8 Line Master EVC control unit (no handset) c/w line cards and display ; Wall-mounting, needs 2 x 12V 7.0A/H batteries (typically used on networked systems that do not require multiple control points)

The 8 Line Master EVC control unit (no handset) c/w line cards and display ; Wall-mounting, needs 2 x 12V 7.0A/H batteries (typically used on networked systems that do not require multiple control points) is part of the Fire Telephone & Disabled Refuge Systems range from Context Plus, supplied and supported by SPS. The ECU-8NT is an 8 line Master controller (with No handset) designed for use in the fire telephone systems and the disabled refuge systems of Context Plus. It offers communication over 8 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. The ECU-8NT Master controller does not include a handset, thus it is used in networked systems that do not require every master controller to have an operator handset.
