Comments on: Broadmoor Civil Defense Siren full view
Reader comments and feedback for the Broadmoor Civil Defense Siren full view photo.
This image is part of the Historic Photos photo gallery Civil Defense Siren , located on Akard Avenue (between Atlantic and Pennsylvania Aves.), on the East side of Broadmoor Junior High property. (4/2005)<br /> <br /> Tested every Saturday at noon. Loud. Though I never was next to it when it went off, it could be heard all over Broadmoor, South Highlands and probably beyond.<br /> <br /> Appears to be a Thunderbolt 1000 series.<br /> <br /> Pictures and sounds here<br /> http://www.civildefensemuseum.com/sirens.html<br /> http://en.wikipedia.org/wiki/Civil_defense_siren<br /> |

Maybe someone can describe how the actual tone sounded. I don't recall if it was a single steady tone or whatever.

I-S, the specs for the Thunderbolt 1000 say it outputs 125 dB measured at 100 ft.
Also for perspective, the cone is 56" long and the opening ~28"x29". I think there used to be one on top of a building downtown. Wonder where others were located? |

I could hear the one on Akard when I was on Preston loud and clear. That is the only one I knew about but I was riding a bike at the time.

This thing used to rotate. I lived two blocks north of Broadmoor School and it would get really loud and then start to fade. All of a sudden kids would start coming outside and start playing after this. It signalled the end of cartoons on Saturday.

I think the horn produced a steady tone, but it gave the impression of an up and down tone as the horn rotated around. It seemed to take about 30 to 45 seconds to complete one turn around.

Seriously this is how I remember it. I lived about a mile from Broadmoor. The dogs all over would go nuts howling at the siren... Especially our dachshunds. |
