Switches are equipped with RS485 ports which can be used for the interconnection of intruder systems. A special way of processing data received via RS485, their protection via VLAN, and high QoS assignment ensure compatibility with EN-50131-1 standard for intruder systems. We verify this every 3 years in the testing laboratory.
As a safety precaution, all LAN-RING switches support advanced VLAN management guaranteeing separate VLANs for:
- RS485 transmission (alarm panels, PIDS, ACS, automation),
- IO transmission,
- Cameras, servers etc.
Data in VLANs can be assigned with different priorities in accordance with QoS standards. Thanks to these measures, the data from RS485 ports aren´t available on FE/GE ports and are transmitted with the highest priority. Switches have been tested together with alarm systems DOMINUS, GALAXY and SPC as a transmission system for alarm panels with security grade 3 or 4.
