16. Switching contact 2 (NO= normally open, NC= normally closed and COM= 
common output of the switch). 
17. Connector  8  –  for  connecting  8 
pushbuttons (integrated expansion). For 
connection  please  use  an 
interconnection  cable  Fermax  PBX 
CC8.  Each  colour  of  the  cable  is 
assigned  exactly  for  a  specific 
pushbutton – see picture 3. 
Connection of pushbuttons: 
blue  = 3rd pushbutton 
brown  = 4th pushbutton 
yellow  = 5th pushbutton 
red  = 6th pushbutton 
white  = 7th pushbutton 
green  = 8th pushbutton 
orange  = 9th pushbutton 
black  = 10th pushbutton 
The  numbers  of  pushbuttons  begin  with  3, because  the first two buttons 
are integrated on the basic panel.  
18. Connector  5  –  connection  of  the  8-pushbutton  expansion  Fermax  PBX 
EXP or the keypad Fermax PBX KEY. The connection is done via Fermax 
PBX CC5 cable. It is a data connection only. Power supply of illumination 
and the common output is on the Connector 3.  
19. Connector 3 –  it is used for  connection of  the power supply and the 
common output  of  the pushbuttons.  The  original Fermax  cable  is used 
(Fermax PBX CC3). 
20. Jumper Light enables switching on/off the illumination of visit cards. 
21. Switching  contact of the 2nd  switch (NO=normally  open, NC=normally 
closed and COM=common output of the switch). 
22.  When  using  Fermax  IP  DP,  it  is  suggested  to  use  either  an  alternating 
power supply voltage min. 10VAC – max. 15VAC or a direct power supply 
voltage min. 12VDC - max. - 18VDC. which is connected to the connector 
"12V". The load of the power supply depends on the number of modules 
used, because it is used also for powering the illumination of visit cards – if 
the  max.  number  of  pushbutton  panels  is  used,  the  power  consumption 
does not go beyond 500mA. This power  supply  can be also used  for 
powering  the  electrical  locks,  then  you  need  to  calculate  alsko  with  the 
power consumption of electrical locks. Usually it is enough to use a power 
supply of 12VAC/1A÷2A.
