In my current column in USGlass Magazine, I addressed the requirements for delayed egress locks, which have become common in retail facilities. This hardware allows egress to be delayed for 15 seconds (or 30 seconds where approved by the AHJ), but the model codes include a long list of criteria for these doors. Can you answer this question:
What is required for code-compliant delayed egress hardware?
Which occupancies are allowed to have delayed egress locks, and how does this hardware function during a fire or other emergency? If you’re not sure of the mandates for delayed egress applications, check out the post on the USGlass website!

In Canada, we can use Delayed Egress Devices in any building as long as the total time from activation to release of the device in no more than 15 seconds. Some Areas will allow us to use the Nuisance delay of not more than 2 seconds, as long as the Total time to release the device does not exceed the 15 Second Maximum
We are getting more and more asks for these devices to be installed on the entrance doors for Schools and Daycare centers, as they provide controlled access and egress from buildings. Persons just cannot exit without someone letting them out or in.
The devices are also connected to the Fire Alarm Systems in these buildings, so if someone does activate the Device, the buildings Fire Alarm also goes off.
This is turning out to be a major deterrent for persons to skip out of school as only teachers and school staff have the ability to let persons out, except at scheduled times that the doors are silenced for Start of the day and end of the day requirements.
Thanks for the info, Jim!
