How long will an egress door remain open when a REX button is pressed?

• A. 10 seconds
• B. 20 seconds
• C. 30 seconds
• D. 40 seconds

Answer: (C)

When a REX (Request to Exit) button is pressed, the egress door typically remains open for a duration of 30 seconds. This is a standard time frame used in many electronic access control systems to provide a safe and efficient exit path without creating security vulnerabilities. The purpose of this functionality is to ensure that individuals have adequate time to exit through the door while still maintaining the security protocols of the facility. A 30-second duration strikes a balance by allowing enough time for people to pass through while helping to prevent unauthorized access. Understanding this timing is crucial for designing and implementing effective egress systems in compliance with safety regulations. The other durations provided are either shorter or longer than the standard time, which may not align with safety best practices or the typical operating procedures established in most electronic access control systems.
