Communication Relay: Serving as the signal hub within the hoistway, it receives signals from hoistway sensors (such as leveling, limit switches, and safety switches), the car, and hall call buttons. It communicates bidirectionally with the main control board (such as LCECPU) via a serial bus (such as TTS/LCE bus) to achieve signal transmission.

Audio-Visual Alarm Drive: It has a built-in alarm drive circuit. When the elevator triggers a fault (such as a safety circuit disconnection, door zone abnormality, or overspeed), it receives instructions from the main control board to drive the buzzer to sound and the warning light to flash, providing an audible and visual alarm within the hoistway.

Status Feedback: The system provides real-time feedback on the operating status and alarm signals of the hoistway equipment to the main control system. Based on this feedback, the main control system determines whether the elevator meets operating conditions, ensuring safety.

Core Function: It establishes a signal link between the hoistway and the control cabinet, serving as a crucial communication node for elevator safety monitoring, fault alarms, and stable operation.
