Your Ting sensor and service are compatible with - and not impacted by - DC systems such as alarm systems, doorbells, routers, and other low voltage systems.
Ting detects electrical arcing that is often a precursor to an electrical fire. Such arcing is more likely to occur at high voltages on the AC side of transformers that produce DC power for the aforementioned items. Ting has detected fire hazards in DC transformers in several homes and has prevented the potential fires that could have resulted from these hazards.
Note: Ting is not designed to monitor for electrical faults on the DC side of solar/battery/EV systems. Most everything in your home runs on traditional AC electric power, which is what Ting is designed to monitor.
