• Turn on the AC power. The green AC Power On Indicator should be lit when the alarm is operating from AC power.
NOTE: Attaching AC power first, without rotating the alarm onto the mounting bracket, will result
in a false low battery trouble condition chirp (see Troubleshooting Guide). You need to activate
the battery to eliminate the false low battery trouble condition chirps. Attach unit to mounting
bracket very soon after applying AC power to avoid false low battery notification.
NOTE: The battery activation is a one-time feature that occurs when the red wheel is turned to the
"ON" position with a screwdriver, or when the alarm is rotated fully onto the mounting bracket. After
activation, the battery cannot be turned off, and can only be permanently discharged in the event of a
fatal fault or at the end of unit life. If the alarm is removed from the mounting plate, the backup battery
will remain active. See Permanently Disable Alarm / Discharge Battery section.
