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 8 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 2 seconds for approximately 8 minutes.
This indicates that the alarm is in a temporarily
desensitized condition. The smoke alarm will automatically
reset after approximately 8 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
NOTE: Dense smoke will override the Hush
sound a continuous alarm.
CAUTION: Before using the alarm Hush
