Alarm Tamper Resist Feature
This alarm is equipped with an automatic tamper resist
feature that prevents someone from removing the unit
from the mounting plate. The feature engages when the
alarm is rotated onto the mounting plate.
Rotate the alarm onto the mounting plate until you hear
the tamper resist tab snap into place, locking the alarm.
To remove the alarm, press on the tamper resist tab, and
rotate the alarm off of the mounting plate (Image 4).
