Here in the county that I live in, Its a weird setup because the Southern portions of the county have very few new sirens (Federal Signal 2001s) and have mostly older sirens. (Multiple Whelen 3016s and a few Federal Signal 2T22/3T22s)
The northern portions of the county however have newer sirens (Federal Signal 2001s And Federal Signal Modulators) Anyone have that weird type of old/new setup?
