I think it's a regular 5. It was replaced by the 2001 several years ago but Scott Ham has some videos of it going off on YT, along with the STH-10 in Walnutport. Unless the 2001 is stationary and we are hearing it instead of this siren.Jared Thompson wrote: ↑Fri May 04, 2018 12:23 amI'm thinking that this is a 5T. I may be wrong though. This siren is located in Slatington at the Slatington Volunteer Fire Company off of West Church Street.
