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 alarm circuit for up to 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.
The Red LED will flash every 10 seconds indicating a
temporarily desensitized condition. Some units may chirp
approximately every 40 seconds during Hush. 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.
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.
