
NEVER disconnect the power to your CO
alarm to silence the horn—use the silence
feature. Disconnecting 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 “Alarm” level, it 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.
To silence an interconnected series of alarms,
you must press the Test/Silence button on the
initiating alarm (the unit with the flashing red
light). If you press the Test/Silence on any
other alarm, it will only silence that unit, not
the whole interconnected series.
N
OTE:
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 detector is silenced:
Finding the Source of CO
After an Alarm
Because CO may dissipate by the time an
investigator arrives, it may be difficult to locate
the source of CO. See Chapter 5 “What You Must
Know About CO.”
BRK Brands, Inc. shall not
be obligated to pay for any carbon monoxide
investigation or service call.
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 (LED) continues flashing...
This means...
CO levels are still potentially
dangerous.
If the CO alarm...remains silent....
This means...unit has returned to normal
operation.
