These references are useful for search coverage and quotation confirmation. However, different G versions should not be treated as automatically interchangeable without checking the original board label, connector layout, elevator system configuration, and fire-fighting operation circuit.

Fire-Fighting Z1 Board Application

This board should be understood as a fire-fighting related elevator PCB, not a normal display board, button board, or general interface board.

Depending on the elevator system, it may be connected with:

• fire service operation signal
• fireman control function
• emergency recall input
• fire-fighting switch circuit
• control cabinet signal interface
• emergency operation logic
• related controller input and output wiring

Because fire-fighting elevator functions are safety-related, replacement should be handled carefully by qualified elevator maintenance personnel. The old board model, cabinet wiring, and fire service operation setting should be confirmed before installation.

Model Confirmation Notes

Before ordering Mitsubishi Elevator Fire-Fighting Z1 Board P203795B000G01 / P203714B000G03, please confirm:

• complete model number on the original board
• whether the old board shows P203795B000G01 or P203714B000G03
• whether G04, G11, G12, or P203795B000G11 appears on the board or system document
• front and back photos of the PCB
• connector quantity and direction
• control cabinet installation position
• fire-fighting switch or fire service circuit information if available
• original fault description from the maintenance technician

If the old label is unclear, a full control cabinet photo and close-up photos of the PCB marking can help confirm the correct replacement faster.

Practical Replacement Notes

Do not select this board only by appearance.

Mitsubishi elevator fire-fighting boards may look similar to other control cabinet PCBs, but their signal definition, software logic, connector layout, and fire service function may be different.

If the elevator has fire service abnormality, emergency recall fault, fireman operation signal failure, or control cabinet fire-related error, the fault may not always come from the board itself. Technicians should also check the fire switch, wiring terminals, controller input signal, power supply, connector oxidation, and related safety circuit.

If the original board was damaged by wiring short circuit, unstable cabinet power, water damage, or external fire alarm interface problems, replacing only the PCB may not fully solve the issue.

For overseas buyers, sending clear photos of the old P203795B000G01 / P203714B000G03 board from both front and back sides is the safest way to confirm the correct replacement before shipment.
