This article reports that certain building doors can have controls so that people outside the building cannot enter the locked door while people inside the building can exit. The equipment fits well where the exit door may be near public areas or where shoplifters could leave without visibly bypassing a cashier or security officer. Typically, delayed egress is not permitted in assembly occupancies such as stadiums. They must be connected to the building fire alarm system. There is a fail-safe feature in which the door unlocks when there is a loss of power or fire.
