Need help finding a tool to check door and window sensors

My house is pre-wired with door and window sensors. I’d like to go through each circuit and make sure it works. Existing alarm has 9 zones, some tied together (e.g. multiple windows next to each other). I’d like to be sure they all function (and troubleshoot issues) before installing a new system.

This is a basic continuity and resistance test, but doing this on my own and going back and forth to the alarm hub and the windows, doors, etc will be a pain. Is there a tool I can hook up to the wires in the box and then remotely “hear” while I test each zone?
