A security system uses sensors at every door and window which will set off an alarm if any one of them is opened. There is also
a keypad by an entry door to turn on or turn off the system. Describe how these components can be wired in a combination circuit to provide the needed security.

Now the console or keypad or the main components the power on or shut off the devices and the remote or sensors are the secondary parts but they are needed to help the console or keypad figure out what they are doing.
