Abstract: A security system for monitoring a product includes a sensor coupled to the product that is further coupled to a splitter box. The splitter box includes a first shift register for storing data that indicates whether the product is coupled to the sensor. A main controller unit coupled to the splitter box causes the splitter box to transmit the data and then causes the data to be stored in a table. After storing the data, the data is transmitted to a second shift register disposed in the splitter box. A logic circuit disposed in the splitter box compares the data stored in the second shift register to a signal indicating whether the product is still coupled to the sensor and generates an alarm signal if the product is no longer coupled to the sensor. The alarm signal is subsequently transmitted to the main controller unit which responds to the signal by sounding a horn.
