Read the complete manual before attempting installation and activating the
system.
1. DESCRIPTION
The power supply modules can be used to power and programme an audio door com-
munication system. For large systems or systems using an external unit with LCD display
and/or video, a supplementary DC voltage power supply is needed.
Both power supply modules are designed for DIN-rail mounting. The maximum configuration
of an audio system is given in table 1.
The power supply modules operate at the standard mains voltage (230V~, 50Hz) and sup-
ply the system with DC voltage. These power supply modules not only allow connection of
the internal and external units but can also be used to control a door opener and/or a light
source. The activation times of the door opener and the lighting can both be set.
2. INSTALLATION
The power supply modules are suitable for DIN-rail cabinet mounting. You can connect the
power supply modules by connecting the mains supply to terminals 1 and 3 of the power
supply module. For the connection of the internal and external unit to the power supply
module, see fig.1.
Following cables can be used for connecting the internal and external unit(s): JYSTY(-F2) 3 x 2
x 0,8mm or TPVF 3 x 2 x 0,6mm (to some extent limits the size of the system, see table 2.).
Not all pairs are used in a system without video. Yet we do recommend to always provide
3 pairs in order to allow future extension to a video system.
POWER SUPPLY 20 (10-801)
If you only have 1 external and 1 internal unit, you can choose between 2- or 3-wire wiring.
In a 2-wire audio system (fig.1), you only need to jumper the P terminal (in the external unit)
and the a terminal for the nameplate to be illuminated. In case of a 3-wire connection (fig.1),
the P wire is connected to the external unit via the power supply. Therefore, terminals P and
'a' no longer need to be jumpered. For the internal units, a 2-wire connection is sufficient.
A door opener (optional) must be connected to terminals 16 and 17 of the power supply
module (POWER SUPPLY 20).
POWER SUPPLY 100 (10-802)
This power supply is only used for large systems. A 3-wire wiring to the external unit is thus
required. For wiring to the internal units, a 2-wire connection can still be used (fig. 2). The
power supply of the internal and external units is split up into 3 busses.
Connect the door opener (optional) to terminals 20 and 21 of the power supply module
(POWER SUPPLY 100).
