Chirping

When chirping begins during the next Day cycle, you can temporarily

silence End of Unit Life chirps by pressing the Test/Hush® 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.

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.
