506t glass breakage sensor error

This is a little info I found out about the 506T glass breakage sensor. I was having a problem with that sensor giving me an error chirp when I armed the alarm. Adjusting the sensitivity, moving the microphone, or removing the microphone made no difference. I did a search and found others had this problem as well. I saw one post that said he used an adjustable delay to fix the problem. Another stated it might be the Piezo Pain Generator siren causing the problem. My fix was changing the ground source. The MUX port on the Viper 5901 is constant ground, if you are using that, you should be OK. For ground, I was using the Ground When Armed orange wire to avoid current draw when not in use. When changed to a constant ground I no longer get the error chirp from this sensor. I'm told the current draw is minimal. GWA worked fine for the Field Distubance and the Tilt sensors. If you made this mistake too, and used GWA on the 506T it might be your problem. I'm not saying this will work for everyone, but it corrected my problem. Hope it helps.
