2111. Recognizing Nuisance AlarmsSmoke NuisanceHUSH®: If you know why the alarm is sounding, and you can verify that it is not a life threatening situation, youcan 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 automaticallyreset and sound the alarm if particles of combustion are still present. You can use Hush® repeatedly until the airhas 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 tosee 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 itis located too close to a cooking appliance. Large quantities of combustible particles are generated from spillsor when broiling. Using the fan on a range hood which vents to the outside (non-recirculating type) will alsohelp prevent nuisance alarms from occurring by removing these combustible products from the kitchen.Carbon Monoxide (CO) NuisanceRESET: Pushing the button during CO alarm allows the unit to reset calculations and double check for thepresence of CO. If the unit re-alarms within 6 minutes, it is sensing high levels of CO which can quickly becomea dangerous situation. Move to fresh air and call 911.waRNiNG: iT iS iMpOSSiBLE TO dETERMiNE THE SOURCE OF a CO aLaRM USiNG SiGHT ORSMELL. aLwayS CONSidER a CO aLaRM EVENT aS daNGEROUS.
