This is the April 2023 siren test in Farmers Branch, Texas. This particular unit is located on Senlac Dr at Valley View Ln. This siren is equipped with UltraVoice & ThunderMod which was installed by Goddard Enterprises sometime around 2015. Farmers Branch tests their 8 outdoor warning sirens every first Wednesday at 1:00 PM CDT, weather permitting. If it is overcast, the sirens will not test.
