Whelen XXXX-R + PICTURES

Longmont has 3 of these units. (That I've counted)

You know, looking at that thing... that rear horn bracket is ACA all the way. The rotating Alertonic series use this horn bracket/speaker driver holder, never seen a Whelen with that design... but I have never seen a 3016 or the 4008.

I have never seen this kind of siren before . And no offense, but that siren looks to have been set up as unfinished. Regardless of whether or not that it was designed to be that way, I would feel much more comfortable if there was exterior plating on the top,bottom, and sides of that siren head.

One does not "paint" fibreglass. It is impregnated with color, which is why you see all of the yellow ACA and whelen sirens fade after a few years.

Actually, the exterior coating of the Whelen sirens is a material called Gel-Coat. It is the same exterior coating that is used on the Community R-Series weather-resistant horn-loaded loudspeakers. Basically, it is the resin component of the fiberglass, mixed with pigment. It is not paint per se, but the concept is similar. Unfinished fiberglass leaves the fibers visible through the resin. At least, such is the case with this particular method of forming the fiberglass. Gel-Coat can be polished to a high gloss, as can be seen with the Community WET series, as well as all the fiberglass horns used in Community loudspeakers.

Well guys, I have your answer as to what this is. I was up in Luzerne County, which is near the Susquehanna Steam Power Plant (nuclear). They used to have a T-bolt system, the T-bolt system is still up.. but there is one of these next to them. Control box was marked.... you aren't going to believe this.. but that is an ATI. Saw it on several different boxes at different locations.

So now they're trying to compete with Whelens in their rotating product line. The ATI siren, however, only has four speaker drivers. I wonder if those are the 100W ones that they have been using or whether they have found someone to make a knockoff of Whelen's drivers that could handle 400 watts.

That's one of those rotating ATI sirens. I saw one on another post on this board.
