What does the term "elevator recall" refer to during an emergency?

The term "elevator recall" refers specifically to the process where elevators are returned to designated floors automatically during an emergency, particularly a fire. In the event of a fire alarm or other emergency situations, the elevator system is designed to recall all elevators to a pre-determined or designated floor, typically the ground floor or an exit level. This functionality is crucial for safety, as it prevents elevators from serving floors above the fire or emergency location, thereby protecting occupants from inadvertently entering an unsafe area and allowing emergency responders easier access.

The automatic recall of elevators helps ensure that they are not used by occupants trying to escape from the building, as elevators can become hazardous during a fire due to smoke and potential entrapment. This built-in safety feature plays a vital role in the overall emergency evacuation plan, ensuring a smoother and safer evacuation process.
