Read more SigTEL Compact 4-64 Line EVC System Our SigTEL Compact 4-64 line emergency voice communication system is ideal for use in all disabled refuge and fire telephone applications. In disabled refuge applications, it allows people who cannot easily evacuate a building to communicate with a central control point during a fire emergency. In fire telephone applications, it allows building management, the emergency services and fire marshals to communicate with each other before, during and after a fire. It comprises a range of low-cost wall-mounting Controllers which can handle 4 or 8 lines (dependent on the model purchased). Typically located in a building’s control room or a fire services access point, each Controller allows management and/or the emergency services to communicate via telephone-style handsets with the system’s ‘outstations’. For larger systems, an 8 line expansion unit allows systems of up to 12 or 16 lines to be easily implemented. An optional network communication card can be used to interlink up to four Master Controllers for systems of up to 64 lines. The system is fully monitored, extremely cost-effective and meets and exceeds the requirements of BS 5839 part 9 when correctly installed.
