Introduction
2.1. General features
▸ Full-duplex hands-free phone
In standard mode, Behnke Series 5 Intercom
stations work exactly like a full-duplex hands-
free phone. In this mode, both parties to the
call may speak and listen at the same time.
Speaker volume and maximum connection
interval may be adjusted.
▸ Voice-controlled duplex operation with
additional amplifier
With an additional 15 V power supply, the
built-in amplifier may be activated.
When the additional amplifier is activated,
Behnke Series 5 Intercom stations are set
to voice-controlled duplex operation mode.
Depending on which party is currently
speaking, either speaker or microphone
will be energised to achieve higher
volumes without audio feedback. In case
the additional power supply is lost, the
system automatically returns to full-duplex
operations mode.
▸ Flexible remote set-up
Behnke Series 5 Intercom stations offer
numerous set-up options. The system is
set up remotely via a telephone with DTMF
dialling. To enter the set-up mode, please
enter the four-digit security code. By choosing
“reset”, the system will return to its default
settings.

introduCtion
Behnke Series 5 Intercom stations are high
quality hands-free phones that can be used like
a standard (analogue) desk telephone with an
analogue landline connection or as an analogue
extension to a telephone system. An additional
power supply is not necessary to use the basic
functions. The built-in relay enables a number
of control functions.
