Looking for a Notifier Slow Whoop Sound File

Hello, I’m having trouble finding a sound file for the slow whoop tone found in the Notifier NFS2-3030 with DVC. It is seen in this video: https://youtu.be/FDjPJcFb6kU

I have the message all set, but I’ve been looking for this tone for a while, and it’s rather hard to recreate.

I’m aware of that one, it’s very similar but not quite what I was looking for. Thanks though!
