Installation Guide

NOTE: AC power should be turned off at this stage.

• 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.

• Pull the AC QUICK CONNECTOR through the cen-

ter 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 locks on the

connector snap 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.

NOTE: The alarm will mount to the bracket in 4

positions (every 90 degrees).

• Turn on the AC power. The green AC Power On Indicator should be lit when the alarm is operating from AC

power.

NOTE: Attaching AC power first, without pulling the battery pull tab, will result in a false low battery

trouble condition (see Troubleshooting Guide). You need to activate the battery to eliminate the false low

battery notifications. Pull the battery pull tab before, or very soon after applying AC power to avoid false

low battery notification.
