Fort Worth, Texas Old Siren System
Page 1
Here are 22 photos of 22 sirens from my first trip over to Fort Worth to photograph their old siren system. More photos on page 2 and 3. There were/are 71 sirens in the old Fort Worth system. There are photos of 34 sirens on page 2 and 13 sirens on page 3 so I have 69 of the old sirens so far. I should have photos of one more siren up 05-23-2005. I'm taking one more trip over to make a "special visit" to one Thunderbolt in downtown Fort Worth. It's the last siren in the old system I still need to photograph.
I never would have done all this if they had all the same type siren in their old system. They have 5 different types of sirens from 2 different manufacturers. The first batch of sirens Fort Worth installed was a system of Federal Thunderbolts, STH-10s and SD-10s. It's obvious looking at the installations of the Federals that these were done all at the same time. I wish I had a date when they were installed but I would guess mid 1950s or so.
An addition of ACA (Alerting Communicators of America now American Signal) sirens was made later. I'm not sure of the date the ACA sirens were installed. Maybe mid-1970s? The ACA additions are Allertors and Penetrators. I believe the Penetrators are P-10s but I'm not sure. Some of the Penetrators are light blue-gray in color. These look like newer sirens to me but again I'm not sure of the age I'm just going by their appearance. Just taking a wild guess I think the Allertors and yellow Penetrators are the same age and the light blue-gray Penetrators are a bit newer. Who knows.
I have yet to find out if the Thunderbolts are dual-tone units or not. I should know this soon though.
