Viking Electronics' LVR-1 - Line Verification Relay (LVR) is useful on analog (POTS) single phone lines and eXtensions that do not have a method of monitoring the status of the idle phone lines. Phone lines can go out of service at any time and without any warning. You could be paying monthly fees for phone lines that are not in service and not realize it. The LVR-1 can be a real money saver for your customer. Think Elevator Phones, and Emergency Phone etc.
The LVR-1 Single Line Verification Relay monitors the voltage on an analog phone line. When that voltage goes below 2 volts for a programmable time, an on-board relay is activated. When the voltage of the phone line goes above 2 volts for the same programmable time, the relay is deactivated. Selectable times are 5, 10, 15 and 20 seconds. By using a timer, the LVR-1 makes sure that the line is dead before actuating the relay. ed/hb
The LVR-1 is powered by an included 12 volt DC power adapter and has either a RJ-11 jack or a terminal block for connection to the phone line.
