clifford matrix 50.5x sensors

Hello, I have recently gone to a Clifford store in NYC to install 50.5X security system. I don't live in NYC anymore and cannot go there to ask a question. The system is very sensitive to shock and whenever a track drives by my car, the alarm goes off. Is there a way to adjust the sensitivity of the system so it does not wake up people at 2 a.m. in the morning? Thank you for your help.

I've checked the manual and I haven't been able to find anything.

In the manuals for the 50.5x it does not offer a section on adjusting the shock sensor.You will need to locate where your installer placed your shock sensor first.Once you do that it will have a dial on it that you can turn either clockwise or counter clockwise.You will want to turn the dial counter clockwise to decrease the sensitivity.Turn it a little,close your door,then arm your system,wait about 10-15 seconds,then tap on your vehicle to see if it's to your liking.Lighter strikes will give a warning while harder strikes will instantly set it off."ole blake"
