Can one SMCO600NV-AC bridge via wireless with another? Will the first SMC unit alarm if SM100V-AC units are connected to the second SMC unit and one of the SM100V-ACs alarm? Will the SM100s alarm if the first SMC alarms?

Hi RonR, the SMCO600NV-AC can wirelessly interconnect with other SC5 models (both battery-operated and hardwired versions) via the First Alert app using a Wi-Fi protocol. Additionally, the SMCO600NV-AC can be interconnected with the SM100V-AC model, but only through the hardwire interconnect system. When properly interconnected, if any unit detects smoke or carbon monoxide (CO), all connected alarms will sound. It's important to note that the SM100V-AC is a smoke-only detector and does not include a CO sensor. However, thanks to the smart interconnect feature, if a CO alarm is triggered by an SC5 unit connected via hardwire, the SM100V-AC will still replicate the warning.
