Art.2301N Entrances exchanger for VX2300 digital systems
Fig. 1 Fig. 2
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
amplication (“L” = low, “M” = medium and “H” = high) to compensate for dierent 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 rst exchanger and then onto the apartments from the BUS output of the rst 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 rst exchanger to the AUX of the second BUS- with AUX- and BUS+ with AUX+)
AUX+
IN1 Door station input 1 (the signal may be amplied by the relative jumper – L=Low, M=Medium and H=High)
IN2 Door station input 2 (the signal may be amplied by the relative jumper – L=Low, M=Medium and H=High)
IN3 Door station input 3 (the signal may be amplied by the relative jumper – L=Low, M=Medium and H=High)
IN4 Door station input 4 (the signal may be amplied by the relative jumper – L=Low, M=Medium and H=High)
PS1 Power Supply input 1 (use Art.2321/P set to V2 voltage level)
PS2 Power Suppy input 2 (use Art.2321/P set to V2 voltage level)
