Art.2301N
Entrances exchanger for VX2300 digital systems
Fig.1 Fig.2
DESCRIPTION
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 2301N device to be connected
to expand the system up to 8 entrances. When connecting 2x2301N the polarity of the bus between the Art.2301N's must be observed. When connect-
ing 2x2301N's the BUS output of the first exchanger must be linked to the AUX input of the second exchanger and then onto the apartments. The polari-
ties are not relevant if there is only one 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 entrances 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 2x2301N, the 2x2321/P power supplies only connect to the 2301N at which the AUX connection is used. (The one supplying the apart-
ments).
