FIELD: electricity.
SUBSTANCE: invention is related to electrical measuring equipment intended to measure the operating time of lamps in light lines. The device consists of a microprocessor, a network modem, a sensor sensing supply voltage transition above zero, which input is connected to the microprocessor input, control inputs and outputs of the network modem, which are connected to the respective inputs and outputs of the microprocessor; a value of the operating resources meter for a light source is stored in the microprocessor memory, the sensor sensing supply voltage transition above zero is used as a time setter generating at its output pulses with a period proportional to a frequency of the supply voltage so that the value of the operating resources meter could be decreased and a message could be sent about the resource ending.
EFFECT: delivery of a signal warning about the resource ending.
