11. 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 to silence the alarm for 8-10 minutes. If the smoke is not too dense, that
unit 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.
Carbon Monoxide (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.
WARNING : Although RESET can be used for CO alarm events, it is impossible to
determine the source of a CO alarm using sight or smell. Always consider a CO alarm event as dangerous.
