Removable Euro connectors for terminat-
ing data lines from COntrolMatrix field devices. NOTE: There are no active
electronics or supervision for these connections.
5. STATION CONNECTIONS
Removable Euro connectors for terminating
PCU Series paging stations. Each supply circuit is bi-polar (+15VDC, GND,
-15VDC) and requires a 3-conductor cable suitable for the output load.
There are four supervised circuits with two output connections for a total of
8 PCU Series stations.
6. CONTROL PANEL CONNECTIONS
Removable Euro connectors for ter-
minating ControlMatrix remote control panels. Each supply circuit is sin-
gle-ended (+12VDC, GND) and requires a 2-conductor cable suitable for
the output load. There is one supervised circuit distributed to 4 connec-
tions. Maximum load is 10 ControlMatrix remote panels.
7. RS-485 OUT CONNECTION
Removable Euro connector for distributing
data lines from ControlMatrix field devices to MediaMatrix head-end.
Shield pin is at chassis potential.
8. FAULT CONTACT CONNECTOR
Removable Euro connector for termi-
nating an external fault alarm or control circuit. This connector is internal-
ly coupled to a relay and provides a Form “C” connection (SPDT). The
contacts are rated for 600mA, 125 VAC; 2A at 30VDC.
9. REDUNDANT MODE SWITCH
