Smoke HUSH Control Feature
The HUSH feature has the capability of temporarily desensitizing
the smoke alarm circuit for approximately 9 minutes. This feature
is to be used only when a known alarm condition, such as smoke
from cooking, activates the alarm. When the unit is in 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 9 minutes. This indicates that the
smoke alarm is in a temporarily desensitized condition. Your
Smoke/CO Alarm will automatically reset after approximately 9
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 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.
