11. 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 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 discov-
ered, 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.

• Pushing the button on the initiating CO or Smoke/CO combination alarm will silence that alarm and all
compatible interconnected units.
• Pushing the button on any hard-wire smoke alarm will do nothing to silence an interconnected CO alarm.
