Which statement best describes emergency egress control in access systems?

• A. Access control locks remain engaged during fire alarm
• B. All door locks release during fire alarm signal
• C. Only exterior doors release during alarm
• D. Locks release only with manual override

Answer: (B)

Emergency egress control is about ensuring people can exit quickly and safely when an alarm sounds. In access systems, the locks are designed to unlock automatically in response to a fire or emergency alarm, so every door in the egress path becomes unlocked without needing someone to intervene. This fail-safe behavior prevents trapping occupants and aligns with life-safety requirements that demand immediate egress. Choosing that all door locks release during the alarm signal is the best description because it guarantees unobstructed exit for both occupants and responders. Options that keep locks engaged, release only exterior doors, or require manual override would introduce delays or create spaces where people could be trapped, which is incompatible with safe evacuation practices.
