Operation

Hush
®
Control Feature
Smoke alarms are designed to minimize nuisance alarms.
Cigarette smoke will not normally set off the alarm, unless the
smoke is blown directly into the alarm. Combustion particles
from cooking may set off the alarm if the alarm is located close
to the cooking area. Large quantities of combustible particles are
generated from spills or when broiling. Using the fan on a range
hood that vents to the outside (non-recirculating type) will also
help remove these combustible particles from the kitchen. The
Hush
®
button is extremely useful in a kitchen area or other areas
prone to nuisance alarms.
The Hush
®
feature has the capability of temporarily desensitizing
the smoke alarm circuit for about 7 minutes. This feature is to be
used only when a known alarm condition, such as smoke from
cooking, activates the alarm.
If the alarm does sound, check for fires first. If a fire is
discovered, get out and call the fire department. If no fire is
present, check to see if one of the reasons listed in
Locations to
Avoid
may have caused the alarm.
The smoke alarm is desensitized by pushing the Hush
®
button on
the smoke alarm cover. If the smoke is not too dense, the alarm
will silence immediately
and the red LED will flash every 10
seconds for 8 minutes.
This indicates that the alarm is in a
temporarily desensitized condition. The smoke alarm will
automatically reset after approximately 7 minutes. If after this
period particles of combustion are still present, the alarm will
sound again.
The Hush
®
feature can be used repeatedly until the air has been
cleared of the condition causing the alarm. Pushing the Test
button on the alarm will 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.
