Provo

In November of 1953, Provo installed a Thunderbolt 1000 on the fire department, located at 75 S 350 W. This was purchased for $2,500 (almost $35,000 in 2024), and accompanied a smaller siren installed at the Union Pacific Railroad Shops, presumably a Model 2, which is no longer in place today. These were their first sirens since the early 40's, when they experimented with a system of steam whistles and smaller sirens. In February of 1971, the Thunderbolt was moved to the new fire station, which would be it's final spot, as the building were demolished in February of 2023 with the siren still in place. It was then shipped to Utah Steel with the rest of the building scrap. The company in charge of this demolition was A-1 Abatement, and it is worth noting that the company declined to work with an additional party with requests to preserve the siren, even when additional funding and equipment was offered.

The siren ran occasionally for civil defense drills and tests, and was eventually switched to annual testing, participating in the state Great Shakeout Drill. It was recorded for a few tests, with the last test finally capturing a full run, seen here, after the blower was turned back on. This was its last test before demolition. Serial number T-384, 384th Thunderbolt stamped since the start of production in 1952.
