resetting the alarm.

Tamper Resist Feature
To make your smoke/CO 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 5A). 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 5B).
