Other than the family dog, the most basic burglar alarm is a simple electric circuit built into an entry way. But if somebody opens the door, the circuit is opened, and electricity can't flow. This triggers an alarm. In an open-circuit system, opening the door closes the circuit, so electricity begins to flow.
