9. Nuisance and Hush
This smoke/strobe alarm is designed to minimize nuisance alarms. Cigarette
smoke will not normally cause the unit to alarm, unless the smoke is blown
directly into the alarm. 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 is immediately known (3 long beeps with
the voice message “Fire! Feu!”and a strobe flash every second), you can
use the Hush feature to silence the alarm for approx. 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.
Hush
®
Control:
Hush
®
control is extremely useful in a kitchen area
or other area prone to nuisance alarms. The Hush
®
feature has the
capability of temporarily desensitizing the alarm circuit for approximately
8-10 minutes.
This feature is to be used only when a known alarm condition,
such as smoke from cooking, activates the alarm. The smoke alarm
is desensitized by pushing the Test/Hush button on the initiating
smoke alarm cover. If the smoke is not too dense, the initiating
alarm will silence immediately with the voice message “Hush mode
activated”and the red LED blinks every 2 seconds. This indicates that
the alarm is in a temporarily desensitized condition (pushing the Test/
Hush button on any unit other than the initiating alarm unit will do
nothing.).
The smoke alarm will automatically reset after approximately
8-10 minutes and sound the alarm and issue a voice prompt stating
“Fire! Feu!” and the strobe will flash once per second if particles of
combustion are still present.
The Hush
®
feature can be used repeatedly until the air has been cleared of
the condition causing the alarm. Pushing the Test/Hush button on the alarm
will end the temporarily desensitized period, resulting in the voice message
“Hush Mode Cancelled. Mode Hush annulé.”
If the smoke is not too dense, after 10 minutes the alarm will return to
normal operation.
NOTE: Dense smoke will override the Hush
®
feature and sound a
continuous alarm and the strobe will flash once per second.
!
CAUTION: Before using the alarm Hush
®
feature, identify the
source of the smoke and be certain safe conditions exist.
