It can be used for DUO System when the installation
includes one or more main common door stations and risers
with or without secondary door stations.
The device is basically a relay used to switch a common line
(LP) over two switched lines (L1 normally closed and L2
normally open).
Switching between common line LP and exchanged lines L1
and L2 depends on the need to connect the users connected
to line L1 or line L2 to the common line.
To carry out this operation, the exchanger must be
programmed to define which users or external door stations
are connected to the lines.

ATTENTION:

BEFORE POWERING THE DEVICE (for detailed
information refer to "External door station connected to
line L2" and "Internal Users connected to line L2").
Warnings.
-Do not power the exchanger with the power supply used by
external door stations in the installation (6 max.).
- In case of multiple exchangers in the same doorkeeper
exchanger, they can be powered by the same power supply
unit. Otherwise, it is recommended to use separate power
supplies to avoid any interference.
PROGRAMMING
To ensure correct operation of the system, the exchanger
must be programmed to identify users (internal stations) or
external door stations connected to the terminals of the
secondary line L2; no programming is needed to identify
devices connected to the main line LP and secondary line
L1. Four numerical intervals are available to save the codes
of the devices connected to line L2. Codes of individual users
or numerical intervals (one lower and one higher value) can
be saved.
In case of installation with multiple exchangers, the user or
external door station code assigned to an exchanger cannot
be assigned to other exchangers. Each exchanger must have a group of users or
external door stations with univocal identification.
Programming must be executed according to the type of connected device.
External door station connected to line L2.
- When an external door station is connected to the exchanger line L2, before
65
powering up the installation, it is necessary to set all SW2 microswitches on

- Then the exchanger numerical interval 1 must be
programmed (see chapter "numerical interval
programming - page 4.14") by entering the address of
the external door station (address that must be previously
programmed also in the external door station - see the
external door station programming in the chapter 3).
Example. If the external door station connected to line
L2 was coded with code 232, the exchanger must be
programmed by saving code 232 in numerical interval 1.
The other numerical intervals must not be programmed.
Internal Users connected to L2.
- When the internal users are connected
to the exchanger line L2, before
powering up the installation, it is
necessary to set all SW2 micro-
switches on OFF.
- Then the user addresses must be
entered according to the procedure
13Vac ± 1
illustrated in chapter "numerical
0.1 A
interval programming (see page
4.14)" according to the following
0° ÷ +50°C
instructions:
- if user numbers are progressive, the
addresses of the first and last user in
the group must be programmed in
numerical interval 1 (addresses must be assigned to
users during programming - see the internal users
programming in the chapter 2).
- In case of various groups of users - each group being
composed of users with progressive addresses - the
other three numerical intervals can be used to code the
groups.
- Users must be saved individually (one user for each
interval) in case of one or more users connected to the
installation with an address that is not included in any group.
Example of installation with 4 risers (buildings or staircases).
See programming on bottom of page.
- Building "a" with users coded with numbers from 1 to 25. The exchanger
numerical interval 1 must be programmed with number 1 as first user and number
25 as last user; all the other numbers (from 2 to 24) will be automatically included
in the interval. The other numerical intervals must not be programmed.
- Building "b" with users coded with numbers from 30 to 50 and from 60 to 75. The
exchanger numerical interval 1 must be programmed with number 30 as first user
and number 50 as last user.
Numerical interval 2 must be programmed with number 60 as first user and
number 75 as last user. The other numerical intervals must not be programmed.
- Building "c" with users coded with numbers from 80 to 101, from 107 to 116 and
individual users 28 and 127. The exchanger numerical interval 1 must be
programmed with number 80 as first user and number 101 as last user.
Numerical interval 2 must be programmed with number 107 as first user and
number 116 as last user.
Numerical interval 3 must be programmed with number 28 only and numerical
interval 4 must be programmed with number 127 only.
- Being connected to output L1 of the last exchanger, building "d" is not
programmed.
Entering the programming mod
- Move the mobile jumper J1 from position 1-2 to 2-3. The red LED turns on and
stays on.
