Which code should be used by the detention facility if the system is off-line?

The Emergency Override Line (EOL) is specifically designed for situations where the system is off-line, ensuring that necessary procedures can still be efficiently communicated and executed. In a detention facility, maintaining security and the ability to respond to emergencies is critical. The EOL allows staff to override standard procedures, enabling them to manage releases or other crucial operations without relying on the primary system functioning as intended.

Using the EOL in these scenarios helps ensure that there is a protocol in place to prevent any adverse situations that may arise when electronic systems fail. This solution exemplifies a proactive approach to facility management by providing a reliable alternative during technological downtimes.

The other choices, while having their own specific uses within facility operations, do not address the need for an immediate and efficient bypass system when technology is unavailable.
