Delayed Egress Access Control Tutorial

By Brian Rhodes, Published Feb 04, 2020, 10:39am EST (Info+)

Delayed Egress marks one of the few times locking people into a building is legal.

With so much of access control driven by life safety codes, and a predominant focus of 'free egress' during an emergency, 'delayed egress' is contrary in preventing immediate exit.

If someone attempts to crash through an opening, an alarm sounds for 15 - 30 seconds before unlatching, allowing for store associates to apprehend the shoplifter before escape is possible.

unless they pull the fire alarm...

This is true! As noted in the post:

Fire Alarm Override

Another requirement: even if delayed egress is used, all doors must be made to unlock immediately when the fire alarm is pulled.

2015 NFPA 7.2.1.6.1 (1) specifies that they must release if any of the following activate:
(a) The automatic sprinkler system
(b) Not more than one heat detector
(c) Not more than two smoke detectors

Doesn't mention anything about manual pull stations, which is in line with 7.2.6.2 3 (c) discussing Access-Controlled Egress Doors

"The activation of manual fire alarm boxes that activate the building fire-protective signaling system specified in 7.2.1.6.2 (4) shall not be required to unlock the door leaves"

2015 ICB 1010.1.9.7 on delayed egress states:

1. The door locks shall unlock on actuation of the automatic sprinkler system or automatic fire detection system, allowing immediate, free egress.

So I guess it's whether the AHJ wants to allow the pull stations to be exempt from releasing the delayed egress...

An insightful article, never thought of the benefits of delayed egress access control.

We use delayed egress in various situations. At one of our buildings we needed to provide a pathway through a pair of double doors, but we wanted to control access to both doors. We ended up putting a card reader and electric strike on one leaf and then putting on a delayed egress bar (Chexit) on the other leaf. That way we could still control access to that area of the building and ensure that we were code compliant for egress purposes.
