8. Nuisance and Hush
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
9 minutes.
This feature is to be used only when a known alarm condition, such as
smoke from cooking, activates the alarm. Pushing the Test / Hush but-
ton on the smoke alarm cover will issue a voice prompt stating “Hush
Mode Activated. Mode Hush activé.” and desensitize the smoke alarm.
If the smoke is not too dense, the alarm will silence immediately and
the red LED will blink every 10 seconds. This indicates that the alarm is
in a temporarily desensitized condition.
The smoke alarm will automatically reset after approximately
9 minutes and sound the alarm and issue a voice prompt stating “Fire!
Feu!” 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 during
Hush
®
mode on the alarm will issue a voice prompt stating “Hush Mode
Cancelled. Mode Hush annulé.”and end the temporarily desensitized
period.
Voice message, “Hush Mode Cancelled. Mode Hush annulé”, is
announced by one of the following conditions:
1. The user cancels Hush mode by pressing the Test button while
Hush
®
mode is active and the smoke level is below the alarm
threshold.
2. The Hush mode timer expires, (approximately 9 minutes) and the
smoke level is still below the Alarm Threshold.
Note: If the smoke level drops below the Alarm Threshold while in
Hush mode, no voice message occurs.
If the smoke is not too dense, after 9 minutes the alarm will return to
normal operation.
NOTE: Dense smoke will override the Hush
®
feature and sound a
continuous alarm.
!
CAUTION: Before using the alarm Hush
®
feature, identify the
source of the smoke and be certain safe conditions exist.
