An EVCS is a fixed, secure, bi-directional, full duplex voice communication system to assist firefighters during emergencies in high rise buildings or large sites where radio communication cannot be guaranteed to work due to interference from the fire plasma.

The EVX-228S Solo range of master stations is perfect for smaller installations of up to 8 lines. It requires no set up and is easy to install with a single radial circuit to each outstation.

The full range of EVX outstations are compatible and include Type A outstations, Type B Outstations, Type C outstations and jack points for use in far and middle east applications.

Lines auto identify by flashing Red for EVCS calls, Blue for assist calls or flashing Green for connected calls as detailed in BS 5839-9:2021.

The Assist Call range of emergency assistance alarms is fully compatible. It has become very popular to add these devices as an integrated system. This has several benefits namely:- fault monitored wiring, fully line powered (No mains supply), battery back-up via the master station.

BS 8300 requires that audible and visual feedback should be provided to indicate that, when the alarm has been operated, the emergency assistance call has been acknowledged and actioned. Assist Call meets this requirement and will return to alarm if not reset within two minutes.
