This type of intercom system allows emergency services to be in constant contact with the people in the refuge areas who seek assistance.
The Disability Discrimination Act made it the responsibility of all companies, nationwide, to ensure that access to buildings and services is available to everyone - there must be no discrimination.
The Emergency Voice Communications System (EVCS) is for use as a Fire Telephone system, Disabled Refuge Call system or as a combined system when both Fire Telephones and Disabled Refuge Points are required.
Designed to comply with BS5839 Part 9 2003 the EVCS is a fixed, secure, bi-directional fully-duplex voice communication system, to assist fire fighters within high rise buildings or large sites where radio communication may not be possible. Where both a fire telephone and disabled refuge system are fitted to a building BS 5839 Part 9 specifies these should form a single system.
