The Siren Board

I've seen people talk about the siren systems in their communities, so I decide I'll do the same.

I live in Midland County, Michigan in the City of Midland. The county and city, from my knowledge has one of the largest American Signal Systems within the state, as Michigan tends to be a predominantly Federal Signal dominated region.

There are two siren-types in the system: ASC RM-130s, and T-128s. The RM–130s are the original sirens. T-128s are found located throughout the city and rural areas of the county.

Tornadoes don't tend to be a major hazard since the City of Midland is located within the river valley. The largest tornado was a EF2 back in 1999. Chemical emergencies are a very big risk as Midland is the international headquarters of Dow Chemical, and Dow maintains a nuclear reactor.

It's not impossible that Dow bought the sirens for Midland County or contributed to the cost which could explain why they are ASC. Municipalities in Michigan tend to go for Federal Signal (largely because of WSS). Sentry, ATI, and ASC sirens tend to be uncommon in the great lake state. Whelen seems to be making inroads in some areas though.

American Signal LED Warning Text displays do exists near the plant, and based off the general locations of the sirens, they tend to surround the plant. I really wouldn't doubt that theory.

I was just in Midland yesterday and didn't notice any sirens; I guess I wasn't looking hard enough. I'm at CMU right now and recorded my first siren test on Thursday, and now I'd like to go hear an electromechanical siren in person since Mt. Pleasant's sirens are mostly Vortexes with a couple Hornets...nothing fun. When does Midland test their sirens?

Midland tests it sirens the first Saturday of each month at 12:45 p.m. A growl test is conducted every Saturday at 12:45 p.m.

Testing Procedure

NOTE Midland has a history of testing early, so ensure you arrive early.

Thanks for the info.
