The 16 Line Master EVC control unit c/w line cards, handset and display. Wall-mounting, needs 2 x 12V 7.0A/H batteries is part of the Fire Telephone & Disabled Refuge Systems range from Context Plus, supplied and supported by SPS. The ECU-16 is a 16 line Master controller designed for use in the fire telephone systems and disabled refuge systems of Context Plus. The ECU-16 Master controller allows an operator to communicate with up to sixteen fire telephone or disabled refuge outstations. It offers dual communication over 16 lines. It is a simple, effective two-way communication over 16 lines. It can be networked with other 16 line, 8 line and 4 line Master controllers to create a fire telephone system or a disabled refuge system with up to 224 dual communication lines.
