Elevator Car Intercom RFT12-B TK-T12(1-1)B – Nanjing Zhuye Elevatorparts

The elevator car intercom is a vital communication link for ensuring passenger safety and handling emergencies, serving as the “voice bridge” between the car, machine room, and monitoring center. The Elevator Car Intercom RFT12-B TK-T12(1-1)B provided by Nanjing Zhuye Elevatorparts is a high-reliability communication device tailored for modern elevator systems. It covers two compatible models (RFT12-B and TK-T12(1-1)B) to meet the matching needs of different elevator control systems and is widely compatible with mainstream brands such as Schindler, OTIS, and KONE. This intercom supports clear two-way communication, with anti-interference technology to ensure stable sound transmission even in complex electrical environments. Crafted with high-quality ABS shells, noise-canceling microphones, and high-fidelity speakers, it meets international elevator safety standards (EN 81-20, GB 7588) and has become a trusted choice for global elevator maintenance teams and property management companies.

Nanjing Zhuye Elevatorparts adheres to the core philosophy of “Clear Communication, Reliable Connection” and implements strict quality control throughout the production process of the RFT12-B TK-T12(1-1)B intercom. Each unit undergoes rigorous testing, including communication clarity verification, anti-interference performance testing, waterproof and dustproof detection, and mechanical life assessment. The intercom adopts digital signal processing technology to reduce background noise, with a signal transmission distance of up to 500 meters, ensuring clear communication between the car and the monitoring center. Its ABS shell has an IP54 protection rating, effectively resisting dust and moisture in the elevator car environment. The built-in high-capacity standby battery can support continuous work for 4 hours in case of power failure, ensuring emergency communication is not interrupted. The simple and durable operation panel is designed with large buttons, making it easy for passengers of all ages to use in emergencies.

Usage Guide for Elevator Car Intercom RFT12-B TK-T12(1-1)B

Correct installation, operation, and maintenance are crucial to ensuring the stable performance of the RFT12-B TK-T12(1-1)B elevator car intercom. Nanjing Zhuye Elevatorparts recommends that only certified elevator technicians perform installation and maintenance to avoid communication failures or safety hazards caused by misoperation.

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 and communication system match the RFT12-B TK-T12(1-1)B intercom (check parameters such as signal type, installation dimensions, and voltage). 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 intercom system, lock the switch, and place a “Maintenance in Progress” warning sign at the landing doors and machine room entrance. Locate the intercom installation position (usually on the car wall or control panel) and clean the area to remove dust and debris. Finally, prepare professional tools such as a screwdriver, wire stripper, multimeter, and cable tester, and check that the new intercom from Nanjing Zhuye Elevatorparts is intact (no damage to the shell, no loose wires).

2. Installation & Wiring

If replacing the old intercom, first take photos to record the wiring positions (power supply, signal lines) for later reference. Disconnect the wiring of the old intercom according to the labels and remove the old device. Take the new RFT12-B TK-T12(1-1)B intercom, fix it on the car wall or bracket with screws, and ensure it is installed firmly and at a height convenient for passengers to operate (1.2-1.5 meters from the car floor). Connect the wires strictly following the wiring diagram provided by Nanjing Zhuye Elevatorparts: connect the power supply line to the “POWER” terminal, and the signal line to the corresponding interface of the elevator’s communication main unit (note the positive and negative poles and signal direction). After wiring, use a screwdriver to tighten the terminals and use a cable tester to check the continuity of the signal line.

Debugg3. Operation & Daily Maintenance

Restore the power supply and test the intercom’s function: Press the call button on the car intercom, and confirm that it can quickly connect to the machine room or monitoring center. Check the communication clarity—both sides should hear clearly without noise or echo. Test the standby battery function by cutting off the main power supply, ensuring the intercom can still work normally. For daily maintenance, inspect the intercom during weekly car patrols: Check if the shell is damaged or loose; confirm the call button is sensitive and rebounds normally; check the wiring terminals for oxidation or looseness. Clean the intercom surface with a dry cloth regularly to remove dust. Every 3 months, test the communication function and battery performance; every 6 months, check the signal line connection and replace the standby battery if necessary (recommended to use Nanjing Zhuye’s original batteries for compatibility).

Replacement Cycle of Elevator Car Intercom RFT12-B TK-T12(1-1)B

The replacement cycle of the RFT12-B TK-T12(1-1)B intercom is closely related to operating environment and usage frequency. Under normal circumstances (elevator daily operation 12-24 hours, car environment dry and low-dust, no frequent emergency calls), Nanjing Zhuye Elevatorparts recommends a replacement cycle of 4-5 years. This cycle is determined based on long-term field data, component aging tests, and battery life assessments, fully considering the aging of internal electronic components, the attenuation of speaker/microphone performance, and the loss of standby battery capacity.

For elevators in harsh environments (e.g., high-humidity areas, coastal regions with high salt spray, or dusty industrial sites) or high-traffic areas (e.g., shopping malls, airports with frequent intercom use), the replacement cycle should be shortened to 2-3 years. Harsh environments accelerate the corrosion of the shell and terminals, while frequent use increases the wear of buttons and internal components. 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 5-6 years, but only after inspection and confirmation by Nanjing Zhuye’s technicians that the intercom’s communication clarity, battery performance, and signal stability meet safety standards.

Replace the intercom immediately if any of the following issues occur, regardless of its service life: The intercom fails to call or connect, or the communication is unclear and cannot be repaired; the standby battery cannot hold a charge, failing to work during power outages; the shell is severely damaged or corroded, with internal circuits exposed; the call button is stuck or ineffective; the intercom makes abnormal noise (e.g., static, squeaking) that affects communication, and the fault cannot be eliminated by debugging.
