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 (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.
