ACA P-15 Siren Test | Alert | Downers Grove, IL | 5/5/26

Went to the chicagoland area to record one of the remaining non P-50 penetrators left in the area. I chose this Referbished P-15 located on 4049 Earlston Rd. Note how this unit has two tags on it. seems like this unit used a ACA P-15 core while the back cover is from a RM-127. On the same day I saw that the Allertorator at the Main street fire station was replaced by a T-128 which means this and the other Penetrators in this system are on barrowed time.
