In the figure there is a configuration that uses a 4-input trigger NAND port, such as 7413, 7414, 74132 or 745132. The value of resistor R1 will depend on the port used, as indicated in the diagram itself. In the case of doors with fewer inputs, just eliminate the 1 k ohm resistor or connect, through this component, the unused inputs to +5 V.
