My local fire station had a gray Model 5 or 7. They tore down the old fire station a few years ago and built a new one. But the siren didn't go back up

Standardly, fire stations often test their sirens in “Noon whistles” or “Noon Blasts” which at a certain time they will be set off for a few seconds after fully winding up, then letting it wind back down again before ending the test. In some modern controllers, like for the Modern Federal Signal Model 2 controllers, you can set noon blast controls for the siren to test at certain times automatically or for a button to be pressed.
Sometimes, a signal known as “Growl” is used, which involves the siren being turned on until winding up halfway, then winding back down again. Most commonly, allertors and older sirens are tested in these signals. They are not as common as Noon Blasts however.
Sometimes Coded blasts can be sent out by specific sirens to go with the noon blasts, but this is an incredibly rare sight as not many fire sirens have solenoids in them. They do exist however.
Or some test for twenty or so seconds as a “short alert” or “short attack” which is not as common as a noon blast but is more common than a growl test. Our old fire station used to test in this signal for their Darley 3V8 before being replaced by a thunderbolt.
I hope this helped you!

Very rare allertors can have a yelp signal but the manufacturer making those motors went out of business. That is what was used as a fire signal from other posts. My town used to use the town's P-10 but it wasn't recorded if it was ever used. It was moved across the street and disconnected from the fire station in 2010. Now its just used as a warning siren. They test every Wednesday and Saturday.
