Mitsubishi Elevator Voice Announcement Board KCZ-921C KCZ-927D

Mitsubishi Elevator Voice Announcement Board KCZ-921C / KCZ-927D is used in Mitsubishi elevator voice announcement, voice broadcast, and cabin audio prompt applications.

This board is usually related to the elevator voice system, where floor arrival announcements, direction prompts, door operation messages, or service-related audio signals may be played depending on the elevator configuration.

In the elevator spare parts market, this product may also be searched as:

• Mitsubishi Elevator Voice Announcement Board
• Mitsubishi Elevator Voice Broadcast Board
• Mitsubishi Voice Station PCB Board
• Mitsubishi Elevator Audio Prompt Board
• Mitsubishi Elevator Voice Device Board
• Mitsubishi Elevator PCB Board

The main model references for this page are:

• KCZ-921C
• KCZ-927D

Related voice board references may include:

• KCZ-921D
• KCZ-925D
• KCZ-928D
• KCZ-929D
• OMZ-G2MS-01

These references are useful for search coverage and quotation confirmation. However, KCZ-921C, KCZ-921D, and KCZ-927D should not be treated as automatically interchangeable without checking the original board label, connector layout, voice system configuration, and installed elevator model.

Where This Voice Board Works

This board is normally connected with the elevator voice announcement system rather than the display or button circuit.

Depending on the elevator configuration, it may work with:

• cabin speaker
• voice announcement device
• floor arrival signal
• direction announcement signal
• door opening or closing prompt
• elevator controller audio output
• cabin wiring and speaker cable

If the elevator has no voice announcement, distorted audio, missing floor prompt, or abnormal broadcast behavior, technicians may inspect this board together with the speaker, wiring, power supply, and controller signal.

KCZ-921C and KCZ-927D: Check the Suffix Carefully

For Mitsubishi voice announcement boards, the suffix is important.

A buyer may search for KCZ-927D because it is visible on the old board. Another technician may report KCZ-921C from a cabinet label or maintenance record. Similar KCZ numbers may belong to the same voice announcement board family, but the board version, stored voice content, connector arrangement, or system application may be different.

If the old board label shows KCZ-921C, please use KCZ-921C as the main confirmation reference. If the old board shows KCZ-927D, do not replace it only by choosing another KCZ model with a similar number.

Audio System Details to Confirm

Before ordering Mitsubishi Elevator Voice Announcement Board KCZ-921C / KCZ-927D, please confirm:

• complete model number on the original board
• whether the old board shows KCZ-921C, KCZ-927D, or another KCZ version
• front and back photos of the PCB
• connector quantity and direction
• cabin or control cabinet installation position
• speaker wiring photo if available
• voice announcement language requirement if known
• whether OMZ-G2MS-01 appears on the old board or document
• existing voice fault description from the maintenance technician

This information helps confirm whether the required part is KCZ-921C, KCZ-927D, or another Mitsubishi elevator voice announcement board version.

Field Notes Before Replacement

Do not select this board only by appearance.

Voice announcement boards may look similar to other elevator PCBs, but their function, stored voice content, connector definition, and signal connection may be different.

If the elevator voice is silent, unclear, delayed, or missing some announcements, the problem may not always be the voice board itself. The speaker, audio cable, power supply, cabinet wiring, connector terminals, and controller output signal should also be checked before confirming the PCB fault.

For overseas buyers, sending clear photos of the old KCZ-921C / KCZ-927D board, connector area, speaker wiring, and installation position is the safest way to reduce wrong supply before shipment.
