Use the LVR-1 Line Verification Relay by Viking Electronics to monitor analog line status with relay activation for triggering auxiliary security and notification devices.
Monitor analog phone services such as a POTS line, an analog extension of a PBX, and an ATA port on a cable modem or a VoIP phone system’s ATA.
If service drops on the monitored analog line, the line verification relay will activate triggering auxiliary devices to notify you of the outage before it becomes critical.
