Here is a video of the City of Dallas, TX outdoor warning system running the 90 second Attack cycle. This unit is one of about 150 2001's in the system. This siren is located off of I-30 and Dalrock on Lake Ray Hubbard
How much were 150 of these for Dallas TX. Cities within Hennepin County in Minnesota are getting these to replace their old sirens namely Richfield MN is the latest city to replace and upgrade it's mixed System of ACA and Federal Sirens with these 2001-130s
Seems Rockwall hasn't updated their map then..... Yeah it doesn't show this siren there anymore on Dallas' updated map. They are actually implementing 20 new 130s by next spring.
