Tigo Rapid Shutdown Signal Detector (SKU Part Number 400-00900-00)
Tigo RSS Signal Detector
Tigo's RSS (Rapid Shutdown) Signal Detector is a functionality testing device for sensing the power-line communication (PLC) signal from Tigo’s RSS Transmitter to Tigo’s UL-certified TS4-F (Fire Safety) units. The RSS Detector is used during installations to verify string voltage and that the TS4-F units are receiving the rapid shutdown keep-alive signal from the RSS Transmitter. This is the handheld, failsafe tool that PV installers use to confirm that PV systems are compliant with National Electric Code (NEC) 2017 690.12 rapid shutdown specifications and supports the SunSpec-defined signaling for rapid shutdown.
