CABLING
WALL PLATES
The wall plates are wired in a home run (star) configuration. One is installed in each room and is wired to
the BMS. The wall plates mount in a standard 2 gang electrical box.
Use standard Cat-5 cable (four twisted pair 24 AWG solid, shielded). Use Belden 1584A or equivalent.
The home run distance to any wall plate should not exceed 1000 feet. If 8 ohm speakers are going to be
directly driven from the line out on the wall plate then the maximum cable distance should not exceed 500
feet.
Refer to the figure for the chassis terminal identification.
The Cat-5 connectors should be terminated to correspond with this figure.
Pair 1 White/Blue (4) (Green) Blue/White (5) (Red)
Pair 2 White/Orange (1) (Black) Orange/White (2) (Yellow)
Pair 3 White/Green (3) (White) Green/White (6) (Blue)
Pair 4 White/Brown (7) (Orange) Brown/White (8) (Brown)
All these Cat-5 cables are wired straight thru (pin 1 to pin 1 etc.).
The audio connections from these wall plates are detailed on the next page.
MAIN UNIT
There are two sets of audio inputs to the main unit, program audio (music sources) and line level mixer
inputs that carry the paging audio source.
The program audio inputs are three terminal pluggable screw connectors. They accept stereo audio and are
wired with H the high side and GND the shield of the cable for both left and right input connections.
These are unbalanced inputs.
The mixer inputs (page audio) are balanced inputs and are wired with the Red wire to H, the Black wire to
L, and the Shield to SH.
POWER SUPPLY (S)
Either one or two power supplies will be supplied with the system. Only one supply is required if the sys-
tem will only use either the headphone outputs and/or the line level outputs. If the installation calls for a
direct speaker hookup then the additional supply will be required if the rooms serviced exceed 16.
