erratic or low volume sound, the unit must be replaced. See Permanently Disable Alarm / Discharge Battery section to

determine how to prepare the unit for shipment or disposal.

NOTE: If you push the test button on your alarm, the app will send you a text message. However, if you conduct a

remote test using the app, you will not receive a text message.

WARNING: DUE TO THE LOUDNESS OF THE ALARM, ALWAYS STAND ABOUT 2.5 FEET AWAY FROM

THE UNIT OR USE EAR PROTECTION WHEN TESTING.

WARNING: DO NOT USE AN OPEN FLAME TO TEST YOUR ALARM, YOU COULD DAMAGE THE ALARM

OR IGNITE COMBUSTIBLE MATERIALS AND START A STRUCTURE FIRE.

Ambient Light Sensing

In low light ambient conditions, the green LED ring fades to off, and then blinks approx every 60 seconds.

This unit samples the ambient light conditions of the alarm’s location and, if possible, determines a Night / Day cycle. A

valid Night / Day cycle will delay unit chirps during the night until the next Day cycle begins.

Chirping

When chirping begins during the next Day cycle, you can temporarily silence End of Unit Life or Network Error chirps by

pressing the button. Low Battery chirps cannot be silenced.

If a valid Night / Day cycle has not been established because the unit is located in either a constantly dark or lighted

location, the chirps mentioned above will not be delayed at night. Moving the unit to a different location might allow the

unit to determine a valid Night / Day cycle.

WARNING: REPLACE UNIT AS SOON AS POSSIBLE WHEN IN END OF UNIT LIFE OR LOW BATTERY MODE.

13. Recognizing Nuisance Alarms

Smoke Nuisance

SMART 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 Smart Hush® period, the smoke

alarm will automatically reset and sound the alarm if particles of combustion are still present. You can use

Smart Hush® repeatedly until the air has been cleared of the condition causing the alarm.

NOTE: Dense smoke will override Smart 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
