Viper 790XV Chirping Relay?

I was wondering if anyone knows if the Viper 790XV brain uses a chirping relay to do the warn away sound.

I'm asking because I hooked up my 508D radar sensor to constant GND, so it's always on and now the warn away doesn't work.

The 508D instructions say:

"If using the 508D with either a 516T-series voice module or a siren chirping relay, it must be turned off while the system is not armed."

All this meaning the 508D must be connected GND when armed for the warn away feature to work.  Is this true?

I shorted the blue and green wires of the 508D together then put them into one of the multiplexed inputs of the 790XV.

Do you know if the 79-XV has an internal chirping relay, meaning I would have to connect the 508D to a GND when armed output for the warning mode to work?

It's a long story, but I had both my 508D and my 507T (tilt/motion) both on the GND when armed line.  Including the starter kill relay on that line, all 3 components were drawing more than 500mA, so the sensors were all acting weird.  So I moved the 508D off the orange wire, since the 507T has to have it to calibrate the tilt.  Now the 508D no longer has the warning mode.  I just want to make sure I need it on the GND when armed for the warning mode to work, before I rip everything apart for the 5th time and add a relay to the orange wire to GND the 508D and 507T.

Thanks for your help.

Thanks for all the help.  My 508D seems to work normal like 90% of the time now.  On some days, the warning mode seems to die out, but I guess it's no bi deal.

I actually tied my green and blue wires on my shock sensor together and did the same to my radar sensor so they could each have their own multiplexed input.  This way when a sensor goes off, I can tell which one by the zone 1 and 2 on the remote.  I didn't use any diodes in this setup though.  Just wondering if I need them if both sensors are isolated from each other since they're on their on mux input.
