connectors of the two DCM1s. The paging commands for
Zones 1 to 8 should be wired to the PAGING ACCESS
connector of DCM1 #1, and those for Zones 9 to 16 to that
of DCM1 #2. The general wiring procedures described at
page 26 should be followed.
Music Mute Input
The MUSIC MUTE inputs on the two DCM1s can be
paralleled together, though this is not ideal. A preferred
solution, if available, is to use a separate set of emergency
system contacts for each DCM1 making up the system.
RS-232 Control
If the DCM1s are to be controlled via RS-232 by an
external control system, the two DCM1s should be treated
independently. Connect each DCM1’s
RS232 INTERFACE
to a separate RS2-32 port on the system controller. The
controller should be programmed to address each unit
independently.
Ethernet interface
Two DCM1e’s should each have their ETHERNET
INTERFACE
port connected to two separate ports on
the network switch. Ensure that the units have different IP
addresses. Each unit can then be controlled via the browser
interface independently.
