Elevator Braille Push Button BR36A(B): Dual-Light Indication for Safe & Inclusive Operation

Proper Usage Methods of Elevator Braille Push Button BR36A(B)

1. Installation & Commissioning

• First, cut off the elevator power supply and secure the work area to ensure safety. Thoroughly clean the button installation holes on the elevator operation panel (cab and landing), removing dust, oil stains, and debris to ensure a tight fit.
• Accurately insert the BR36A(B) into the installation hole, ensuring the Braille labels are correctly aligned with the corresponding floor numbers (horizontal and vertical alignment error ≤ 1mm). Fix the button firmly using matching screws from the back of the operation panel. The tightening torque must comply with elevator manufacturer’s technical requirements (typically 1.5–2.5 N·m) to avoid loose buttons or damage to the panel.
• Correct wiring connection: In accordance with the wiring diagram provided by Nanjing Zhuye Elevatorparts and the elevator control system guidelines, connect the button’s power wires (usually DC 12V/24V) and signal wires to the corresponding terminals of the elevator control board. Pay special attention to the positive and negative poles of the LED light wires to ensure the red and white lights work correctly—red light lights up when the call is registered, and white light remains on in standby mode. Ensure all connections are tight and reliable, and the wire insulation layer is intact to prevent short circuits.
• Post-installation commissioning: Restore the elevator power supply and test each BR36A(B) button. Press the button to check if the press force is within the standard range (2–5N) and if there is no stuck or loose phenomenon. Verify that the white standby light is on normally and the red registration light is bright and goes out automatically after the elevator arrives. Confirm that the Braille labels are clearly identifiable and match the floor numbers accurately to ensure accessibility for visually impaired passengers.

2. Daily Operation & Routine Inspection

• During daily patrols, observe the dual-light indication status of each button. Abnormal phenomena such as dim lights, non-illumination, wrong light color (e.g., red light on standby), or flickering indicate potential faults in the button or wiring.
• Test the button press sensitivity regularly: Press each button to check if it responds promptly (signal transmission delay ≤ 0.5 seconds) and if there is any stuck, loose, or unresponsive situation. For buttons with stuck issues, clean the gap between the button and the panel with a dry brush to remove dust or debris.
• Conduct weekly cleaning and visual inspection: Use a dry, lint-free microfiber cloth to gently wipe the button surface and Braille labels, removing dust and fingerprints. Avoid using water, alcohol, or corrosive cleaners that may damage the button shell or fade the Braille labels. Check the button shell for cracks, scratches, or discoloration, and ensure the Braille labels are not worn or blurred.

3. Regular Maintenance

• Every 3 months, conduct a comprehensive inspection of the button’s wiring connections (after cutting off the power supply). Check if the terminals are loose, oxidized, or damaged, and retighten loose terminals or clean oxidized contacts with a professional cleaner. Use a multimeter to detect the power supply voltage, ensuring it remains within the standard range (typically DC 12V ± 0.5V or 24V ± 1V) to avoid damage to the LED lights or internal circuits.
• Every 6 months, perform a full performance test: Verify the button’s press force, signal response speed, and dual-light indication effect. Replace the LED light sources if the lights are dim or flickering (replacement parts provided by Nanjing Zhuye Elevatorparts are recommended to ensure compatibility). Check the tightness of the button’s fixing screws and adjust if necessary.
• Annually, arrange professional maintenance with Nanjing Zhuye Elevatorparts’ technical team. Disassemble the buttons to inspect internal components (including contact pins, springs, and circuit boards), remove internal dust, and replace aging components (such as springs or capacitors) if necessary. This ensures the long-term stable operation of the buttons and maintains their performance at the factory standard.

Recommended Replacement Cycle of Elevator Braille Push Button BR36A(B)

1. Standard Replacement Cycle

2. Scenario-Based Cycle Adjustment

• Harsh Operating Environments: For elevators in high-humidity coastal regions, high-dust construction sites, high-temperature unventilated areas, or public facilities with extremely high passenger flow (e.g., subway stations, large hospitals), the replacement cycle should be shortened to 3–4 years. Harsh conditions accelerate the wear of contact pins, corrosion of internal circuits, fading of Braille labels, and burnout of LED lights, significantly reducing the button’s reliability and service life.
• Low-Frequency Use Scenarios: For elevators with low usage frequency (e.g., villa elevators, small office buildings with less than 3,000 monthly rides) and stable operating environments, the replacement cycle can be appropriately extended to 6–8 years—provided a professional inspection by Nanjing Zhuye Elevatorparts confirms that the button’s press sensitivity, dual-light indication, Braille label integrity, and structural stability are intact.

3. Immediate Replacement Conditions

• The button is stuck or unresponsive, and the fault cannot be resolved after cleaning or maintenance; the press force exceeds 5N, making it difficult for passengers to operate.
• The dual-light indication fails (e.g., no light, wrong light color, or persistent flickering), and the fault cannot be fixed after replacing the LED light or checking the wiring.
• The Braille labels are severely worn, blurred, or fall off, failing to meet accessibility requirements for visually impaired passengers.
• The button shell is cracked or deformed, posing potential safety hazards; internal circuits are corroded, leading to unstable signal transmission or short-circuit risks.
