transmission distance).
Connector wire standard: double
–end 568B standard.
Panel electrical parameters
standby work current Less than or equal to 60 mA
Maximum work current Intercom/receive broadcast :less than or equal to 400 mA
standby voltage range More than 11V or less than 12V
working voltage range
Intercom/the max voltage of receive broadcast :more than
8V less than 12V.
Note: The more panels, the current will be bigger, the line pressure drop will be larger, the panel voltage will be
lower;
Also, the longer cable, the line impedance will be bigger, the line pressure drop will be larger, the panel voltage
will be lower.
Connection type
IP network intercom terminal and intercom panel are connected by standard 568B network cable by hand in hand, please
keep away from other interference lines within wiring. eg:220V or 380V power line, high power motor power line, frequency
equipment power line and control line ,etc.
If use suggested cable or better cable according to the standard 568B wire, we suggest as follows:

Terms explain
Panels numbers: IP network intercom terminal connected panel numbers.
Power position 1: the distance from IP network intercom terminal to the first external power source.
Power position 2: the distance from IP network intercom terminal to the second external power source.
Power position 3: the distance from IP network intercom terminal to the third external power source.
The total wire length: the maximum connections wire length from IP network intercom terminal to the end panel.

：
It means no this parameter.
Note: The panel numbers shouldn`t be more than 4 piece between the next two power supply, if over 4 piece, it
need increase the external power supply appropriately when it`s more than 4 piece panel.
Suggest the cable wire diameter is 0.5mm more 8 core copper twisted pair, when use the other type cable, the
communication distance will have a certain deviation.
When the panels ` number more than 4 pieces, it suggest to use the splitter to increase the panels` number and connect
