B3IN

[bhtedu]

Hello, I have a question.

Can connect multiple b3IN in series, using the "I" port?

I have installed 2 or 3 sensors in each B3IN and have problems:

1: Two outdoor pir sensors (12mA)
No work both at once. separated works.
2: 1 water sensor, 1 gas sensor.
No work both at once. separated works.

I tried to connect a B3IN to another through the "I" port, and one sensor in each b3in. But neither works...

Hello and welcome...

1: Two outdoor pir sensors (12mA)

12+12=24mA - maximum on B3IN is 25mA ... is almost too much. Try an external power suply. But remember the input contact must be potential free.

Can connect multiple b3IN in series, using the "I" port?

u can only use one B3IN on one LCN-Module.

greetings Carsten

Hi and welcome

See also jumper settings in B3IN Instructions (maybe not easy if you got the paper in german)

Jumper setting active low (jumper on the left):
When an input against the GND terminal is bridged, the connected module sends the MAKE command.
On opening, comes the BRAKE command.

Jumper setting active high (jumper right):
When the voltage is bridged to an input for the supply voltage, the BRAKE command is sent.
In an open contact input the MAKE command is executed

It must be the same for all contacts, mixed connections are not possible.

Good luck, Uwe
