? wiring vans stall warner

I'm not having much luck searching so....

I want to hook up the standard vans stall warner (with or without it's circuit board) to the dynon system but I'm not sure how to make that work. (I considered wiring it to the GMA245 or just the headset jack itself but I'd like more from it if possible)

I'm sure its capable of sounding an alarm and a visual warning but I'm lost on how to do that with only the single wire going to the stall switch. I'm in the process of wiring the EMS220 so now's the time.

Reviving this thread. Anyone know where the output should be connected into a Dynon system?

I don’t know the answer to the question. But if you have Dynon’s AOA system (built into most of their products these days) and the pitot tube with AOA pick off, use that instead. It’s vastly superior.

Yes, I have it. I want the stall switch connected as a backup.
I suppose the best way is to use a buzzer so it's completely separate.
Anyone know what buzzer should be used?

Good luck

I echo what Bob says. I thought, too, that I'd install the stall warner tongue, and hook it up to a discrete input on my G3X, and I'll have both the stall warner AND the AoA. More = safer right?

Not necessarily. Currently my stall warner discrete triggers the G3X's warning annunciator, which lights up a light on my panel and plays a steady waning beep. Problem is, it activates too soon (at too high an airspeed), so I've got this flashing light and beep blaring at me like I'm in a casino, from short final through touchdown. Very distracting and annoying as I'm trying to build proficiency and do phase 1.

Yes, I know with some more fiddling, I can eventually bend the tab just right so it triggers exactly at stall, but then again, I can also just disconnect it and rely on my AoA.

Maybe it would be easier to connect the stall switch and not mess with the circuit board. The stall switch is just a normally open switch that closes to ground.

That's how I did it. I chucked the circuit board and attached it into the EFIS discrete input.

On the Van's RV-12, the stall warn vane switch is connected to SV-EMS-220 37 PIN D-SUB pin 11.

ACM

I asked Advanced Flight Systems.
Response below. Probably the route I will go.

"Larry,
If you want an actually useful stall indicator you should wire the audio from the controller. If you skipped the controller and wired the reed switch direct to the EMS yes you could have a stall indicator on the EFIS, but it would just be a little light on the engine monitor page with an optional audio warning, which will say "engine monitor" -- not terribly useful.

Wire the audio from the controller to pin 7 on your ACM GPS Navigator connector. Since you don't have an IFR navigator, we'll just have you hijack the GPS audio output, which is already wired through the ACM and out the intercom harness. If the stall controller should happen to have an audio ground as well, you can use pin 15 for that."

My circa 2010 rv10 kit (I forget which sub kit) came with a ‘stall warning buzzer’. It was, literally, a Radio Shack part (still in Radio Shack packaging). I installed it, rationalizing that on my first flight (or two or three) the AOA would not be yet calibrated. But, with good noise attenuating headphones, I could barely hear the buzzer on landing. It works, but you have to listen for it.
