different batteries may have a detrimental effect on the

the battery at least once a year, or at the same time you
change your clocks for daylight saving time.
Remove the alarm from the mounting bracket by rotat-
ing the alarm in the direction of the “OFF” arrow on the
cover. To disconnect the AC power harness, squeeze
the locking arms on the sides of the Quick Connector
