Your best bet is to take the siren off in parts. Start with the horn and rotator, then blower pipe then blower itself. You're going to need a crane/boom/cherry picker with the appropriate weight capacity. Thunderbolts weight about 1000LBS all together, heard horn and rotator assembly is 300. If you ...

Does anyone know if the Kenwood Country Club tests their T121? They used to have a Whelen hornet at one point.

Either I'm having auditory hallucinations or I heard something at noon. I was inside my house in sharonville but I heard at least a minute of alert. Is it possible that one of the industries in sharonville (I.E. the ford plant, General mills, or GE aviation) have a private siren?

Can we count the Werden B115 and P127? There's only 1 115 in existence and to my knowledge all (?3?) P127's live in Ohio.

I've also seen an SD10 in the same bucket in Cincinnati on a warehouse. Your sirex is probably unused, and mig...

Here's something I found on the old Control booth forums The University Loudspeaker Company was formed in New York in 1936 and was going by University Sound in 1959 when it, along with Altec Lansing, were acquired by Ling Electronics (LTV). In 1963 University moved to Oklahoma where in 1983 it was j...

This a topic listing and discussing repowered sirens. Repowering refers to rebuilding a piece of equipment (such as a siren) with a different engine/motor/controller. One such example is the repowered Federal Electric Type B at Shandon Ohio. (credit to 4j25). Note the new motor mounted in the box ne...
