HA 2025.1: stopping Alarmo alert on trigger

Background:
I’m using Alarmo. I have a repeating action (played via one of the tablets) stating “The alarm is about to trigger.” repeatedly (it’s the same sentence repeated, to run for about 50 seconds) as a reminder to turn the alarm off (when it’s in ‘away’ mode), before the alarm triggers (60 second delay.)

What I’m looking for is a way to ‘kill’ that speech notification when the alarm goes to the ‘disarmed’ state - say, via the keypad. Doesn’t matter how it was disarmed, I’m just trying to figure out how to get Alarmo (or HA itself) to kill the notification when Alarmo switches to ‘disarmed’ or ‘armed home’.

Is this an automation, or one of the Alarmo actions? If the latter, you’d have more control of it if you made it an automation triggered by the state of the Alarmo entity.

I have something where I have a script that is called and will run until Alarmo is disarmed. It could be an automation also. My Alarmo is called security.
Simply using as per picture…

It’s an Alarmo action.

That looks like it would work well - have an automation, triggered by Alarmo going into a ‘trigger’ state, to make the announcement.
I’ll give this a try when I have the time. Thanks!
