Tigo 400-00900-00 RSS Signal Detector

Tigo RSS Signal Detector

The Tigo 400-00900-00 RSS Signal Detector is a handheld, battery-powered diagnostic tester designed specifically to detect the power-line communication (PLC) keep-alive signal broadcast by Tigo RSS Transmitters. By holding the detector's sensor face directly against a TS4-F, TS4-A-F, or TS4-A-2F fire-safety unit, or along the insulated DC string conductor, installers can immediately verify whether the rapid shutdown signal is reaching that exact point in the circuit.

Powered by 4 standard AA batteries, the tool provides immediate physical feedback through a solid blue power indicator, a blinking yellow detection light, and an audible tone when a valid keep-alive signal is confirmed. This allows technicians to pinpoint open circuits, verify conductor continuity, and ensure full NEC 690.12 rapid shutdown readiness on-site without cutting conduit, stripping insulation, or contacting high-voltage DC terminals.
