Alarm Nuisance and Hush
This detector is designed to minimize nuisance alarms. Cigarette smoke will not
normally cause the unit to alarm, unless the smoke is blown directly into the detector.
Combustion particles from cooking may set off the alarm if it is located too close to a
cooking appliance. Large quantities of combustible particles are generated from spills
or when broiling. Using the fan on a range hood which vents to the outside (non-
recirculating type) will also help prevent nuisance alarms from occurring by removing
these combustible products from the kitchen.
If the source of a smoke alarm (3 long beeps) is immediately known, you can use the
Hush feature to silence the alarm for approximately 8 - 10 minutes. If no fire is present,
check to see if one of the reasons listed in "Locations to avoid" may have caused the
alarm. If a fire is discovered, get out and call the fire department.
SMART HUSH
TM
CONTROL AND LOCATE FEATURE
HUSH
The SMART HUSH
TM
control is extremely useful in a kitchen area or other area prone
to nuisance alarms. The SMART HUSH
TM
feature has the capability of temporarily
desensitizing the detectors(s) for approximately 8 - 10 minutes. This feature is to be
used only when a known alarm condition, such as smoke from cooking, activates an
alarm. Pushing the Test/Hush button on any initiating detector (GREEN LED flashing
every second), will silence that unit if smoke is not too dense. (In an interconnected
system, all compatible units will also silence.) The smoke alarm will automatically reset
after approximately 8-10 minutes and sound the alarm if particles of combustion are still
present.
