Federal Signal DSA Siren Test (Voice & Fast Wail x2), Nacogdoches, TX

0:10 - First Voice & Activation 0:57 - Second Voice & Activation After Tyler’s test on Tuesday I continued the Federal Signal electronic siren streak by heading out to Nacogdoches to record this DSA4x4 on top of the Homer Bryce Stadium at Stephen F. Austin State University as a part of the campus’s outdoor warning system for severe weather and other threats. I had no idea how their test sequence was going to sound (as this system was previously unrecorded) and was pleasantly surprised by the fast wail as that is an uncommon signal heard on UltraVoice systems in the wild. Stephen F. Austin State University tests their sirens on the first Wednesday of each month at 11:55 AM weather permitting.
