Up to 2 door stations are supported simultaneously in the intercom system.
Up to 3 indoor stations are supported simultaneously in the intercom system.
Here take 3 wirings as example.
According to different transmission distances among door stations and indoor
stations, different RVV4 cable specifications are demanded.
Transmission Distance (TD)
RVV4 Cable Specification
TD ≤10 m
RVV4 * 0.2 mm ^2
10 m < TD ≤30 m
RVV4 * 0.5 mm ^2
30 m < TD ≤50 m
RVV4 * 0.75 mm ^2
50 m < TD ≤100 m
RVV4 * 1.5 mm ^2
On the rear panel of the indoor station,
four-wire interface A and four-wire
interface C compose a cascading group;
and four-wire interface B and four-wire
interface C compose a cascading group.
The communication between A and B/D
cannot be realized.
The communication between C and B/D
cannot be realized.
Do not connect the power wire of the four-core cable to the V pin (video wire) or A pin
(audio wire) of the four-wire interface.
