LED Indicators
This alarm is equipped with a red LED indicator, with three
modes of operation.
Red LED - Flashing every 40–45 seconds:

smoke alarm is operating properly.
Red LED - Flashing:
When the Test button is pressed, or

flash once per second. The flashing LED and pulsating alarm
will continue until the air is cleared.

Alarm Removal
To remove the alarm from the mounting plate, rotate the
alarm in the direction of the “OFF” arrow on the cover. If
the tamper-resist feature has been used, refer to
Alarm
Tamper-Resist Feature
section for removal instructions.
This smoke alarm uses a 9 V battery (carbon zinc, alkaline
and lithium batteries may be used). A fresh battery should
last for one year under normal operating conditions.
This alarm has a low battery monitor circuit which will cause
the alarm to “chirp” approximately every 30-40 seconds for a
minimum of seven (7) days when the battery gets low.
Replace the battery when this condition occurs. The low
battery chirp will occur at the same time as the red LED flash.
