What is a "panic button" in access control?

A panic button in access control is specifically designed to enhance security and respond to emergencies. When activated, it sends an immediate alert to security personnel or systems, triggering an emergency lockdown or alarm. This function is crucial in situations such as a robbery or other threatening scenarios, allowing for a quick response to ensure the safety of individuals in a building.

The other options refer to different functions within an access control system. Tracking door status involves monitoring whether a door is locked or unlocked, while managing after-hours access pertains to controlling entry during non-business hours. Reprogramming access credentials is related to updating or managing user permissions, which does not directly relate to immediate emergency responses. The role of a panic button is distinct in its focus on urgent, safety-driven actions, making it a vital component of a comprehensive security strategy.
