11. Nuisance Alarm And HUSH
This alarm is designed to minimise 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.
HUSH
If you know why the alarm is sounding, and have verified that it is not a life threatening situation, you
can push the “TEST AND HUSH” button initiating unit. This will silence the smoke alarm, and make the
Red LED flash once every 10 seconds, for up to 9 minutes. If the smoke is not too dense, that unit and
all interconnected units will silence. After the Hush period, the smoke alarm will automatically reset
and sound the alarm if particles of combustion are still present. You can use Hush repeatedly until the
air has been cleared of the condition causing the alarm.
Note: Dense smoke will override this Hush mode and sound a continuous alarm. If no fire is present,
check to see if one of the reasons listed in Section 4. LOCATIONS TO AVOID may have caused the
alarm. If a fire is discovered, evacuate and call the fire department.
• Pushing the button on the initiating smoke alarm will silence that alarm and all compatible
interconnected units.
• Pushing the button on any non-initiating hardwired alarm will not silence an alarm in an
interconnected system.
Smoke Alarm Memory
This smoke alarm has a memory function that can identify if the smoke alarm was the initiating unit
since the TEST button was last pressed. Pressing the TEST button will cause the smoke alarm to chirp
rapidly and the red LED to flash rapidly. The alarm memory is reset when the TEST button is released.
This feature can be used after an alarm event, if the initiating smoke alarm had not been silenced by
the Hush Button.
Low Battery Hush
The smoke alarm has a low battery hush feature. When the smoke alarm chirps to indicate a low
battery condition, pressing the Hush button on that smoke alarm will silence the low battery chirp for
8 hours. This user friendly feature allows the smoke alarm to delay the low battery chirp for 8 hours
until it can be attended to at a more convenient time. The smoke alarm will still operate as normal if it
detects the presence of a fire.
