Tigo Rapid Shutdown Signal Detector (SKU Part Number 400-00900-00)

When it comes to your solar power system’s rapid shutdown capabilities, you simply can’t take chances. Should a rapid shutdown fail, you could expose maintenance workers, emergency responders, and even your own family to errant electrical currents, which may prove deadly. The Tigo Rapid Shutdown Signal Detector acts as a failsafe to ensure that your TS4 rapid shutdown devices are receiving a proper signal and will function correctly if needed.

Your module-level TS4 units help to disconnect and de-energize each individual panel in an emergency or during maintenance. They receive a constant “keep alive” signal from your Tigo RSS Transmitter. If that signal is lost—such as in a power outage, natural disaster, or when you disconnect the power manually—this triggers your TS4 units to initiate rapid shutdown on every panel. The purpose of this signal detector is to function as a failsafe testing device. It is used to determine if the connected TS4 units are receiving the necessary keep-alive signal from your transmitter, confirming that the rapid shutdown systems will work properly.

This type of signal detector is primarily used by installers, and work by sensing the power-line communication signal given off by the transmitter. The installer positions the detector’s sensor within 2 inches of a TS4 unit, and if it detect a signal, it will provide immediate audible and visual feedback; the signal detector’s LED light changes from blue to yellow and an alert sounds, confirming that the transmitter and module are communicating properly. The Tigo Rapid Shutdown Signal Detector is compatible with Tigo’s TS4-F, TS4-R-F, and TS4-A-F units, and helps to bring your system into compliance with the NEC’s rapid shutdown specifications.

For installers, incorporating Tigo’s signal detector into your installation and testing process for Tigo devices can allow you to quickly and easily verify communication of rapid shutdown signals, improving the reliability of each system you install. And while a signal detector like this one may primarily be used by installers, it can be a useful peace of maintenance equipment for homeowners as well, allowing you to verify that your system’s rapid shutdown feature is functioning as it should.
