In a local municipality, there is a long disused system consisting of what I believe are Federal Model A sirens mounted on utility poles next to the larger intersections in town. These sirens were used to warn of an approaching emergency vehicle and controlled by dispatch. An approaching vehicle would radio dispatch to activate the siren and radio again to turn it off. That’s all the information I was able to get. I don’t know when the system was installed nor when it was removed from service.
The municipality also had a Gamewell system at one point and had the Diaphones (Horns) on one of the stations up until a few years ago, though the system hasn’t been active for around 15 years.

That’s pretty neat… I’ve never heard of such a thing before… Our area just has opticoms everywhere.

All of the lights have Opticom receivers now. Some of the remaining sirens are at intersections w/o traffic lights, just a stop sign on the side road.
Now that I think of it, I do remember seeing a few Gamewell boxes with Model As on top of them. I’m assuming that was still an intersection siren, but I’m not 100% sure. Those have long since been removed.

I think I know of 2 of those. There a siren a a pretty busy intersection with no apparent reason other then this. There’s another one at an intersection very close to a fire station except the fire station already has a siren. (This is the one by the fire station)
