I already have Zone 2 being used by my audio sensor in tandem w/the shock sensor....from the 508D, I connected both the blue and green to the Blue (Zone4) on the H1 harness. But now the sensor doesn't have the "dual zone" effect. Anytime I violate the first field it goes to full alarm...Is it because I have the blue/green wires connect to the same input? Is there a better place to connect the blue/green wires from the sensor?

any time you wire multiple sensors into the same input you should diode isolate. try it if you didnt, post your results.

Oh yeah I forgot about that...But I just realized that the factory harness for the shock sensor has a loose green that instructs you to connect both a green and blue output to this w/o diodes as it's designed for this. So I connected the proximity sensor to the shock sensor and plug the shock sensor into the main unit. Then, I cut the harnes wires to the glass-break sensor and hard wire the ground and power to proper points...A since there in only one trigger for this sensor, I connected to the Zone 4 wire (blue) on the main unit..Works perfect now!! Thanks for your response Gcorrea...

-Also, now I have this problem w/the motion sensor when it rains...the rain drops rolling along the window trigger the warning chirp. I tried adjusting the setting a little lower, but now it doens't trigger when someone comes up to the window.....any ideas?
