WALLPLATES
The wallplates can be wired in either a home run (star) or modified daisy chain configuration.
Use two twisted pair 22 AWG stranded, with an overall shield (West Penn # 3651) if the home run
configuration is employed for each wallplate and total distance to any wallplate does not exceed 1000
feet.
Use two twisted pair 18 AWG stranded, with an overall shield (West Penn #3751) if the wallplates are
daisy chained together (it is recommended to only daisy chain 6 wallplates per home run) with no more
than 1000' total wire length.
Refer to the figure for terminal identification. Four screw terminals are provided on the rear of the
wallplate for cable hook-up.
One is installed in each room and is wired to the ACU. The wallplates mount in a standard 2 or 3 gang
electrical box. An eight position dip switch on the rear of the wallplate is used to assign the wallplate's
room address. This switch is preset at the factory to the area identified on the front of the wallplate
itself, but should be checked prior to installation.
The system is shipped in a default setting for all dip switches which will permit instant operation of the
system in its usual configuration. Please refer to the DIP SWITCH section for details on all the dip
switch functions.
