How is a panic button typically wired in alarm systems?

A panic button is typically wired as normally open in alarm systems to ensure that it only activates the alarm when needed. A normally open configuration means that the button is in an open state when not pressed, and the circuit is completed, activating the alarm, only when the button is pushed. This design is crucial for effective panic response, allowing the user to trigger an emergency alert without any inadvertent activation.

In contrast, a normally closed configuration would keep the circuit closed until the button is pressed, which could lead to unintentional alarms if the circuit is disrupted. The other options, such as alternating systems and integrated circuits, do not specifically pertain to how panic buttons are wired in standard alarm systems and are, therefore, less applicable for this context.
