PASSIVE SAFETY SOLUTIONS:
SIS Quad (Traffic Signals)
In this crash test a standard steel Ø114mm traffic signal post is installed in a RS115 socket and fitted with a SIS electrical disconnection system. An impact sensor is attached to the post and connected to a monitor board in the electrical cabinet. On impact the SIS activates isolation in 0.125 seconds and is fully compliant with electrical wiring regulations and EN12767. The SIS system can also be used to manually disconnect the power to a post for maintenance.
