Which exit devices may be legally installed on fire doors?

1. Panic Exit Hardware

2. Fire Exit Hardware

3. Standard Exit Devices

4. Secure Lock Systems

The correct answer is: Fire Exit Hardware

Fire exit hardware is specifically designed to be installed on fire doors, meeting the stringent requirements of fire safety codes. These devices are constructed to not only allow for quick egress but also to maintain the fire-resistance rating of the door and frame. This is crucial because a fire door's primary function is to prevent the spread of fire and smoke, and improper installation or equipment that doesn't meet code can compromise this function. Panic exit hardware is designed for high-traffic areas and must be able to open easily under panic conditions, but it is not specifically tailored for fire-rated doors. Standard exit devices also do not inherently meet the requirements for use on fire doors. Secure lock systems typically focus on security rather than emergency egress and fire safety, making them inappropriate for installation on fire-rated doors. Therefore, only fire exit hardware is authorized for use on fire doors, ensuring compliance with safety regulations while providing necessary exit functions.
