Arkel KK2X3057AW Landing Call & Indicator Unit (2x30mm White Dot-Matrix)

The Arkel KK2X3057AW is a compact and stylish landing operating panel (LOP) interface designed primarily for the ARL-500 elevator control system. It features a high-contrast 2×30 mm White Dot-Matrix LED display capable of showing 2-character floor designations (0-99, B1-B9) and direction arrows. This unit combines modern aesthetics with robust CANbus communication, making it an ideal solution for residential and mid-rise commercial buildings.

Technical Specifications: KK2X3057AW

Product Description

The Arkel KK2X3057AW is designed to provide essential elevator information in a compact footprint. Unlike larger 3-panel displays, this 2×30 mm version is optimized for buildings with floor counts between 10 and 99, where a 3rd digit is unnecessary. The dot-matrix technology allows for clear depiction of floor numbers and travel direction arrows (Up/Down).

Engineering and Installation: The unit is built on a professional green PCB, integrating the call buttons and display driver into a single board. It utilizes the CANbus protocol for data transmission, ensuring reliable communication with the ARL-500 control system. The board includes the X-CB1 connector for communication and power, and an 8-pin DIP switch for assigning the floor address (Door A or Door B) without needing a computer for basic setup.

User Experience: Visual clarity is enhanced by the bright White LEDs, which offer superior visibility compared to standard red displays. For accessibility, the unit includes an integrated gong that sounds upon car arrival. Technicians can adjust the gong volume using the on-board potentiometer to match the ambient noise level of the building hallway.

Frequently Asked Questions

Q1: What is the difference between KK2X3057AW and KK3X3057AW?

The KK2X model features a 2-character display (2x30mm), suitable for floor designations like “12” or “B1”. The KK3X model features a 3-character display (3x30mm), which is required for high-rise buildings with triple-digit floor numbers (e.g., “105”) or complex alphanumeric codes,.

Q2: Can this unit be used with the Arkel ARCODE system?

The KK series is natively designed for the ARL-500 system. For ARCODE systems, the equivalent hardware is typically labeled as the BC-D2XAW (BC series), although they share similar physical characteristics. Always verify the firmware compatibility with your specific controller.

Q3: How do I adjust the volume of the arrival gong?

There is a specific trimpot (potentiometer) located on the PCB. You can turn this dial with a small screwdriver to increase or decrease the volume of the buzzer/gong sound.

Q4: Does the display support scrolling text?

Yes. The dot-matrix technology allows the unit to scroll messages such as “Out of Service”, “Overload”, or “Fire” when triggered by the main controller, providing more information than a simple 7-segment display.
