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 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 type of passively safe structure.

Guaranteed electrical isolation of all volts within 0.2 seconds of impact Guaranteed isolation even if the structure has not detached from its base Provides isolation of individual structures or circuits Provides fault outputs for impact, voltage drop and maintenance issues Fault outputs can be connected to CMS or RMS systems Simple to test at commissioning stage and for periodic maintenance Successfully tested at MIRA
