LIFT COMMUNICATION · LIFT-SIDE CONNECTION
Wireless
2/4-wire extension
2局 configuration
Use 4G IoT wireless communication to reach the duty side. Match field wiring to the 2-wire/4-wire intercom system and confirm the 2局 configuration against this panel and site requirements.

Check field wiring and wireless communication separately
The photo labels 1局 and 2局 separately. Prepare intercom and wiring details by group rather than infer terminal counts from a shared series illustration.
Intercom connections
Check wiring system, terminals and power for each group in the 2局 configuration. Panel labels do not establish site compatibility.
Wireless communication
Check operator coverage, accounts and console communication at the installation point. Confirm the separate purpose of the panel network port.
INTERCOM SYSTEM · CONNECTIONS
From the lift
to the duty station.
Lift-side intercoms connect to the duty side through a wireless extension and 4G IoT communication. Confirm site coverage, account 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; operator coverage, account and duty-console configuration.
Original wiring references
Chinese-language originals. Open when needed.
The drawing contains lift intercoms, power, an extension and different duty consoles. It explains the system relationship; its pictured extension count does not replace this model’s configuration.
The shared introduction shows one terminal group at the top, unlike this two-group unit. Its 1–4局 annotation describes the series; this page retains the 2局 configuration.
