housing with the circular snaps at the bottom 

of the mounting plate, and push the housing 

directly onto the mounting plate. The two snaps 

at the bottom, as well as the two hidden snaps 

at the top, should make an audible snap when 

fully engaged. Note: Do NOT attempt to mount 

the light unit to its mounting plate at an angle. 

Ensure that the unit is mounted squarely to the 

wall, without leaning, rocking or any gaps.

Attach the unit to the mounting plate:

Apply continuous power to the unit. The test 

switch/indicator light should illuminate red.

Caution: Battery must be connected to

period of time (24 hours or longer) without 

continuous AC power being provided.

full charge.

After full battery recharge, press the test
