Penetrating the Penetrators

[nevnick]

As you've probably already seen in my first post, I talked about the sirens in Billings. They are all ACA Penetrator-series sirens. I talked with some city people recently and they said all the P20/RM130 sirens in town were mostly installed in the late 1980s to early 1990s. We had Thunderbolts before.

Basically, the Penetrator was the successor to the Allertor, if I remember correctly.

I know a little bit about the Penetrators now because of this chat that I had. I don't think that they are still making them, per the ASC site.

So as a result of all this research I've been doing, I've got a few questions. Sorry to bore you with all of them...

--When did they quit making 'em and why?

--What siren type succeeded it?

--When did they first come out?

--What other cities have them?

I'm guessing that the T-128 was the successor to this model. Nothing wrong with that! T-128's are great sirens, too.

If those have battery backups, then they are RM-130's. That was between the P-10/15/20 series & the T-128.

The Allertors were made from WWII to about 1990. They were a seperate line up, and lacked battery backup.

I don't know when the Penetrator series started. I believe they had both single & dual tone models. They also went on to around 1991. Other here will know better.

The actual P series & Allertor can be found all over. There are some P series in the area of the old Rancho Secco Nuclear plant, nearest to me.

Take a look at the Siren Archive:

I don't include the P-50 with these since that became the T-135 later on, lasting until very recently.

ASC made the penetrator untill 2000 than the design was sold to werden siren he still makes them to this day. The change over for shrouds started in the 70's I have a 1976 Howler with the newer shoud.

Wausau WI Has a 2000 ASC Penetrator. Manatowoc WI has a 1997 one
I have a ACA 1987 one

Aren't Werden's sirens all made to order? I'd imagine he doesn't have nearly a big enough factory to make them at the scale that Sentry, ACA or Federal does.
