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).
