Vanderbilt’s SPC was recently deployed to act as part of a security and communication solution between a toll booth and plaza located on the M1 between Dublin and Belfast. At night time, the toll system is automated and therefore an intruder alarm system was needed for protection. The distance between the toll booth and plaza is 6.2 kilometres and the security systems – SPC and video cameras – had to be able to connect and operate over that distance so operators could get an overview of activity at each site.
SPC replaced an existing Europlex legacy product that had the IFS fibre drivers connected and working on multimode fibre over the 6.2 kilometre distance. Due to this distance, the fibre driver was bespoke. Multimode is usually only specified for approximately two kilometres. However, when the 3GS legacy system was replaced for a new SPC panel, the communication over the fibre link stopped working.
