What characterizes a delayed egress device?

A delayed egress device is specifically designed to allow for controlled exits from a facility while providing a safeguard for residents, particularly in settings such as Residential Care Facilities for the Elderly. The defining feature of a delayed egress device is the built-in time delay that is activated when someone attempts to open the door from the inside. This mechanism allows care staff to respond appropriately before the door fully opens, ensuring that residents who may be at risk, particularly those with cognitive impairments, do not wander off unsupervised.

This time delay serves not only as a measure for safety and security but also enables staff to check on the individual attempting to exit, ensuring their well-being. In contrast, other options do not align with the specific function of a delayed egress device: a fast-acting security system suggests immediate action rather than a controlled exit, a common entry door lock does not have any delay mechanism, and a fire alarm system serves an entirely different purpose related to safety rather than controlled egress. Therefore, the attributes of a delayed egress device situate it as a specialized component essential for managing resident safety while still allowing for necessary access.
