Intergrated circuit CA3083 has 5 NPN transistor. They are used in the same P-type substrate. You can use it as PNPN thyristor switch. Their public substrate is used as anticathode. If any button closed switch connected with controlled silicon, the anticathode load relay will be pulled in and the alarm will send warning signal. If any sensing switch on portal or window is colsed by the thief, the corresponding light will be lighten and point out where the thief is. Before the computer resets by cut off the power supply, the warning will keep sounding. In normal times, the circuit does not cost any power. The controlled silicon can support power for the circuit.
