Directed 506T

works well, adjustable, and easy install, especially for a first time installer. 6 months old and no issues thus far. Definately recommend to others.

I feel this is a must have for every basic alarm install. Whether someone is tapping or smashing your windows, this will trigger the alarm instantly. If you leave your phone or something that makes noise in your car, it will trigger it too. I found my phone that way a couple of times. I even leave my phone inside the car, and know when I get a missed call or texts this way.

This is the second glass sensor that I have had installed by professional within two months of purchasing the Viper 5902 alarm. The glass sensor consistently gives a glas sensor active warning upon arming the system. Moreover, the glass sensor consistently goes off once set.

I can pull into the garage, arm the system and in less tahn 15 the glass sensor has triggered the alarm. It has been to the installer eight times for adjustment, and twice after the installer, installed a new glass sensor.

The sad thing is the installer told me not to buy the glass sensor at the time of purchase. I should have listened, now I have to deactivate the glass sensor everytime I arm the alarm.

Easy to install, good, sensitive and very small, and price its great.

I installed this with a python 533 and works like a charm. No issues at all very easy to install. Great product.
