Product Details

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

BS5839-9:2011 covers the design, installation and operation of fire telephones and disabled refuge systems in buildings, and where both systems are fitted to a building, the standard specifies these should form a single system.

The EVX-OSB is a type B EVCS outstation compatible with the EVX standalone and network systems.

The outstation is supplied with a brushed stainless finish and a green flashing button to aid location. The ability to use a standard ‘MK’ double gang back box means only one type of panel is required for flush and surface installations reducing stocking requirements.
