Ring Siren doesn't recognise it is hardwired

Had an electrician install the Ring Outdoor Siren, with batteries and hardwired, however the app doesn’t recognise that it is hardwired. Have checked that the wires are in the right way. Have not used a Ring Plug-In Adapter (2nd Generation) but a generic adapter that does the same thing. We checked that the voltage/polarity is ok.

All help gratefully appreciated. Thanks

Hi @jds6. If you have your Outdoor Siren hardwired to existing wiring on the home, it needs to be installed according to the instructions here. Regarding the adapter, we cannot guarantee a third-party adapter will work properly. The Outdoor Siren’s hardwire terminal block supports the Ring Plug-In Adapter (2nd Generation).
