Global One Digital LLC

Established in 1969, Central Alarm Signal provides business and residential security solutions. The company offers access control systems that allow entries into the areas where the system is installed. Its card access systems require the card to be passed through a reader, and its biometric identification provides a nontransferable means of identifying people. With the assistance of central alarm signal's design staff, each of these systems can operate as a stand-alone system, or can be network integrated with one or more of the company s access control systems. It also offers various state-of-the-art telephone line supervised, environmental monitoring, and home automation security, fire detection and video surveillance systems. The company s central station dispatch and technical staff offers services 24-hours, seven-days a week, providing security and monitoring services on a minute-to-minute basis. Central Alarm Signal is located in Detroit.
