Wiring to zones
Run a Cat-5e cable from the MCU300 to each wall control unit.
Fit a single-gang back box for each WCU300.
Run two standard speaker cables from the WCU300 to mounted
loudspeakers. If video is required, run 75 Ohm video cable (CT100/RG6
high-quality co-axial cable) from the VSU300 main zone connection either
directly to the video display, or to a wall-mounted panel fitted with a
suitable phono/RCA connector.
Cabling tips
Cat-5e cable should be run through the installation in electrical conduit,
either metal, non-metallic, rigid or intermediate, wherever possible. Should
conduit not be available or impractical, cabling running through frames or
beams must be a minimum of 25mm/1inch from the nearest edge of that
structure. If the frame or beam is metallic, then the cable should be
protected by a bush or grommet.
When routing cables around the installation, care must be taken to prevent
kinking and trapping. Any cable ties used must not be tightened any more
than is necessary to hold the cable in place.
Always re-check the colour code of the Cat-5e cable connections to ensure
they are correct.

Pre-installation notes
Please read these notes before commencing installation.
MCU300 A-BUS Wall Control Unit
A-BUS is a standard that allows some compatibility between different
manufacturers A-BUS multi-room products. The MCU300 can be switched
between Opus A-BUS or Standard A-BUS mode. The Opus A-BUS
position is for use with our own Opus WCU300 keypad and gives extra
functions. When used with other manufacturers A-BUS keypads it should
be set to Standard A-BUS or they will not work. The switch is located on
the rear of the MCU300 (see below).
Fix to a hard surface such as a cupboard surface, not to carpet or a soft-
lined surface, as this will inhibit airflow through the unit. Do not situate in
close proximity to any installation which will produce excessive electrical
noise such as dimmer racks etc (these may interfere with the unit). Situate
within three metres of a power socket.
VSU300 Video Switching Unit (where specified)
Locate in close proximity to the MCU300 (maximum of five metres away).
Fix to a hard surface such as a cupboard surface, not to carpet or a soft-
lined surface, as this will inhibit airflow through the unit.
Do not situate in close proximity to any installation which will produce
excessive electrical noise such as dimmer racks etc; these may interfere
with the unit.
