Siren: ASC T-135 AC/DC, 4 RPM, 507 Hz Town: Grand Rapids Township, IL (La Salle Exelon siren #15 Location: N. 23rd Rd. east of Joe Hettel Rd. Test Time: 1st Tuesday of the month 10 AM every month Cycle: 3:40 of alert Other notes: La Salle County did its test weird today. They did a full 3 minutes and then sent out a 2nd activation just after they started winding down, making it sound like the sirens did a little hiccup. It wasn't just this siren; it sounded like every siren in the system did this. Anyways, the T-135 replaced a Thunderbolt around 2008. It also indirectly replaced another Thunderbolt directly to the east and one to the south southwest.
