(Analog) Whelen WPS-4004 | 1 Min. Alert & Ambiance | Tulsa, Oklahoma | 11/26/25

At 12:00:04 on Wednesday, November 26th, 2025 the City of Tulsa conducted a weekly test of their Outdoor Warning Sirens which consisted of a 1 minute and 10 second Alert.

About a month ago I had scheduled to meet at this unit today with a Tulsa metro enthusiast but he ended up not making it. I was already going out west today anyway so I still stopped for the test along the way. Regardless, another Tulsa analog has been uncovered, which is cool. Getting closer to having all of the 4004s in and operated by Tulsa documented
