USING THE TAMPER RESIST LOCKING MECHANISM

This can be installed by the following directions.
1. Remove the break-away locking pin from the unit by rocking pin back
and forth.
2. Put the smoke alarm back on the mounting bracket. (See
section“HOW TO INSTALL YOUR SMOKE ALARM.”)
3. Using long-nose pliers, grab the head of the locking pin and insert
into hole located on the side of the smoke alarm. See Figure 8.
4. The Tamper Resist feature is now installed and complete.
To Remove:
5. Using long-nose pliers, grasp the head of the locking pin and pull the
pin completely out of the smoke alarm.
6. The smoke alarm can now be removed from the mounting bracket
with a counterclockwise twist.
