The Telguard TG-1 Express TG1LAX LTE Cellular Alarm Communicator provides the ideal solution for residential applications. The TG-1 Express LTE-A transmits full data from security and fire systems to central stations using a nationwide digital cellular network. Today’s modern family commonly chooses to use their cell phone or VoIP service instead of paying for a traditional phone line. This growing trend makes what was once the most common form of communication for the security system unavailable in many new installations. When there is no telephone service available from your customer’s home, Telguard model TG-1 Express LTE-A ensures that critical alarm information reaches the central station.
