ARCHIVED: Mystery Sirens (2008-3/2021)

[Ziginox]

Why would there be conduit running into a vent? Look closely at the bottom right side of the housing where it meets the pole.

Exhaust blower. There's no way that thing is a siren.

[Trevor]

Why is there an eyebolt on the top of a vent? Unless they just got really redneck and put a shroud over a smoke pipe or something. Maybe the original vent fell off so they found an old siren and borrowed the shroud, lol.

[Mark N]

Look in the middle of the bottom of the siren/vent. It looks like a motor or something

[Brendan W]

If it was a vent, then why would it have a maintenance bucket on the pole?



I think it may be one of those Decot variants I heard about that are in Sacramento.

I think it may be one of those Decot variants I heard about that are in Sacramento.

There's also a few in the San Jose area, and at least 1 to the southeast of Barstow.

Here's a good one for you guys. I was in Fort Leavenworth this past weekend and seen these everywhere. Leavenworth County has a system of Thunderbolts and 2001s on Fort Leavenworth, so I assume these are just some "Giant Voice" system like Fort Riley has with it's ATIs.
The older one really looks like someone put vents on four sides of the pole. The newer style one looks like a cross between a Whelen and an ASC i-Force.

Your mystery array is an ADT Clear Warning system (yes, that ADT).

It looks like ADT has left mass notification as quickly as they entered it; I can't find anything about ADT's commercial unit anymore. I tried seeing if any other Tyco subsidiaries picked it up and I can't find anything other than that SimplexGrinnell resells ASC and Cooper products for giant voice mass notification. Thankfully, all the literature is still available.

I posted this in the Ft. Benning thread, too, but I also put it here so there's a stickied record of this.

Meanwhile, as for the other electronic...beats me. Never seen anything like it.

The siren on the military base that resembles an iforce with the "Mystery Controller" is a Federal Signal MCP. As for the siren head its self, i have no idea.

Although I can say that controller is NOT a Federal MCP. If they're newer than the ADTs, they're well into the UV era (which the controller is absolutely not). And besides, I've never seen an MCP with metal shaping/construction like that. The conduits are also in the wrong place, as the conduit from the battery box to the electronics cabinet is on the right when looking at the MCP head on (so left from the rear, which we are looking at) and the conduit to the speaker array is in the center. Here's a great example of an MCP, credit to Ian:



Compare to the mystery controller:

Look at this ADT PDF @ page 4:

ASC I-Force
Looks like they used MS Paint to fit it in there.

My bad, MC controller, not MCP. The MC came before the MCP so it is definitely from quite a while back.

Look at this ADT PDF @ page 4:

ASC I-Force
.

Definitely an I-Force, It looks just like the one on the first photo to the right: http://www.americansignal.com/products/ ... s/i-force/

I've got a good one for you guys...
