The intercoms feature noise-canceling technology that filters out background noise from the elevator operation, ensuring clear voice transmission even in noisy environments. The anti-interference circuit modules effectively resist electrical interference from the elevator’s internal system, including the door machine pulley drive system. They can work stably in a voltage range of 12V-24V and a temperature range of -20℃ to 60℃, with an IP54 dustproof and waterproof rating, adapting to the complex operating environment of elevator cars.

Usage Guide for Elevator Car Intercom TJ-2Y/TJ-2A/KON12B

Correct installation, debugging, and use of the TJ-2Y, TJ-2A, and KON12B car intercoms are crucial to ensuring emergency communication and coordinated maintenance of the door machine pulley system. Nanjing Zhuye Elevatorparts emphasizes that only certified elevator maintenance technicians are allowed to perform installation and replacement operations.

1. Pre-Installation Preparation

First, confirm that the elevator’s MAC car lighting controller model matches the POWCV24181MH power supply (check parameters such as input voltage, output voltage, output current, and installation dimensions). Consult Nanjing Zhuye Elevatorparts’ technical team if there is any uncertainty about compatibility. Then, cut off the elevator’s main power supply and the secondary power supply for the car lighting system, lock the switch, and place a “Maintenance in Progress” warning sign at the elevator landing doors and machine room entrance. Locate the power supply installation position (usually on the car top or in the car control cabinet) and clean the area to remove dust, debris, and oil stains. Finally, prepare professional tools such as a screwdriver, wire stripper, multimeter, and insulation tester, and check that the new POWCV24181MH power supply from Nanjing Zhuye Elevatorparts is intact (no damage to the shell, no loose pins).

First, confirm that the elevator model matches the selected intercom model (TJ-2Y/TJ-2A/KON12B) by checking parameters such as voltage, interface type, and installation dimensions. Consult Nanjing Zhuye Elevatorparts’ technical team if there is any uncertainty about compatibility. Then, cut off the elevator’s main power supply and control system power supply, lock the switch, and place a “Maintenance in Progress” warning sign at the elevator entrance. Remove the car ceiling or intercom installation panel to expose the internal installation position. Finally, prepare professional tools such as a screwdriver, wrench, multimeter, and wire stripper; clean the installation area, and check the door machine’s drive and driven pulleys for normal operation (record any abnormalities to communicate via the intercom during subsequent maintenance).

2. Installation & Wiring

If replacing an old intercom, first take photos to record its installation position, wiring connections, and fixing method for later reference. Disconnect the wiring harness from the old intercom according to the recorded labels and remove the old intercom. Take the new intercom (TJ-2Y/TJ-2A/KON12B) from Nanjing Zhuye Elevatorparts, install it on the preset bracket, and fasten it firmly with screws. Ensure the intercom’s microphone and speaker are not blocked. Connect the wiring harness to the corresponding terminals strictly following the photos and the wiring diagram provided by Nanjing Zhuye—distinguish between power wires, signal wires, and ground wires to avoid wrong connection. After wiring, use a multimeter to test the power supply voltage to confirm it matches the intercom’s rated voltage (12V-24V).

3. Usage & Daily Maintenance

Restore the power supply and install the car ceiling or intercom panel back. Test the intercom: Press the emergency call button in the car, and it should quickly connect to the machine room or monitoring center with clear two-way communication. During maintenance, use the intercom to communicate with the machine room to coordinate the operation of the door machine pulley system (e.g., instructing to start/stop the door machine for pulley inspection). For daily maintenance, inspect the intercom during weekly elevator patrols: Check if the call button is sensitive, the display light is normal, and the speaker/microphone work properly; clean the intercom surface with a soft dry cloth. Every 3 months, recheck the wiring connections to avoid loose contacts; every 6 months, test the communication quality and adjust the volume if necessary. At the same time, check the door machine pulley system’s operation—report any abnormalities via the intercom to the maintenance center promptly.

Replacement Cycle of Elevator Car Intercom TJ-2Y/TJ-2A/KON12B

The replacement cycle of the TJ-2Y, TJ-2A, and KON12B car intercoms is closely related to operating conditions and the frequency of door machine maintenance (linked to pulley operation). Under normal circumstances (elevator daily operation 12-24 hours, car environment dry and clean, no frequent impact), Nanjing Zhuye Elevatorparts recommends a replacement cycle of 3-5 years. This cycle is determined based on long-term field operation data and component aging tests, fully considering the wear of buttons, attenuation of speaker/microphone performance, and aging of internal circuits.

For elevators in high-traffic areas (e.g., large shopping malls, airports with daily passenger flow exceeding 10,000) or harsh environments (car with high humidity, heavy dust, frequent vibration), the replacement cycle should be shortened to 1.5-2 years. High-frequency button operations accelerate button wear, while harsh environments cause component corrosion and affect communication quality. For low-usage elevators (e.g., villa elevators, small office buildings with daily operation time < 8 hours) in stable environments, the cycle can be extended to 5-7 years, but only after inspection and confirmation by Nanjing Zhuye’s technicians that the intercom’s communication performance and stability meet standards.

Replace the intercom immediately if any of the following issues occur, regardless of its service life: The call button is stuck, insensitive, or invalid, failing to initiate calls; the speaker has no sound or distorted sound, or the microphone cannot transmit voice clearly; the intercom cannot connect to the machine room/monitoring center or frequently disconnects; the shell is severely damaged or corroded, losing protective performance; the intercom malfunctions and cannot coordinate with the door machine pulley system maintenance work normally.
