Federal Signal Thunderbolt 1000T (malfunctioning)

Run-up of Jeb's (Blue10AEMia) 1983 Federal Signal Thunderbolt 1000BT (series C), with a slight malfunction. The time delay relay ("AGASTAT") has gone bad on the RCM1B, so every time the chopper contactor pulls in, it kills power to the coil on the blower contactor, causing the blower to switch off as long as the chopper has power. As soon as the chopper contactor pulls out, the blower kicks back in.

Video was taken from about 1/4 mile away, in a field behind Jeb's house, right on-axis with the horn.

Wow Even though that is a major malfunction it give us a look at how much the blower helps!

[murrfarms]

@rhett443 Oh yeah, the blower makes all the difference!

@Thunderbolt1000T Yeah, it was directly adjusted on the camera. I'm using a Canon HF-R10 HD camera that has dual-channel stereo microphones built in, but it has the option for an external microphone setup, since it has a microphone-in jack.

I think mine can also go as low as -25dB too if I need it to go that low, but I haven't quite found anything that needed me to set it any lower than around -15dB. I really like basically having a stereo audio recorder and a camera all in one!

@Thunderbolt1000T I believe it was around -14dB, if I remember right. I had been playing with it for a while with different siren recordings, trying to find that sweet spot with different sound levels, and I think I may have found it. This is also the setting it was on when I recorded the latest video of the Whelen Vortex.

This is true, I may see what Jeb thinks about doing that. Although, the best we could do is maybe 30 seconds of each, and that would probably be pushing it.

LOL it sounds funny when it winds down, like someone ripping ass pretty hard haha.

[murrfarms]

@garyhstorms10 Well there's your answer then lol

[Blue10AEMia]

@murrfarms This is about as much as we will be able to get away with unless we happen to set it up the day a tornado comes through.

[murrfarms]

@garyhstorms10 We might do that next time once we get all the bugs worked out of the RCM. I'll have to see what Jeb thinks of it since it's his and is at his house.

Could you run it in Alert and Attack when it is fixed that would be nice you can do a minute of each signal to see if it works right also sounds like a 5/6 Port Model
