Description

Technical Field

[0001] The utility model relates to the technical field of elevator safety, in particular to a safety alarm device for an elevator. Background Art

[0002] The elevator safety alarm device is an emergency alarm device inside the elevator. Its main function is to quickly send out an alarm when passengers or staff encounter an emergency, in order to obtain rescue and ensure life safety. When passengers or staff encounter danger or emergency in the elevator, they can send out an emergency signal through the safety alarm device to notify the elevator monitoring center or relevant personnel for timely rescue.
