Hoistway doors are provided with which feature to allow emergency access?

• A. Emergency unlocking device
• B. Magnetic lock
• C. Intercom system
• D. Hydraulic release

Answer: (A)

Emergency access to the hoistway is provided by an emergency unlocking device, a mechanism that lets authorized personnel bypass the normal door lock and open the shaft door during a rescue. This feature is essential because power may be out or the car may be stuck, and firefighters or responders need a reliable way to reach the hoistway interior. The device is typically a mechanical release or switch designed to be used with a special key or tool carried by responders, ensuring rapid, safe entry for rescue operations. The other options serve different roles: an intercom system handles communication with occupants, a magnetic lock is a standard powered lock that may not function during an emergency, and a hydraulic release is part of the door operator system, not an emergency access override.
