Welcome to the Community, @kalanikaau! This is an excellent question. At this time the Alarm system is a separate “ecosystem” from the other Ring devices. While they can all communicate via the same Ring app, and even be controlled together via the Modes feature, the Alarm’s emergency response is dedicated to Alarm devices.
We recommend using a combination of Contact Sensors and Motion Detectors with your Ring Alarm System to ensure for a true ‘Ring of security’ with Alarm. While the Alarm armed/ disarm modes, siren, and emergency response is only altered by Alarm devices, you can certainly accomplish some great automation options in the Ring app and with Alexa. Feel free to check out our help center article about arming/ disarming your Alarm with Alexa, as an example of what can be accomplished with integrations. I hope this helps!
