DSC 3G3070 Cellular Alarm Communicator

This device is a DSC 3G3070-RF Universal Cellular Alarm Communicator manufactured by Digital Security Controls (DSC). ​Key Details & Function ​Primary Function: It connects a residential or commercial alarm system to cellular networks (HSPA/3G) to transmit security and fire alarm signals to a central monitoring station. ​How It Works: It acts as either a primary communicator or a backup communicator for traditional landline phone connections. If the landline fails or is cut, the device routes the alarm signal over cellular networks. ​Compatibility & Features: It is designed for standard security systems using the Contact ID transmission format and includes regulatory approvals (such as UL, ULC, and California State Fire Marshal listings) for fire and burglary signaling. ​Note: Because this unit relies on 3G cellular networks, which major telecom providers have phased out ("3G sunset"), it can no longer send signals over cellular networks unless upgraded to a modern 4G LTE or 5G communicator.
