A better demonstration of my Federal Signal Touch master TM4. This is not the delta but the older model. This unit only has Manual in the middle and Wail only for the flip switch. For a free unit that I had to pull out of the car it came from I'm surprised how well it works. It does the intercession sweep and transition from Wail to yelp back to wail. If anyone would like to see more of it or have questions feel free to ask I hope everyone enjoys.
