Novacom Wireless GNS-Minitrack equipped with galvanic isolation of input and output. When the state of the input signal changes, it is possible to send a message about the case to the indicated phone number or via GPRS. The main purpose of the input is to trigger vehicle control. The regular alarm output has the ability for remote control, either through GPRS or CSD, and in DTMF mode. Using DTMF mode allows you to enter a phone number installed in the SIM card device and change the state of the output. The main purpose of the output is remote control operation of the engine lock, remote engine start, or vehicle heating system. The input, output, and power circuit of the device are protected against short-term overvoltages up to 50 V.
