Robert, as a fellow campanologist I can tell you that they sound nothing like real bells. The closest description I know of are certain English-made electronic doorbells from Friedland which are often sold in American hardware stores, or perhaps the electronic chimes heard in most German school buildings or airports. The worst electronic carillons (i.e. Maas-Rowe) are not this bad.

In Germany, in a school that I was considering to attend, they had three stationary "bullhorn" speakers. Each of them had a different pitch. They would be sounded in succession, the one with the highest pitch going first, with the horn with the lowes pitch going last. I think that they would signal shifts. They did not sound like bells, but were mild and short blasts. They were nice-sounding "bells."

How strange.

Did they face the same direction, or did they broadcast 360 degrees?

Did each sound a different frequency?
If so, maybe each horn was tuned to it's resonant frequency for greatest
efficiency/output.

[SirenMadness]

Those speakers are each facing the same direction - the front lot.

Yes, each one does sound a different frequency.
Firstly, one would do a short and mild blast, with the highest frequency, then the second one would turn on, with the medium-frequency blast, then, lastly, the one with the lowest frequency would blast. Each blast was probably half of a second, long.

I don't think that they needed to be efficient, as the sound output was not really that great.

[jkvernon]

Actually no, the speakers don't sound their own individual frequency, they all sound the dual toned frequency chimes and siren tones. It wouldn't make sense not to test or sound them individually and lose sound output.

Are you talking about the speakers of the EOWS or the speakers that I brought up?

If only I could find my video camera

I think that you had it on Pollak's server.

[quote="Elliott"]Robert,
E.O.W.S. stands for Electronic Outdoor Warning System, made by Federal, and there are two popular models that I have seen, plus possibly a few others to my knowledge. The 612 looks like 6 paging horn speakers on a circuit breaker panel that rotates. /quote]


Also 612 designates that the siren has 6 horns and 12 drivers (2 drivers per horn)
