Multi Signal Siren Map Help

[Crazymincrafter2012]

I'm making a map of coded sirens, like the Fedelcode Model 5OC, the 3 Signal Allertor, 3 signal P-15's, NOT sirens like the 1003, 3T22, and other more common coded sirens. I want this project on my school Chromebook so I can import this to my main computer at the end of the year. Any research, images, and help is apreciated.
