USING THE TAMPER RESIST LOCKING MECHANISM
To make the smoke alarm somewhat tamper resistant, a “locking pin” has been provided
in the base of the unit. It will help deter a child or other individual from removing the
smoke alarm from the bracket. See Figure 7. The following directions can install this.
1. Remove the breakaway 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 counter-
clockwise twist.
