Clarification for "No permit is needed for smoke and CO professional monitoring"

Every time I include/register a smoke & CO detector to my ring.com, I get the following email. It is unclear what this means. Do I NOT get professional support when one of our smoke & CO detector detects an event that may need local fire dept. support (I do subscribe to professional monitoring, and I've obtained alarm permit)?> Subject: No permit is needed for smoke and CO professional monitoring> > Hi Neighbor,> Thank you for adding smoke and/or carbon monoxide monitoring to your Ring Alarm.> Our records show that you do not need a permit or registration to get professional fire monitoring.> We suggest that you check with your local municipality to confirm any fire monitoring rules for alarm systems. If no paperwork is needed, then you’re all set!
