Behind panel installation
The requisite for the installation of the Doortello Business BG version is that there is
already an exiting plate with a speaker grid available. The Doortello Business BG has
been especially developed for this type of use. As the form and technical details of
the plat with the speaker grid may differ from side to side we don’t have the
possibility to provide here precise installation instructions. It is very important that
the microphone is placed precisely in correspondence with a hole to the outside. If
necessary a hole has to be drilled. For a better speech quality of the speaker phone
the unit has installed flush fitted with the plate.
Using the available plastic frame adapters also the ES module can be used for
installation in letter boxes, pedestals and similar installations.
Flush and wall mounted installation
Please read carefully this user guide before you install the unit. Take care about the
security advices. Diregarding the warnings may be against existing laws or cause
dangerous situations.
Please note!
Think any time during installation at your own safety! Be careful and
disconnect the 230 V power supply before connecting the external power
supply unit. Before you touch any cable ensure that no voltage is present on
the line. Please consider that it can be against safety rules to run low and
high power cables in the same duct. An installation of 230 V cable inside the
door station is forbidden by law. If you have to drive high power circuits with
the internal driver contact of the device you have to use external high power
relais (like the 1471, see also the chapter
Options
)
Security advices
For the flush and wall mounted installation of the device the modular Doortello
Business door station has to be used. This program offers you a wide range of
different flush and wall mounting cases, as well as different pedestals. The
Doortello Business ES device is installed as one of the modules of the modular
door station. The single modules are conneted together using the delivered flat
cable. More details about the installation of the Doortello Business modular door
station can be found in the documentation delivered with the cases and modules.
Please note!
NEVER install a ES version behind an existing panel. This might cause heavy
disturbances to the speaker phone making his use impossible. For behind
panel installation use only the BG version!
