False Alarm on Smoke Listener

Last night, in the middle of the night, of course, our Ring alarm sounded the fire alarm. We have the smoke/fire listener, but I am almost certain the smoke detectors did NOT go off. We have hardwired/interconnected detectors in every room, and they are very loud and have voice prompts. If they'd gone off we would have known it. Of course by design, Ring dispatches the FD immediately when the fire alarm goes off, and they're right around the corner so they got here quickly. As nice as they are, I'd like to not see them again tonight. Does anyone know what can cause a false alarm on the smoke listener? The ring app reports full battery on the listener.
