Where can I find a siren that I can mount on a crane to use in emergencies?

I have a jobsite that encompasses a few acres. We have a tower crane that is about 140 feet above the site. I want to purchase an alarm or siren that will be loud enough to alert the entire site in the event of an emergency.
