The BMS / Graphics Interface allows BMS systems or Graphical PCs to be integrated with the 4000 series of fire control panels and remote terminals. 4120 or 4121 units collects data of Fire & Fault from all the panels on Network & feeds it to BMS Systems or Graphics software. The interface is an integral part of the Velox Apex network permitting the handling of all network traffic and event prioritisation, via a PC, using a simple RS232 connection. Multiple interfaces can be connected to the network catering for sites requiring control from a number of Graphical PC’s or BMS Systems. Graphical PCs with Windows OS needs a Velox Graphical Software & RS-232 Com port for communication with 4120 / 4121 units. BMS Systems needs a 4130 Velox BACNET/MODBUS IP Integrator for communication with 4120 / 4121 units. Single unit of 4120 or 4121 can collect data from 200 panels using the same Velox Apex network making it true ‘Power of One’ device.
