Final answer:

Step-by-step explanation:
The locked doors in secure units must immediately disengage when a fire alarm is activated. This security measure is crucial as it helps to prevent potential for extreme physical danger during emergencies such as fires where there is uncertainty over whether a serious fire or hazard awaits after an alarm. It ensures that all occupants can exit the building safely and quickly, overcoming any challenge that locked doors would present in an evacuation scenario.
Locked doors in secure units must immediately disengage when:
A fire alarm is activated
A resident requests to leave
The purpose of this is to ensure the safety and well-being of the residents in case of emergencies. When a fire alarm is activated, it is crucial that the doors disengage to allow for a quick evacuation. Similarly, if a resident needs to leave urgently, the doors should also disengage to grant them timely access.
