HUSH
®
Control Feature
The HUSH
®
feature has the capability of temporarily desen-
sitizing the smoke alarm circuit for approximately 10 min-
utes. This feature is to be used only when a known alarm
condition, such as smoke from cooking, activates the alarm.
You can put your Smoke/CO Alarm in HUSH
®
mode by
pushing the test/reset button. If the smoke is not too dense,
the alarm will silence immediately, the unit will verbally
announce “HUSH MODE ACTIVATED”, and the green LED
will flash every 2 seconds for approximately 10 minutes.
This indicates that the smoke alarm is in a temporarily
desensitized condition. Your Smoke/CO Alarm will automat-
ically reset after approximately 10 minutes. When the unit
returns to normal operation after being in HUSH
®
mode, it
will verbally announce “HUSH MODE CANCELLED”, and
sound the alarm if smoke is still present. The HUSH
®
fea-
ture can be used repeatedly until the air has been cleared of
the condition causing the alarm. While the unit is in
HUSH
®
mode, pushing the test/reset button on the alarm
will also end the HUSH
®
period.
