• NKT12(1-1)BX
• XAA25302P5

These model references are useful for search coverage and quotation confirmation. However, the final replacement should still be confirmed by the old intercom label, panel installation position, connector type, wiring method, and elevator communication system.

Car Operating Panel Communication Use

NKT12(1-1)BX should be understood as a car-side intercom or COP communication component, not a display board, button board, or main control PCB.

In elevator operation, the car intercom is an important communication device. It may be used when passengers need to contact the duty room, monitoring center, building management, or rescue service during an elevator fault or emergency situation.

Because this part is related to elevator communication, it should be matched by the original system and wiring instead of only by the front appearance.

Model Number and Label Confirmation

For this product, buyers may provide different visible markings from the same old unit.

Some customers may search by NKT12(1-1)BX, while others may use XAA25302P5 or XO5249B212 from the old label, supplier document, or maintenance record. These numbers should be kept together on the page because they may refer to the same COP intercom product group.

Before ordering, please confirm:

• Complete NKT12(1-1)BX marking
• XAA25302P5 marking if visible
• XO5249B212 marking if visible
• Front photo of the intercom unit
• Back photo of the device
• Connector and wiring photo
• COP installation position
• Elevator brand or controller system if available
• Existing communication fault description

If the old label is unclear, a full photo of the car operating panel internal wiring can help confirm the correct replacement faster.

When Technicians Usually Check This Unit

Maintenance teams may inspect the COP intercom when the elevator has issues such as:

• no voice communication from the cabin
• emergency call not working
• intercom button has no response
• weak or unstable audio
• communication line abnormality
• damaged connector or wiring
• old intercom unit failure
• abnormal response from monitoring or duty room side

These symptoms may not always be caused by the intercom itself. The COP wiring, intercom power supply, communication cable, duty room host, emergency call button, connector terminals, and controller-side communication circuit should also be checked before confirming the device fault.

Practical Replacement Notes

Do not select NKT12(1-1)BX XAA25302P5 XO5249B212 only by appearance.

Elevator intercom devices may look similar, but the wiring definition, connector type, power requirement, communication mode, and system compatibility may be different. Before installation, technicians should compare the old and new unit carefully and test the communication function after replacement.

For overseas buyers, sending clear photos of the original intercom label, front side, back side, connector area, and COP installation position is the safest way to reduce wrong supply before shipment.

If the elevator uses an OTIS, Xizi OTIS, or related elevator communication system, please mention this during inquiry so the intercom model and wiring can be checked more accurately.
