SIS Mini

Electrical Disconnection Systems

SIS Mini is an electrical disconnection system designed specifically for single isolation of individual illuminated posts or columns. 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.

The Solo monitor board is pre-fitted inside a small IP67 enclosure and installed within a non-passively safe structure or mini pillar supplying power to the passive post or column. The system is fully compliant with EN12767:2007 (Electrical Isolation of Passively Safe Structures) and can be used with any type of passively safe column.
