Viking Solution Detects Faulty Lines
The LVR-1 monitors analog phone lines for a drop in voltage and activates relay contacts that signal a non-working phone line. When the voltage on an analog phone line monitored by the LVR-1 drops below 2 volts, the LVR-1 begins a countdown timer. This variable length timer can be programmed to avoid false alarms. Once the threshold is reached, two onboard relay contacts activate signaling connected devices of a non-working or disconnected phone line. This same variable length timer is also used to prevent multiple alert signals should the line go in and out of service. The LVR-1 can be paired with Viking’s auto dialers, tone generators and lights for a comprehensive alert system. It can also be used to switch telecom devices with a backup phone line.
