Please help me by adding sirens to the list that are classified as rare, IMO at least <10 in existance. I don't know which might be classified as the rarest siren.

The three CTI models...is the SMO-15H this one?



There is one of these and another in Okmulgee, Oklahoma. I've been trying to figure out what they are for awhile. They also had one that was replaced by a 2001. I know what you're thinking right now, and they didn't let me have it.

Just for kicks, here is a pic that I got the same day of the only CTI SMR-15 known, in Bixby. Yes, they are very small sirens.



I don't know of any SMO-15's out there. The two "mystery CTI's" in Okmulgee and the one in Bixby I believe are the only ones to exist.

I'd say the 550-AT is pretty rare. I would also say that the 9/9 port 40/50 HP sirex is more rare than the siro-drone. There's plenty of those around. Also the super super old ACAs in the brochure. Those were all real sirens, and we've only found a couple of them.

I have both of these in my immediate area!

[Urbanexplorer]

Fyr-Fyters, some of the first electronic sirens, are few and far between.

I'm not sure if you could count Werden Electric's P-10s/P-15s. Perhaps another guy from Cincy can explain what the difference is between a Werden siren and an ACA Penetrator.

[Archon]

Than there is the 6/10 Decot I have only 1 was ever made

[ACCWA]

All of your collabs have been added to the list, it's ever-so expanding at a high rate. It's probably going to be larger by the end of the year.

Model2, i just now added yours.

[Model2]

Both rotating and omni-directional CLM's.

[SoundOff]

There was the omnidirectional 8-square horned siren designed by a Southern California Edison engineer (some refer to it as a "Toshiba" siren) which, as far as I know, were only used in San Onofre Nuclear Generating Station's community alert siren system from the late 80's to 2005 when they were replaced with the current Whelen system. I have no idea if any of them still exist now.


The T-Bolt 2000 in San Dimas was removed sometime around the end of 2009. There may still be one more behind Windsor hills elementary school judging by the pictures on http://www.wirechief.com/sirens/w4.htm since it appears to be the same setup as the one in San Dimas
