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 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.

Product Benefits

  • Fully compliant with EN12767:2007
  • Suitable for use with NE, LE and HE Passively safe columns
  • Above ground system designed and built to your specification
  • 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
