AC E20 Connection to AlphaCom E20.jpg
  • Up to 4 units may be mounted in one 19” rack if sufficient ventilation is provided. It is recommended to mount a 24 VDC cooling fan module on top of each exchange unit.
  • The two-pair star wired intercom cables are connected to connection boards on the cabinet DIN rail or in a separate distribution field.
  • Each subscriber line card provides 6 freely programmable Remote Control Outputs (RCO’s).
  • Two RJ45 Ethernet terminals on the IP filter board are used for IP LAN and WAN communication.
  • The serial ports with RS232 and RS422/485 interface are used for interface to equipment using these protocols.
  • 6 program distribution sources can be connected to the APC board via an optional program connection board. Up to 32 extra programs may be added using AGA boards, 16 programs per board.
  • The optional program connection board has input for 6 Remote Control Inputs (RCI) which can initiate programmed actions.
  • The exchange is powered from the mains. The power supply APWR runs on 90-270 VAC.

The built-in power supply serves approximately 80 standard stations when all stations are activated (All Call or Alarm Call). If All- or Alarm Call is not to be activated, the exchange may be fully equipped with 102 stations.
