Hello all, Olathe ks has all 2001s, those include 2001 SRNs and SRNBs and 130s. Originally Olathe ks had round back 2001 SRNs but those were replaced in 2016-2017 with 130s. So where A 130 sits is where a round back used to be. in fact Johnson county replaced almost all their old sirens with 130s, those that were replaced include (thunderbolts), (XT22s) and the affomentioned round back 2001s.
Here's a video of an SRNB in Olathe ks https://youtu.be/-QyVUbxOqc0?si=4a_qeEKomK8mUkba
