maybe try 154.070. It's listed as the Fire Pager freq for Bloomington on RadioReference.com. Very helpful site for stuff like this.

IIRC Sentry's S.T.A.R. system uses an encrypted DTMF string somewhere around 20 or 30 digits long. I've only heard it once in a video, its quite unusual sounding.

Got a link?

Assuming a dB loss rate of 10dB per distance doubled and using Whelen’s 129dB @ 100’ rating, it would be about 89dB.

I was recording the nooner Bullard in Rickreall when I heard the nooner in the next town over go off- Dallas, an STH about 4 miles away.

More new info! Recently the Camas Valley FD in Oregon restored their Bullard, and posted about it on their facebook. They mentioned that it had a 10HP motor, although I am still skeptical of the given the size and volume of these, and the way E.D. Bullard did the model numbers of their other sirens,...

The way you describe it makes it sound like the rectifier failed and the siren auto transferred to the batteries, which would run it at a lower RPM. Not sure though, as I don't know how ASC sirens handle that.

Update. The model of the Carl Th. Malling sirens previously referred to as “Type A” and “Type B” have now been verified. They’re called 243L and 243S. L - Lille, translates to “small” in Danish S - Stor, translates to “big” in Danish 243L are the ones most commonly found in Greenland and have a sig...
