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 detector (green LED flashing every second, interrupted by T3 RED LED
alarm pattern) to silence the alarm for 8-10 minutes. If the smoke is not too dense, that detector, and all
®
interconnected detectors will silence. After the HUSH period, the smoke detector 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 of the building and call the fire department.
This detector is designed to minimize nuisance alarms. Cigarette smoke will not normally cause the
detector to alarm, unless the smoke is blown directly into the detector. 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.

In an interconnected system (all detectors will be alarming together), a detector that detects smoke or
CO and initiates an alarm is called the "initiating alarm detector." Initiating alarm detectors will be flashing
the Green LED every second during alarm (interrupted by the T3 RED LED alarm pattern). Depending
on detector locations, and the location of the source of smoke or CO, it is possible to have more than one
initiating detector. If you suspect a nuisance alarm situation, you can use this feature to help you locate the
initiating alarm detector(s) in a wireless alarm interconnect system. Push the button on any non-initiating
wireless detector, and ALL wireless detectors EXCEPT the initiating alarm detector(s) will silence for two
minutes. You can use the LOCATE feature repeatedly until you find the initiating alarm detector(s), or the air
has been cleared of the condition causing the alarm.
®
NOTE: HUSH and Locate features are dependent on the type of models enrolled in the wireless inter-
connect system. Non-wireless models cannot be enrolled in the wireless interconnect system and therefore
cannot receive the wireless Locate feature; they will continue to alarm until the initiating detector is Hushed
or the Smoke/CO condition clears.

can be used for CO alarm events also, but it is impossible to determine the source of a CO alarm
using sight or smell. Always consider a CO alarm event as dangerous.
