Use and Care Manual
D. Tamper Resist Feature:
To make your smoke alarm tamper resistant, a tamper
resist feature has been provided. Activate the tamper resist
feature by breaking off the four posts in the square holes
in the trim ring (see figure A). When the posts are broken
off, the tamper resist tab on the base is allowed to engage
the mounting bracket. Rotate the alarm onto the mounting
bracket until you hear the tamper resist tab snap into place,
locking the alarm on the mounting bracket. Using the
tamper resist feature will help deter children and others
from removing the alarm from bracket. NOTE: To remove the
alarm when the tamper resist tab is engaged, press down on
the tamper resist tab, and rotate the alarm off of the bracket
(see figure B).
