Emergency Voice Communication

Emergency Voice Communication (EVC) systems establish vital two-way communication between emergency services and individuals needing evacuation assistance within a building, particularly those who are disabled or mobility-impaired. These fixed, full-duplex systems link a central control point with numerous "outstations" located throughout the premises.

EVC systems are governed by British Standards, forming part of the BS5839 series, which dictates requirements for their design, installation, and maintenance. A typical system includes a master station with a handset and indicators for calls and faults, ensuring constant readiness.

Key components include fire telephones, often mandated in taller buildings or large venues to aid communication during emergencies and phased evacuations. Additionally, disabled refuge systems are required in multi-storey non-domestic buildings, providing safe areas with communication points.

Emergency assist calls are also necessary in disabled toilets, with remote indication at a central point if the area is unoccupied. Integrated EVC solutions, such as Crisis EVC systems, combine disabled refuge, fire telephone, and assist calls onto a single network, enhancing efficiency and simplifying management across various building types.
