SigTEL Disable Refuge System 4 or 8 Line Master Controller

SigTEL 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.

Key Features
