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.

The EVX-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 BS 5839-9:2021.

The EVX-EX8 has inbuilt networking allowing it to form one of the 64 panels on a EVX network installation allowing a total of 512 outstations to be accommodated. Each panel on the EVX network can be a master station or EVX-EX8 system expander.

The display on the front of the EVX-EX8 gives the current call or fault status of each line of the local panel aiding fault finding.
