12. Recognizing Nuisance Alarms
Smoke nuisance
HUSH®:
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® 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 Hush® 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.
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.
Co nuisance
RESET: Pushing the button during CO alarm allows the unit to reset calculations and double check for the presence of
CO. If the unit re-alarms within 6 minutes, it is sensing high levels of CO which can quickly become a dangerous situation.
Move to fresh air and call 911.
