Hey everyone,
As some of you know, the city of Independence, OH (in Cuyahoga County) has a variety of sirens including several 5AT's (technically 7AT's) and two Federal Enterprises Thunderbolt 1000's that were from the original CD system which went up in April 1952 around Cleveland and Cuyahoga Co.
Anyways the 5T's are wired up quite strangely. They are 480V 3 Phase.
They are almost like using transformers or something. Anyone know what these are? I've never seen such a weird wiring setup before. All of them are wired like this. I'd post more photos, but apparently for whatever reason, ARS won't let me post pics over 1 MB.
