Blueprint for Alarm/alert based on binary triggers?

Never having used a Blueprint up to now, I found a good reason to start exploring:
I am using several alerting automations in my config, all based on binary state changes (lights, motion, doors etc etc)

and, under a set of conditions, fire a set of actions, like sounding alarms, create persistent notification, flash lights, and notify some notification services.

Of course also offer the option to stop the alarm, or even disable the alarm_panel.

Seems this would be a good reason for a blueprint? However, not wanting to invent the wheel, I find myself lost in searching for something like that.
Would anyone have made a fitting blueprint yet (probably). I’d appreciated a link, or suggestion.
