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. The Lexicomm ViLX-EX8 system expander panel can accept up to eight lines of outstation, (Type

A fixed phones, Type B refuge hands free points, emergency assist alarm point or jack points in Far East and Middle East applications) as required. Lines auto identify by flashing Red for EVCS calls, Blue for assist calls or flashing Green for Connected calls as detailed in BS5839-9: 2021.

The ViLX-EX8 has inbuilt networking allowing it to form one of the 64 panels on a Lexicomm network installation allowing a total of 512 outstations to be accommodated. Each panel on the Lexicomm network can be a master station or ViLX-EX8 system expander.The display on the front of the ViLX-EX8 gives the current call or fault status of each line of the local panel aiding fault finding. The Lexicomm ViLX-EX8 is a self contained enclosure housing a display, one to four dual line cards, an EN54-4:A2 2006 power supply & battery charger and is surface mounted, the small form factor makes it ideal for locating in electrical risers.

The system expander panel is configured from any master station on the system using a spreadsheet (excel or open office) and installed via an MMC card. Each outstation has three labels, one for Emergency Assist, one for EVCS and one for Fault text, each label is two lines of twenty characters.
