Descripción
ZDH01-022-GG is a dedicated in-car communication device intercom system (with a built-in speaker and audio pickup module). It is a core safety component for elevator emergency communication and maintenance calls, compatible with all mainstream Mitsubishi elevator models.
ZDH01-022-GG is the car-side secondary unit of the Mitsubishi ZDH-E series elevator five-party intercom system, with two core functions:
- Emergency Rescue Communication: In the event of an emergency such as elevator entrapment, passengers in the car can use this device to achieve full-duplex two-way communication with the machine room, monitoring control room, car top, and pit. It is a key component of the elevator emergency safety system.
- Maintenance Operation Communication: During routine elevator inspection and maintenance operations, it enables real-time two-way communication between the car and locations such as the machine room, car top, and pit, improving the efficiency and safety of maintenance work.
Supporting Equipment of the Same Series: This device must be used with other components of the ZDH-E series five-party intercom system. The complete system includes:
ZDH01-020-GG: Local master station for the monitoring control room
ZDH01-021-GG: Machine room communication unit (core for system power supply and signal relay)
ZDH01-023-GG: Car top communication unit
ZDH01-024-GG: Pit communication unit
Applicable Elevator Types: Full range of Mitsubishi elevators, including passenger elevators, freight elevators, hospital elevators, and automobile elevators, as a factory-specified original supporting component.
