Label Material and Printing
Every
Helios
delivery includes a sheet of transparent foil that can be easily
printed, with a laser printer. Cut the printed foil into pieces and insert the labels into the
name plates. Do not use paper to avoid water logging.
Make sure that the text does not cover up the red arrows printed on the name
plate, we recommend you to print the foil using a template (MS Word), available at
www.2n.cz .

7. Electrical Installation
Compatibility
Helios
is designed for conventional, analogue telephone lines and works regardless of
polarity and line parameters.(Refer to the Technical Parameters) and uses tone (DTMF)
or pulse dialling to be programmed. Normally, it is connected to a PBX line however It
can also be connected to an analogue line or the GSM interface providing a wireless
installation.
Connection to Telephone Line
Connect
Helios
simply using LINE terminals. The advantage is that the
Helios
requires no power supply because all power is fed from the telephone line – except for
the button backlight and electric lock, if connected. Nevertheless,
Helios
can work
without these circuits too and sends an acoustic signal on having been connected to a
line (or after having been disconnected from the line for a defined period of time).
