Posted By: Jack SmithinThis sensor is the best of the best, I chatted with a young man at Geoarm and he recommended the EV-DW4975 - DSC Wireless Vanishing Door & Window Alarm Contact, i was so happy when i got them and installed them. the only hard part was the programming. I emailed the techs at Geoarm and they responded very quickly and helped me with the programming.. They are the go to people i tell you.. KEpp it up guys!!!!
