1.4  Installation of DoorPhone VoIP Assembly 
1.4.1  Installation on Plaster 
By installation on plaster the only compact box 
-  Rain-Protective Cover KPDxx is used, which 
will  supersede  all  mechanical  parts  (MKxx, 
Canopy  xx  and  Fixing  Frame  xx).  The 
installation is made by screwing to the wall by 
means of dowels. See KPD1 on figure. 
1.4.2  Flush-Mounted Installation 
The MKxx mounting box is built-in wall. Be 
careful  in  orientation  of  assembling  holes 
when nearly MK1 square box is used  – it 
must be in vertical axis. The well-embedded box is 
shown on figure. 
The  Protecting  Frame  (provides  overlapping  of 
unevenness  after  mounting  box  walling-in)  and 
Canopy  (necessary  for  installation  in  external 
areas) form other accessories for flush-mounted installation. When installed in 
surroundings with possible water condensation (temperature changes) or water 
spraying  (rain)  it is  recommended  to  connect  the  jumper  on  basic  module  – 
heating ON. 
The board heating has two positive functions partly it heats up the electronics 
in winter at temperatures below –20°C (most details  with extended temperature 
range  has  guaranteed  parameters  from  –20°C)  and  par tly  with  external 
installation at  swift  temperature changes and  higher  air humidity by switched 
heating no water condensation occurs on basic guard board, which assures its 
reliable function. 
1.5  Change of nameplates 
The  first  step  is  dismantling  of  a 
fixing frame from module, where we 
want  to  change  a  nameplate.  It  can 
be  executed  by  unscrewing  of  two 
screws under plastic covers on fixing 
frame.  When  removing  the  fixing 
frame  we can see two  independent 
modules.  The front part (metallic) of 
the button module has to be first separated from plastic part in this way that we 
will put off the plastic lug, ensuring the front part on the right side. Each button 
has  its  separate  nameplate  hold  by  means  of  plastic  flag  (see  figure).  The 
paper  nameplates  can  be  printed  from  Excel  form  (to  be  downloaded on 
www.alphatech.cz).
