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.
