The ECS system is comprised of master stations, sub-stations, remote stations, and optional telephone interface. The system utilizes a Central Exchange to link the various stations into one network. For special applications, systems are available without a Central Exchange.


The Central Exchange operates and controls the entire network. It contains the amplifiers, microprocessors, data communications line drivers, line switching boards and cable termination boards. Modular cabinets are available in multiples starting at 8 stations and expandable to accommodate more than 256 stations.

The entire ECS intercom system operates from 24-48VDC supplied from a 120/220-240VAC, 50-60Hz power source. Emergency battery powered systems, with ratings of four hour operation, can be provided as optional equipment.
