This section is just an assortment of siren pictures. Some are recent, some were sent to me by fellow siren enthusiasts and some are 20 year old pictures I took when I first got interested in this stuff.

Denver Siren McKinney Texas.
This old monster was sitting behind the former main fire station in McKinney Texas. It is about 6 feet long and 2 feet wide and I bet it weighs a ton. It has a iron base that it is mounted on a steel frame with the little roof protector on top. The name cast into the base is "Denver Siren." I was able to flip the motor cover up to reveal a 5 HP 3 phase motor.

Sentry 20v2t siren Allen Texas Sentry 20V2T Allen, Texas
This Sentry 20V2T has overlooked the intersection of Bethany and Jupiter in Allen Texas for about 20 years. I didn't realize how rare of a siren it was until I e-mailed Scott Yarberry at Sentry siren about it. Here's what Scott had to say about this siren....
"Way to go, you have found one of only about 50 of the square horned 20V2T’s made in the early to mid 80’s. These were only produced for a short time and were scrapped due to the time required to produce the horns. The rated output was 128, and most were shipped with the horns extended (which made for a huge crate). If there are more questions we can answer, please let us know."
This siren will be taken down in the next few months. Allen just got a system of electronic sirens that will replace their old assortment of classic mechanical sirens.

Fredericksburg Sterling SirenSterling Model "M" Fredericksburg, Texas.
This old Sterling siren is mounted on an old concrete water tower in Fredericksburg Texas. I took this photo in July of 2001. When I was in Fredericksburg in July 2003 this siren had been disconnected but was still on the concrete tower. The original Sterling Automatic Control was still in place in 2001 but was gone in July of 2003. I think the city was still using the siren up to the time it was disonnected. It looked like it was still operational to me when I took the photos in July 2001. See the Sterling Controller Below. Click the photo to see a larger version.

Sterling Siren ControllerSterling Siren Automatic Control
This controller was mounted on a telephone pole across the parking lot from where the water tower. The box was unlocked so I opened it to get the photos. I have a copy of a 1928 Sterling Siren catalog with a photo of this controller in it.
The thing appears to operate by turning the cams on the right of the mechanism. I couldn't see what kind of contacts were behind the cams. I didn't get a good enough look at the thing to see how it operates. I believe that is a remote control phone relay box in the lower left of the photo.
