Operation
Determining what type of alarm has sounded is easy
with the Kidde Combination Smoke/CO Alarm. The
voice message warning system will inform you of the
type of situation occurring. Refer to the Features
section for a detailed description of each alarm pattern.
HUSH Control Feature
®
The HUSH feature has the capability of temporarily
®
desensitizing the smoke alarm circuit for approximately
10 minutes. 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 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. The unit will automatically reset after
approximately 10 minutes. When the unit returns to
normal operation after being in HUSH ® mode the alarm
will sound if smoke is still present. The HUSH feature
®
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.
®
NOTE: Dense smoke will override the HUSH ® control
feature and sound a continuous alarm.
CAUTION: Before using the alarm HUSH ® feature,
identify the source of the smoke and be certain a safe
condition exists.
