Delayed Egress Access Control Tutorial

By: Brian Rhodes, Published on Oct 04, 2017

Is it ever legal to lock people into a building?

The answer is: Yes... under specific situations.

With so much of access control driven by life safety codes, and a predominant focus of 'free egress' during an emergency, 'delayed egress' may run counter to common sense.

In this note, we explain the code, share real world applications and installation issues.

The sections inside cover:

  • The Major Codes Allowing Delayed Egress 
  • But Some AHJs Forbid Regardless
  • All Applications Specifically Limited By Code
  • Fire Alarm Override Required
  • Nuisance Delay Optional
  • Real-World Delayed Egress Applications
  • How It Is Implemented - Panic Bars, Access Control Systems and 'Exit Check' devices

I understand the battle of the code(s). I also understand the concerns of the customer. However 15 or 30 seconds delay is too long. Egress is Egress, delayed is dumb enforcement. If you are going to monitor a doorway that has a security concern there are other technologies to invest in that will capture, journal and report as needed.

30 seconds can mean your life.

You coworker goes insane and chases you with a gun...and when you reach the time delayed door.

You DIE.

30 seconds can be a lifetime when you are fleeing. 

This application has just never had any real publicity of a real world event where the 30 second delay meant DEATH.

So...speculate all you want, when it happens 15 or 30 second local AHJ dumbsh!ts will be challenged.

-Overruled

 

 

 

Good report!  These devices can be a challenge to use, it is important to involve the AHJ during the planning stage.

If no delay is allowed by code, then 'pranking' the door by bumping the bar and running is a potential irritant...

Are 'bump and run' pranksters really deterred by a three second delay?

Sure, if it's not obvious that bumping the bar sounds an alarm, then they just go find something else to mess with.

...then they just go find something else to mess with.

Yeah, you're right, kids today have no patience. Now back when we were pranksters...
