Aprotex teams with Guardtronic, of Fort Smith Arkansas, to provide superior Monitoring for their customers. Guardtronic operates Arkansas' only U.L. Listed and Factory Mutual approved central monitoring station serving Texas, Arkansas, Oklahoma, Missouri, Mississippi, and Kansas. Fully-trained in house operators monitor all systems from the Fort Smith central station, 24 hours a day. Aprotex and Guardtronic have worked closely together for nearly 50 years, the company that became Aprotex was founded by Vernon and Shirley Gilbert, in 1952. In 1959 Guardtronic was started in Arkansas, by several of Vernon's brothers. Both companies are privately held corporations, still Family Owned. Aprotex is capable of monitoring nearly every burglar alarm panel that is manufactured, so if you already have a system installed, more than likely it can be reprogrammed to Aprotex in about an hour.
