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.

Claims

1. A security system adapted to monitor a product that requires power to be operational, comprising a control module, said control module being adapted to generate an alarm event based on an alarm signal;

at least one splitter box, said splitter box being communicatably coupled to said control module, wherein said splitter box is adapted to store at least one data bit, and further wherein said splitter box is further adapted to generate said alarm signal;

at least one sensor; and

a sensor circuit coupled between said sensor and said splitter box, wherein said sensor is adapted to change from a first state to a second state,

wherein at least one of said at least one splitter box is coupled to a power supply, and said security system further comprising a power adaptor coupled between said splitter box and the product, said power adaptor being adapted to supply power from said splitter box to the product.

2. A security system for monitoring a product that requires power to be operational, said security system comprising:

a control module;

one or more splitter boxes coupled to said control unit;

a power supply coupled to at least one of said splitter boxes; and

a power adaptor coupled between said splitter box and the product for supplying power from said splitter box to the product.

3. The security system of claim 2 further comprising a sensor adapted to be attached to the product;

and a sensor circuit coupled between said splitter box and said sensor.

4. The security system of claim 2 wherein said power supply is coupled directly to said at least one splitter box.

5. The security system of claim 2 wherein said control module is coupled to said power supply and is adapted to supply said power to said at least one splitter box.

6. The security system of claim 2 wherein said power supply is adapted to supply power at a single power voltage.

7. The security system of claim 2 wherein said power supply is adapted to supply power at a plurality of power voltages.

8. The security system of claim 7 wherein said power adaptor is further adapted to supply at least one of said plural power voltages to the product.
