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 Section 8. 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.
LOCATE
In an interconnected system (all units will be alarming together), a unit that detects smoke and initiates an 
alarm is called the “initiating alarm unit.” Initiating alarm units will be flashing the Green LED every second 
during alarm. Depending on unit locations, and the location of the source of smoke, it is possible to have 
more than one initiating unit. 
If you suspect a nuisance alarm situation, you can use this feature to help you locate the initiating alarm 
unit(s) in a wireless alarm interconnect system. Push the button on any non-initiating wireless unit, and 
ALL wireless units EXCEPT the initiating alarm unit(s) will silence for two minutes. You can use the LOCATE 
feature repeatedly until you find the initiating alarm unit(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 in your interconnect system. 
Non-wireless models cannot receive the wireless Locate feature and will continue to alarm until the 
initiating unit is Hushed or the Smoke/ CO condition clears.
