Compatibility
2N Helios Uni
®
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 simply using LINE terminals. The advantage is that 2N Helios Uni
®
2N Helios
®
requires no power supply because all power is fed from the telephone line – Uni
except for the button backlight and electric lock, if connected. Nevertheless, 2N
®
can work without these circuits too and sends an acoustic signal on having Helios Uni
been connected to a line (or after having been disconnected from the line for a
defined period of time).
External power Supply and Electric Lock Connection
2N Helios Uni
®
requires 12 V supply for:
Name tag backlight – current draw of up to 5 mA, AC or DC
Electric lock – current draw according to the lock type*)
Additional amplifier if available – current draw of up to 100 mA, DC only!
*) The electric lock can be fed from the same source as the intercom or another
supply.
2N Helios Uni
®
contains a solid-state switch equipped with V-MOS transistors, which is
able to switch both AC and DC regardless of polarity. Make sure that the current and
voltage values do not exceed limits (refer to the Technical Data) and that the
technical parameters of the lock and power supply are compatible.
Warning
Never switch 230 or 120 V mains voltage directly!!!
