An additional way to categorize electrified locks is by which two terms?

The categorization of electrified locks into the terms "fail safe" and "fail secure" is critical in electronic access control as it relates to the lock's response in the event of a power failure. "Fail safe" locks are designed to unlock when power is lost, ensuring that individuals can exit a facility safely, which is particularly important in environments where life safety is a concern, such as in emergency situations. This design helps maintain safety by allowing free egress.

On the other hand, "fail secure" locks remain locked when power is lost, ensuring that unauthorized entry is prevented even during a power outage. This categorization is crucial in securing sensitive areas where maintaining security is a priority, even at the risk of hindering egress temporarily.

By understanding these two terms, professionals can choose the appropriate type of electrified lock based on the security requirements and safety considerations of a given location. The other options, while they might describe aspects of access control, do not provide the same level of relevance or operational implications for electrified locks as fail safe and fail secure do.
