Communication System: It facilitates communication with passengers during emergencies or provides announcements and instructions if needed.

In summary, A lift or elevator system consists of several key components that work together to provide vertical transportation within a building. The main control system manages all operations, while the motor driver supplies electrical energy and controls the motor. A power supply system provides power to various components, and the hoist machine raises and lowers the lift car. Safety systems ensure passenger safety, call buttons enable users to request stops, and display indicators show the lift's position. Landing doors allow access to the lift car, and a communication system facilitates emergency communication and announcements. Understanding these components is crucial for comprehending the functionality and safe operation of a lift or elevator system.
