PCMZPM
BGM Options
A three-column jumper field is available to connect or disconnect each zone
output to the background music bus. Place the jumper in the OUT position to
disconnect the zone from the BGM bus. Place the jumper in the IN position to
connect the zone to the BGM bus.
NOTE: Each zone requires 2 jumpers to be moved to the same position as indicated
by the brackets for each zone label.
Local BGM
The PCMZPM module can accept input from a secondary (local) BGM source.
Move the GLOBL BGM jumpers to the out position, and connect the BGM
source to the terminal strip labeled LOCAL BGM IN & RT. (See the illustrations
in the Applications section of the PCMCPU manual for examples of this type of
configuration wiring.)
NOTE: The local BGM source must be compatible with the types of speakers installed
on the zone outputs, that is, low level when used with separate zone amplifier or ampli-
fied speakers and high-power 25V or 70V when used with passive speakers.
Zone Wiring
The speaker of each paging zone connects to the appropriate screw terminals
on the connector block. These are labeled ZONE A, ZONE B, and ZONE C.
Each connection is marked + and - as a means of identifying phasing of the zone.
Typically, speaker returns go to - and speaker feeds go to +.
2-conductor shielded wire is recommended for speaker installation. One side of
the shield is grounded through the amplifier and the other side is left floating
with no connection. See illustration on page 6.
NOTE: A white block next to the zone output terminals is provided to write the actu-
al system zone number for that set of terminals. Use an indelible marker to write in
the zone numbers.
