LED Indicators
This smoke alarm is equipped with red and green LED
indicators. The red LED is located under the test button and
has several modes of operation. The green LED is located
under the Hush
®
button and indicates the presence of AC
power.
Standby Condition The red LED will flash every 45
seconds to indicate that the smoke
alarm is operating properly. The green
LED will be lit, indicating the presence
of AC power.
Alarm Condition When the alarm senses particles of
combustion and goes into alarm, the
red LED will flash rapidly (once every
second). The rapid flashing LED and
temporal alarm will continue until
the air is cleared.
Hush Condition The red LED will flash every 10 seconds
as long as the alarm is in Hush
®
mode.
Low Battery Condition The red LED flash will be accompanied
by an audible chirp. Replace the
battery when this condition occurs.
Smoke Sensing Chamber Operation
The alarm will “chirp” if any of the components in the smoke
sensing chamber fail. This chirp will occur between the
flashes of the red LED indicator light. If the “chirp” occurs at
the same time as the red LED flash, see Battery Replacement
section for more information.
