Elevator Car Top Walkie-Talkie Lighting 12V TK-EP220/12H-10-Li: Dual-Function Safety Core from Nanjing Zhuye Elevatorparts

Step-by-Step Usage Guide for 12V TK-EP220/12H-10-Li Elevator Car Top Walkie-Talkie Lighting

1. Professional Installation & Wiring

• Safety Preparation: Cut off the elevator’s main power supply and fix the elevator car to a safe position using a safety clamp. Clean the car top mounting area (usually near the maintenance panel) to remove dust, oil stains, and debris that may affect installation stability.
• Component Installation: Fix the TK-EP220/12H-10-Li to the car top dedicated mounting bracket using high-strength stainless steel screws provided by Nanjing Zhuye Elevatorparts. Ensure the lighting head is adjustable (covers the entire car top working area) and the walkie-talkie antenna is installed vertically to enhance signal reception. Connect the component’s power terminal to the car top 12V DC dedicated power supply (ensure correct polarity to avoid damaging the lithium battery) and the communication terminal to the elevator intercom system bus according to the wiring diagram.
• Post-Installation Debugging: Restore the power supply and switch the elevator to inspection mode. Test the lighting function: turn on the lighting switch to check if the LED light is bright and stable, and adjust the lighting angle to cover key working areas (e.g., traction machine, safety components). Test the walkie-talkie function: communicate with the control room and car interior intercom to verify clear voice transmission (no noise or signal interruption). Check the battery charging function: connect the charger to confirm the charging indicator works normally (red light when charging, green light when fully charged).

2. Daily Operation & Routine Inspection

• Pre-Operation Check: Before starting car top maintenance, turn on the TK-EP220/12H-10-Li to check the lighting brightness (no dimming) and walkie-talkie signal (clear communication with the control room). Check the battery level indicator—ensure the battery is sufficiently charged (≥ 70%) to avoid sudden power failure during work. If the battery level is low, charge it immediately using the dedicated charger provided by Nanjing Zhuye Elevatorparts.
• Daily Visual Inspection: After maintenance, check the external condition of the component. Ensure the aluminum alloy shell is free of cracks, deformation, or corrosion; the LED lighting surface is clean (no dust accumulation affecting brightness); the antenna is intact and tightly connected; the wiring terminals are tight without looseness, oxidation, or burning marks.
• Weekly Functional Check: Conduct a comprehensive test of the lighting and walkie-talkie functions. Verify the lighting’s continuous working time (should not be less than 6 hours when fully charged) and the walkie-talkie’s communication range (stable within 300m in complex shaft environments). Check the charger’s performance—ensure it can fully charge the battery within the specified time (usually 2–3 hours).

3. Regular Maintenance Schedule

• Monthly Maintenance: Turn off the power supply and disconnect the wiring. Clean the shell, LED lighting surface, and antenna with a dry, lint-free cloth or a professional cleaner (avoid using corrosive agents). Inspect the wiring for aging or cracking (replace with genuine cables if necessary) and recheck all connections for tightness. Charge the battery fully even if it is not fully discharged to maintain battery performance.
• Quarterly Performance Test: Conduct a comprehensive performance test, including lighting brightness (using a lux meter to verify it meets the standard ≥ 500lux at 1m distance), walkie-talkie signal strength (signal-to-noise ratio ≥ 40dB), and battery capacity (capacity attenuation ≤ 10% of the original capacity). For elevators in harsh environments (high humidity, heavy dust), increase the test frequency to once every 2 months.
• Semi-Annual Professional Overhaul: Arrange a professional inspection with Nanjing Zhuye Elevatorparts’ certified technical team. Disassemble the component to inspect the internal circuit board, battery, and LED module for aging or damage. Replace aging parts (e.g., battery, LED bulbs) with genuine components. Re-calibrate the walkie-talkie signal to ensure compatibility with the elevator intercom system.

Recommended Replacement Cycle for 12V TK-EP220/12H-10-Li Car Top Walkie-Talkie Lighting

1. Standard Replacement Cycle

2. Adjustments for Special Scenarios

• Harsh Environments: For elevators in high-humidity coastal areas (salt spray corrosion), high-dust construction sites, or shafts with large temperature fluctuations (e.g., unheated industrial buildings), the replacement cycle should be shortened to 2–3 years. Harsh conditions accelerate shell corrosion, battery capacity attenuation, and internal circuit aging, significantly reducing the component’s reliability.
• Low-Frequency Use Scenarios: For elevators with low maintenance frequency (e.g., villa elevators, small office buildings with annual maintenance ≤ 12 times) and clean, stable car top environments, the replacement cycle can be extended to 4–5 years—only if Nanjing Zhuye’s professional inspection confirms the component’s lighting brightness, communication stability, and battery capacity are intact (meet the original factory performance requirements).

3. Immediate Replacement Conditions

• The LED lighting brightness drops by more than 30% (even after cleaning) or has obvious dark spots, failing to provide sufficient illumination for maintenance work.
• The walkie-talkie has frequent signal interruption, heavy noise, or no communication function, and the fault cannot be eliminated through debugging (e.g., antenna adjustment, wiring check).
• The lithium battery has severe capacity attenuation (continuous working time ≤ 2 hours when fully charged) or cannot be charged normally, affecting normal use.
• The component’s shell is severely cracked, deformed, or corroded; internal components show signs of burning (e.g., marks, odor), and the component cannot work normally even after maintenance, posing safety hazards.
