Is it permitted by code to add a feature allowing a push button to lock electrically locked doors even during an alarm?

In fire alarm systems, the primary goal is to ensure the safety of occupants by facilitating their quick and safe evacuation during an emergency. Adding a feature that allows a push button to lock electrically locked doors during an alarm contradicts this objective and can pose significant safety risks.

According to the applicable codes and standards, such as the National Fire Protection Association (NFPA) codes, doors that are held in a locked position must be able to be overridden or unlocked in the event of a fire alarm. This ensures that all exits remain accessible for occupants to escape quickly without hindrance.

Locking doors during an alarm, even if a push button interface is available, can lead to dangerous situations where occupants may become trapped, thus violating safety protocols stipulated in fire codes. Therefore, implementing a feature that allows locking doors during an alarm is not permitted under standard codes, reinforcing that absolute safety and accessibility must take precedence in any design or feature consideration regarding fire alarm systems.

Understanding this context is crucial for ensuring compliance with fire safety regulations and protecting building occupants in emergency situations.
