Thunderbolt 1000AT - Chopper-only test

Yet another run up of my Federal Sign & Signal 4/5 port Thunderbolt 1000AT's chopper, after rebuilding it both mechanically and cosmetically. I haven't finished the horn yet; as you can see it's still stripped of its paint on the outside. This time I ran it up on terminal #2 on the TB-105 chopper transformer (130VAC). Siren runs a short alert (with towel stuffed in the horn to muffle it), and a couple growls at the end with the horn un-muted.

So if you have the RCM panel and you have 240 running to it and you set it on tap 2 it only lets 120 to the chopper?

@rhett443 Close, but it would actually be about 132VAC if running on 240. The chopper transformer is setup to have 230VAC incoming power (which is fed through terminal 7, since that terminal doesn't use the transformer, it just runs straight off of the incoming power), and it starts off at 110V (terminal 1) and steps up in 20V increments up to the full 230V (terminal 7).

At first I didn't think it sounded right, then I saw you take the towel out, lol. I wish I had a Thunderbolt. Nice vid.

Haha yeah, I stuck that towel pretty far down the horn to try and dampen the sound output the best I could, so it wouldn't be that loud in the house or outside the garage. That beast is loud even without the blower, with an open pipe! That horn amplifies the sound unbelievably well; the chopper is so quiet without it but as soon as you add the horn, it gets VERY loud, very fast lol.

it's still the loudest siren on the market without the blower!!!

Lolz! It looks like you just woke up and the thunderbolt was your alarm clock so you went over to it to turn it on snooze mode haha! Awsome video though!
