Lockdown Voice Evac Messages?

My school has a male voice recording for both severe weather and lockdowns. Does anyone know where I can get a lockdown message that sounds like this: “May I have your attention please. The building is in a lockdown condition. Lockdown, Lockdown, Lockdown.”

I just want to do a simulation for one of my demo systems and since there are not a lot of natural sounding voices out there, most of them are very robotic sounding which I’m not too fond of.

What brand is your school system?

Notifier

I’m curious if anyone has seen or heard a Simplex system with a lockdown message. I have been for over a month now waiting on Simplex to tell me whether or not their master database has one so we can upgrade our 4100 at our private school.
