D. Tamper Resist Feature:
To make your smoke alarm tamper resistant, a tamper resist
feature has been provided. Activate the tamper resist fea-
ture 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).
