Hello, I am an aspiring Firefighter (currently a computer programmer) and I have developed a simple PASS alarm simulator for Andriod Phones. It works by using the phones accelerometer to measure movement to initiate the alarm stages. It is currently in its first beta build and I hope to add more features in the near future. Please feel free to give it a try, and if you like it, I would ask that you give it a nice rating in the app store.
Apologizes to IOS or Windows Phone users, I have build versions for both those platforms, but I have not yet released them into their respective stores.
