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-228 Master station can accept up to eight lines of outstation, (type A fixed phones, type B refuge hands free points, emergency assist call 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 BS5839-9:2011 Assist Calls can be acknowledged by pressing the zone key (as required by BS8300) and will return to alarm if not reset within two minutes.
The EVX-228 has inbuilt networking allowing it to form one of the 64 panels on a EVX network installation, or allowing a repeater using another EVX-228, where buildings have two points of control.
When networking at least one EVX-TMS touchscreen master station is required to act as the master control and indicator panel.
Starting at two lines the EVX-228 is ideal for small buildings which are required to have an EVCS, but which have a limited number of outstations.
The EVX-228 is a self contained enclosure housing a master handset, one to four dual line cards, an EN54-4:A2 2006 power supply & battery charger and can be surface or flush mounted (Using the EVX-CBZ Bezel)
The case is made from powder coated zintec, with a smoked perspex door covering the handset.
20mm cable knockouts are provided for all necessary cables as well as space for the backup 12V VRSLA battery.
The master station is microprocessor controlled, but requires no programming on site; the panel is fitted with end of line resistors which are simply moved to the end of line when an outstation is connected.
