What is delayed egress hardware?

Delayed egress hardware prevents a door from being opened from the egress side, usually for a period of 15 seconds. This type of device is often used to prevent theft, while maintaining life safety. The system is most commonly comprised of an exit device incorporating delayed egress features, or an electromagnetic lock and power supply, one of which would contain delayed egress circuitry. When the device is actuated, the door remains locked on the egress side for 15 seconds, and then releases to allow egress.

Before specifying or supplying delayed egress hardware, you must verify that it is allowed to be used in the applicable occupancy classification, and be aware of the other code requirements that pertain to the use of this product. The requirements vary depending on whether you are referring to the International Building Code (IBC) or NFPA 101 – The Life Safety Code. There may be additional local requirements as well.

NFPA 101 allows the use of delayed egress hardware on all occupancy types (low or ordinary hazard), with some conditions that must be met if it is used.
