an Elevator Intercom and Safety Component Set, a specialized collection of hardware used for emergency communication and passenger safety within lift systems. These components facilitate seamless communication between critical points such as the elevator car, machine room, and a central monitoring station.
Key Components
- Intercom Telephone Handsets: Two handsets (typically for the machine room and monitoring station) provide two-way audio communication between passengers and technicians, ensuring a rapid response during malfunctions.
- Emergency Power Supply (RKP220/12D): A backup battery unit that provides a reliable 12V DC power source for the intercom and emergency lighting during a power outage.
- Wired Piezoelectric Buzzer Alarm: A compact, high-decibel sounder (up to 110–120dB) that triggers audible alerts when the alarm system is activated.
- Elevator Door Sensors (Light Curtains): A set of WECO infrared sensors designed to detect obstructions in the elevator doorway. These "light curtains" prevent accidents by reversing the door if a person or object is detected.
- Shaft Limit Switches: Cylindrical proximity sensors (bottom right) used to monitor the car's position in the shaft and ensure it stops safely at the correct floor levels.
