LIFT COMMUNICATION · LIFT-SIDE CONNECTION
IP multi-port
2/4-wire extension
2-group configuration
Connect to the duty side over the project IP network. This configuration has two intercom terminal groups in its product photo. Match wiring, intercom system and installation conditions to the actual unit.

Check intercom groups and communication separately
Check the two intercom groups against their terminals and the three network-port roles against the project plan. These are separate sets of connections.
Intercom groups
Here, 2局 identifies the configuration with two intercom terminal groups. Check the intercoms, L/R/G/12V markings and 2-wire/4-wire version for each group.
Project network
Confirm access points, addressing and console communication. Distinguish visible interfaces from the functions available in the actual configuration.
INTERCOM SYSTEM · CONNECTIONS
From the lift
to the duty station.
Lift-side intercoms connect to the duty side through an extension and the project IP network. Match the existing intercoms, network access and console configuration.

The four locations are intercom positions; this model has 2 intercom terminal groups. Location count and terminal-group count describe different things. The AI-generated scene is conceptual, not a product image or a terminal or installation wiring drawing.
Three checks before connection
Existing intercom model and wiring system; the terminal groups, supply and actual wiring; project network and duty-console configuration.
Original wiring references
Chinese-language originals. Open when needed.
The image includes intercoms, power, an extension and different duty consoles. It explains the system relationship; confirm group counts and interfaces against this actual model.
The shared IP introduction starts with a single-port, one-group extension. This model’s lead photo has three network ports and two intercom groups; check wiring against its actual panel. The two-party drawing’s “4G one-key dialling extension” label does not establish built-in 4G on this IP model.
