According to Life Safety Code (NFPA 101), what must locks, latches, and alarm devices NOT require to open egress doors?

Locks, latches, and alarm devices on egress doors must be designed to ensure that occupants can exit safely and promptly during an emergency. According to the Life Safety Code (NFPA 101), it is critical that these doors can be opened without the need for special knowledge or effort. This requirement ensures that in emergency situations, individuals can quickly and effectively access exits without confusion or additional training.

If devices required special knowledge, it could lead to increased risk during emergencies, as individuals might not be able to operate them quickly or at all. This principle underpins the importance of designing egress systems that are intuitive and accessible to all users, regardless of their familiarity with the specific security measures in place.

The other options, such as needing assistance from professionals, requiring maintenance every six months, or needing special tools for unlocking, do not align with the requirements for egress systems meant for life safety. Egress systems must be straightforward and effective, promoting immediate exit without complications or delays.
