Back Panel Wiring and Connections (continued)
Wiring - D-DIWAC and DIWAC Wall Controls
1. The PREZONE2 is compatible with the D-DIWAC and DIWAC
wall controls. Connect wall controls from the appropriate zones via
connectors on the back panel as shown in Figure 8.
2. The maximum cable length per wall control is 1640 ft. (500m) using
CAT6 cable (half the conductors used at each pin of the connector)
or 16 AWG, 2 Conductor (16/2) loudspeaker cable.
3. Volume and audio source selection may be controlled
independently for Zones 1 and 2 via the wall controllers. Only one
wall control panel may be connected per
zone.
NOTE:
Data and power are carried across both wire
connections, therefore there is no specific polarity on the
2-pin Euroblock connectors.
Wiring - Ethernet
1. See Figure 8. Connect the PREZONE2
to a network via a router or directly to an
individual device with CAT5e or better
cable.
2. Once connected, users have several
options to access a fully-responsive
webapp to operate the PREZONE2.
See "Network Connections" for more
information on network configuration and
accessing the webapp control page.
Wiring - Priority Out
1. See Figure 9. Connect the 3-pin Euroblock to the override relay in
any line-in volume controls wired in the loudspeaker line for Zones 1
and/or 2, as required.
2. These signals will become active when
either the emergency system or paging is
active to the zone controlled.
3. A priority signal overrides the external
volume control so emergency/paging
messages are heard, regardless of the
physical state of the volume control.
NOTE:
Do not use the priority output continually at full
power.
Wiring - RS232
1. See Figure 9. Connect an external
device to the PREZONE2 via the
RS232 connection. RS232 serves
as a text command interface with the
following port parameters:
• baud rate: 115200
• 8 data bits
• 1 stop bit
• no parity
2. See "RS232 Control" for more information on using text command
protocol with the PREZONE2.
