**Problem solved see below**

Hello, HT

I've ran into a problem installing my Viper 5906 alarm. I believe my 506T audio sensor is bad. I have it and shock sensor daisy chained together per the instructions. The shock sensor works fine but the audio sensor does not. The audio sensor red light will flash when plugging in but when not trigger no matter how high I set the sensitivity. Is there any specific test I can do to verify condition. Am I overlooking anything ? I've checked voltage at the plug and right now I'm getting volts on the red and blue wire.

**Problem solved**
I had to wire the 506T as follows
Red wire-12V +
Blue wire-Alarm Instant Trigger
Ground(Black Wire)- Ground When Armed-Orange wire on DEI alarms.

**My audio sensor microphone was bad. I replaced the microphone and I can adjust sensitivity now and it works everytime.

It's my fault I must have stretched the wire or pulled too hard on it installing it in the center console.



Thanks
Chris
