Hi All, Any assistance is appricated. I have a DSC Alexor PC 9155-433 Wireless Alarm panel. http://www.dsc.com/index.php?n=products&o=view&id=53 I am trying to enrol the EV - DW4975 Product. According to the DSC website this product should be supported. http://www.dsc.com/index.php?n=products&o=view&id=88 I have other wireless sensors which seems to enrol with no issues but the EV - DW4975 doesn't seem to be picked up by the Wireless Enrolment option. I have check the frequency in supplied manual and they are identical 433.92. Any assistance you may offer would be greatly appreciated. Cheers Marc
