Thanks for your reply.

So, basically you're saying that there are 4 different timing wheels you have to have to have the 4 different signals?

If it's a federal signal, its going to be loud.

If you know it's loud, wear hearing protection!!!

Where is the one 1003 located?

Jason says that there is a 612 for sure.

Does anybody know how to change the coded signals in the thunderbolt 1003 from: Steady Hi-lo Wailing Hi-lo Steady Pulsed Wailing Pulsed I know that to make a pulsed signal, you have to connect both solenoids to one half of the flasher, correct? I am not sure how you change from steady to wailing. Al...

The motor and controls sound great.

Sounds like it's time for a new DTMF 2-way activation system by ASC for the sirens.

ASC's are universal, to my knowledge, and FSC's are just for the new sirens.

The solenoids just need to be rebuilt (new springs, grease, etc)

I love how the flasher is connected to the time delay relay!!!

What does SRN/SRNB/DC/AC/130 even stand for anyway?

You lucky man!!!

The last time I've been to monticello, it was surrounded by 2001-SRNB sirens.

Does anyone know how a 3t22 control cabinet works? I am familiar with the thunderbolts, but I don't know about the 3t22.

Specifically, I am wondering about "warble" (whatever that stands for/does)?
