The Siren Board

I was searching around the Utah Siren Map and I found 4 Sentry 10Vs on top of the Copperton Concentrator building (8300 West 10200 South, Bingham Canyon) does anyone know if they're still active? If so when do they test?

They'll occasionally run them for fire drills, to my knowledge they haven't run them since 10/23/2021.
