alarm, attach the mounting bracket to the wall 
or ceiling. 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. (Figure 9-A).
 • Install the alarm fully on the mounting 
bracket by rotating the alarm in a clockwise 
direction. (Figure 9-B)
 NOTE : The alarm will mount to the bracket 
in 4 positions (every 90 degrees).
 • Pull out the battery pull tab to activate the 
battery.(Figure 9-C) 
 • Battery activation is confirmed with a single 
power-on chirp, and a voice prompt to  
“Push Test Button.”
 • If pulling the battery tab does not result in  
the chirp and voice notifications, open and  
close the battery compartment once.  
Confirm power activation.
 • The alarm is now activated! After  
installation / activation, test your alarm as  
described in Operation and Testing section.
