 • After selecting the proper location 
for your alarm, and wiring the AC 
QUICK CONNECTOR harness as 
described previously, attach the 
mounting bracket to the electrical 
box. To ensure aesthetic alignment 
of the alarm with the hallway, or 
wall, the “A” line on the mounting 
bracket should be parallel with the 
hallway when ceiling mounted, or 
horizontal when wall mounted.(See 
Figure 9-F)
 • Pull the AC QUICK CONNECTOR 
through the center hole in the  
mounting bracket and secure the 
bracket, making sure that the  
mounting screws are positioned 
in the small ends of the keyholes 
before tightening the screws. 
 • Plug the AC QUICK CONNECTOR 
into the back of the unit, making 
sure that the connector snaps into 
place. Then push the excess wire 
back into the electrical box through 
the hole in the center of the  
mounting bracket.
 • Install the alarm fully on the  
mounting bracket by rotating the 
alarm in a clockwise direction. (see Figure 9-C for orientation)
NOTE: The alarm will mount to the bracket in 4 positions (every 90 degrees). 
NOTE: Installing the alarm on the mounting bracket will automatically activate the battery backup.
