Description

• Precise Obstacle Detection: Detects objects as small as 5mm (e.g., fingers, bags) within a 0.5-2.5m range, eliminating blind spots in the door path.

• Anti-Interference Performance: Equipped with a dual-frequency filter, it resists interference from sunlight, LED lights, and other elevator electrical components—reducing false triggers by 90% compared to generic sensors.

• Perfect Compatibility: Its mounting holes, wiring ports, and signal protocols align 100% with Otis door system specifications, requiring no modifications to existing door control units.

• Durability: The ABS housing resists impact (up to 5N) and corrosion, while the IR components maintain performance in temperatures ranging from -20°C to 60°C—ideal for elevators in cold or hot climates.

1. Pre-Installation Preparation:

• • Execute the Lockout-Tagout (LOTO) procedure: Shut down the elevator’s main power and disable the door control system to prevent accidental door movement.

• • Confirm compatibility: Use Nanjing Zhuye Elevator Parts’ free online tool (via their official website) to verify the JCA00629AAB002 matches your Otis elevator’s door model (e.g., Otis Gen2, 3300).

• • Gather tools: Phillips screwdriver, wire stripper, digital multimeter, and a level (for alignment).

2. Removal of Old Sensor:

• • Locate the old ADS-93 sensor (typically mounted on the top/bottom of the elevator door frame, labeled “JCA00629AAB002”).

• • Disconnect the wiring: The sensor has 3 wires (power: red, ground: black, signal: blue)—mark each wire with tape to avoid misconnection.

• • Remove the mounting screws (2-4 screws, depending on the door frame) and take out the old sensor.

3. Installation of New JCA00629AAB002 Sensor:

• • Clean the mounting surface with a dry cloth to remove dust or grease.

• • Align the new sensor with the door frame using a level (ensure the IR emitter/receiver is parallel to the opposite door edge) and secure it with the original screws (tighten to 3-5 N·m to avoid housing damage).

• • Reconnect the wires: Match red (power, 12V DC) to red, black (ground) to black, and blue (signal) to blue. Use the multimeter to confirm correct voltage (11.5-12.5V DC) before powering on.

4. Post-Installation Testing:

• • Restore power to the door control system and enter maintenance mode (follow Otis’s door system manual).

• • Perform obstacle tests:

• • • Hold a flat object (e.g., a book) in the door path— the sensor should trigger the door to reverse within 0.3 seconds.

• • • Test at 3 positions (top, middle, bottom of the door path) to ensure full coverage.

• • Check for false triggers: Shine a flashlight or LED light at the sensor— the door should continue closing normally (no false reversal).

• • If issues occur (e.g., no detection, frequent false triggers), recheck alignment or wiring, or contact Nanjing Zhuye Elevator Parts’ 24/7 technical support.

5. Daily Operation Tips:

• • Facility managers should instruct passengers not to block the sensor with stickers or objects—this can disable its safety function.

• • Schedule monthly visual checks: Ensure the sensor’s lens is clean (wipe with a soft cloth if dusty) and the wiring is not frayed.

• Normal Use (residential buildings, 8-12 hours daily operation, clean environment): Replacement cycle of 4 to 6 years.

• High-Intensity Use (commercial buildings, hospitals, 18-24 hours daily operation, frequent door cycles): Replacement cycle shortened to 2.5 to 3.5 years.

• Harsh Environments (elevators in factories, coastal areas with salt spray, or dusty locations): Replacement cycle of 1.5 to 2.5 years.

• Reduced detection range: The sensor fails to detect obstacles beyond 1m (test with a standard object).

• Frequent false triggers: The door reverses without obstacles in the path.

• No signal output: The multimeter shows 0V on the blue (signal) wire when an obstacle is present.

• Physical damage: Cracks in the housing, broken lens, or frayed wiring.

• Genuine Quality: Each sensor uses Otis-approved components (e.g., Sharp IR emitters) and comes with a 2.5-year warranty.

• Technical Support: Free video tutorials for installation/testing and a dedicated team to resolve compatibility issues.

• Fast Delivery: Global shipping takes 3-5 days for major markets (Europe, North America, Asia), minimizing elevator downtime.
