(Special Tone) Federal Signal Modulator 4016, alert - Nichols Hills, Oklahoma 6/16/18
Posted: Sat Jun 16, 2018 6:51 pm
Well, this is one of my favorite videos in a while! The MCP controllers on this and the other modulator was recently replaced, and the sirens are now running the steady alert signal again. Anyways, this siren is set to 750/920hz, a very unique sound! I hope you all enjoy! This siren was impressive, especially for just a 1600W omni-directional siren. More videos to come involving Nichols Hills in the coming weeks.
