I'm curious if anybody knows if you can use this standalone without an alarm. From what I've read it looks like you can, but before I drop 90 bucks on this just to use for a prank I need to know it will work for what I need.
Basically I just want to know if I can record a message on it and then feed it a 12v signal and have it blare when it see's 12v...or relay it if it has to be open.
