Siren/ararm noise inside/under dash after startup

[Armando Diaz]

Anyone know what this is from or the cause? After I start the engine every single time a few seconds after a siren/alarm turns on inside. It is not coming from the speakers but under the dash or radio somewhere. It chimes likes 7 times and it stops. I just got the truck a few weeks ago from the dealer brand new. I posted a video of what it sounds like on youtube.

 

P.S dont click on the link directly but rather copy and paste it into the browser or else you cant view it from some weird reason
