Federal Thunderbolt Siren RCM Panel Test

Here's a video of a test of a Thunderbolt RCM panel. Exciting aint it....
This panel had the wiring from the test switches cut out of it and the transformer removed. I rewired it and this is the first timer test of the panel since I rewired it.

I read in the manual that the blower and rotator relays will drop out for a split second and re-engage immediately, to the point that the motors won't notice it.

@soccerdude7330 Yeah I saw that too after I made this video.

were you running this on 220 or 110?? if 110, fans would of been an interesting means of identifying which was on and off also, that and i think the transformers wouldnt of hummed like they did. the fan motors should add some extra load to balance the humming noise. just a thought thou...

I've had a few RCMs with starters that buzz when engaged. This panel has a new blower starter in it which doesn't buzz. The chopper and rotator starters are original and they buzz like crazy. It was hooked up to 240. I don't know if the starters would even engage at 110. They have 220 volt coils.

Interesting..... Show us that with the 1003!

I hope I can do that this friday. It's supposed to be sunny. We'll see.

That's a different Attack. It is 4 second on, 10 second off, weird. I wonder how that would some.

Yes it's like that on all Thunderbolts. The point of having it on the time delay is to keep the rotator and blower running during chopper coastdown. The main point of the Thunderbolt design was that it was loud ALL the time. The signal stays loud while the siren is coasting down and winding up. With a regular siren it loses some sound volume during the attack signal because theres not as much air moving thorugh the siren then because the rotors isn't at full speed.
