Weird Issue with flow/sequence

So Im trying to make my door bell turn on my siren/alarm, using homeassistant, but it turns on, and then after the delay turns it on again? I'm not really sure.

I've attached an image of what the sequence/flow?? looks like.

I feel like I'm missing something.

Cheers

Picture nice...but a
copy of flow,
name of the platform,
NR and node.js versions
much better.
