Note: If I put the rotator and horn on. 1- I could not get the garage door to go up and 2- I never get the machine out of the garage it would be to TALL. And to put it outside in the weather!? Not on my life unless it goes up on a pole.

Here is the Thunderbolt That I have been working on all last winter and spring.

For anyone who has never seen one here is a Thunderbolt Control Pannel (Single Phase).

Correction hower's were BELT driven Allertors were chain driven. IF they were installed 53years ago they were called Moble Directo's than and they came in dual tone they were 10/12 port federal rotors They just are not many left around. Some of the early ones did not rotate. or you could get the mod...

sure took a while before the siren went off

The 500 Single tone is a STH turned on it's side and having a horn I bet it will be the loudest
