DESCRITPION
This unit is required for systems with 2 or more entrances (4 maximum). The Art. 2301N has 4 inputs (IN1..IN4) each with adjustable
amplification (“L” = low, “M” = medium and “H” = high) to compensate for different door station distances. The AUX input enables
a second Art. 2301N device to be connected to expand the system up to 8 entrances. When connecting 2xArt. 2301N the polarity
of the bus between the Art. 2301N’s must be observed. When connecting 2xArt. 2301N’s the BUS output of the second exchanger
must be linked to the AUX input of the first exchanger and then onto the apartments from the BUS output of the first exchanger.
The polarities are not relevant if there is only one Art. 2301N.
The power supply inputs are PS1and PS2. The Art. 2321/P with its jumper set to V2 should be used. For systems with up to 4 entran-
ces and 50 video- phones only one power supply is required connected to PS1. For larger systems connect a power supply to each
of the two inputs (PS1 & PS2).
When 2xArt. 2301N, the 2xArt. 2321/P power supplies only connect to the Art. 2301N at which the AUX connection is used.
(The one supplying the apartments).
CONNECTION TERMINALS AND JUMPERS
BUS
–
BUS Output (observe the polarities only when linked to the AUX input of a second Art. 2301N)
BUS+
AUX
–
Auxiliary BUS input to carry out systems up to 8 entrances linking together two Art. 2301N (observe the polarities when
connecting the BUS output of the first exchanger to the AUX of the second BUS- with AUX- and BUS+ with AUX+)
AUX+
IN1
