SIS Pillar
Electrical Disconnection Systems
SIS Pillar is an electrical isolation system specifically for lighting columns and illuminated sign applications. Each pole is fitted with a small sensor that, in the event of an impact, communicates with the monitor board triggering complete LV and ELV isolation within 0.2 seconds. Monitor boards are din rail mounted within a standard street lighting cabinet, providing electrical isolation to individual columns or circuits.
The system is fully compliant with EN12767:2007 (Electrical Isolation of Passively Safe Structures) and can be used with any passively safe structure.
