e) Connection of 2 actuators connected on the same riser
line
. One actuator with input command (i.e.: a button or
sensor) and one actuator with output switching (i.e.: connec-
tion to relay to actuate staircase lights, electrical door locks,
etc.)

- How to activate a relay 1471 or 1471E or 1472 using the OUT
and COM commands.
Attention: you can only use these Farfisa relays and the
actuator must be suitably programmed.
HOW TO CONNECT THE DOORKEEPER EXCHANGER
1
The in/out connection on the doorkeeper exchanger from the door
station (PE) and the internal line (PI).
2
The doorkeeper exchanger connection from the door station (PE) and
the internal lines (PI) through the DM2421 distributor-switcher.
3
Connection of the doorkeeper exchanger to one of the DM2444 riser
distributor outputs.
Attention! Remove the imped-
ance between the 2 terminals
LO in the junction box of door-
keeper exchanger.

In every installation diagram the most suitable points for connecting the
doorkeeper exchanger are marked with a diamond. The number inside
indicates the usable types of connection from those shown in this section.
Attention! Program only the
F1 interval on the DM2421
distributor line L2 inserting the
address of the PDX2000
doorkeeper exchanger
(default 201).
Attention! Program the DM2444 distributor LO4 output inserting the address
of the PDX2000 doorkeeper exchanger (default 201). The other DM2444
inputs and outputs must be programmed following the indications on the
installation schematic.
