Install the Station into the Backbox
Spacers are provided in the termination kit to help align the station and cover flush against the wall in
flush mount applications.The spacers are not needed on surface mount backboxes.
Step 1:
Insert the station electronics and wiring into the backbox. The arrow on the mounting plate
must point up.
Step 2:
If needed, fold the spacer in a zigzag fashion and press together to achieve the required
thickness to fill the gap between the station and backbox. Cut off and discard the excess
material and place the spacer between the station and backbox.
Step 3:
Secure the station to the backbox with the two screws provided. If using spacers, the
screws install through them.
Install the Faceplate
The faceplate is secured to the station with two magnets that are located on the bottom side of the
faceplate.
Step 1:
Align the top of the faceplate approximately 20 degrees from the station.
Step 2:
Hook the top of the faceplate to the tabs located on the station electronics assembly. To
ensure the faceplate is hooked properly on the top hook, wiggle it slightly side to side
while the bottom is angled 20 degrees from the wall.
Step 3:
Swing the bottom of the faceplate down until the magnets engage.
Step 4:
If the faceplate does not fully attach automatically, wiggle the bottom of the faceplate until
the magnets are seated properly to the station and the faceplate is secure.
N o t e :
For some flush mount applications with certain trim rings it may be necessary to
remove the station’s back cover before installation into the backbox.
N o t e :
To improve successful station and wall plate installation, do not overtighten the
screws.
