13. Recognizing Nuisance Alarms
Smoke Nuisance
HUSH
TM
: If you know why the alarm is sounding, and you can verify that it is not a life threatening situation, you can
push the button on the initiating unit (green LED flashing every second) to silence the alarm for 8-10 minutes. If the
smoke is not too dense, that unit, and all interconnected units will silence. After the Hush
TM
period, the smoke alarm will
automatically reset and sound the alarm if particles of combustion are still present. You can use Hush
TM
repeatedly until
the air has been cleared of the condition causing the alarm.
NOTE: Dense smoke will override Hush
TM
and sound a continuous alarm. 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 or 911.
This 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.
14. Battery Backup
This alarm is powered with AC power, but also contains a sealed lithium battery backup system. No battery installation
or replacement is necessary for the life of the alarm.
NOTE: AC power must be connected to obtain the full 10 year battery and unit life. Constant exposure to high
or low humidity or temperatures may reduce battery life.
NOTE: If AC power is lost, Wi-Fi features (including Indoor Air Quality) will not function, but the backup bat-
tery will still provide smoke detection.
WARNING: NO SERVICEABLE PARTS INCLUDED. DO NOT ATTEMPT TO OPEN THE ALARM FOR ANY
REASON! DO NOT TRY TO REPAIR THE ALARM YOURSELF.
LOW BATTERY
This alarm is equipped with a low battery monitor circuit. If the battery capacity is nearing the point where it can no
longer provide adequate power for all alarm functions, the low battery condition will occur. See Troubleshooting Guide.
The unit must be replaced within 7 days of the first occurrence of the “Low Battery Warning” to provide continuous
alarm detection.
CAUTION: THE BATTERY USED IN THIS DEVICE MAY PRESENT A FIRE OR CHEMICAL BURN HAZARD IF
MISTREATED. DO NOT RECHARGE, DISASSEMBLE, HEAT ABOVE 100°C (212°F) OR DISPOSE OF IN FIRE.
