Aberdeen's EOWS's are mostly on the edges of the city while the Federal Signal 2001 SRN's and one 2001 130 that replaced a 612 make up the core of warning sirens, depending on dispatch they either sound alert with a fast wail, or they sound a alert with a Hi/Lo on the EOWS612's.
I won't be recording anymore of the Aberdeen units until Spring of 2021 due to the darkness that is slowly getting earlier by the day.
AS for Mobridge they have a Federal Signal 3T22 downtown, and at least 2 2001 SRNB models, one by the high school/ baseball diamond and one by the West clinic
