Application
Access door loudspeaker Plus with
integrated loudspeaker and micro-
phone, as well as additional audio
amplifier and noise filter.
Performance features:
• Loudspeaker, voice volume can be
adjusted (via the Access server)
• Voice volume can be doubled via
the audio amplifier
• Durable electret microphone
• Connection of a status display for
optical and acoustic signalling of the
operating state is possible
• Acoustic feedback when pressing a
call button can be activated
For use in entrance areas with very
loud background noises, such as
lorry entrances or loud or disruptive
wind noise.
The integrated noise filter helps filter
out unwanted background noises
in the lower frequency range in the
microphone branch so visitors can
be clearly understood at the indoor
station.
With the audio amplifier, the sound
pressure level at the door station can
be increased by up to 7 dB. This cor-
responds to approximately double
the acoustic power.
The voice volume setting can be
configured centrally on the Access
server.
The door loudspeaker is connected
to the structured wiring in the
building using the ATLC/NG 670-...
interface.

Mounting, installation and servicing
work on electrical devices may only
be performed by a suitably qualified
electrician.
Mounting and service
More detailed information regarding
mounting and module replacement
can be found in the installation
instructions for the Classic door
station.
Installation
The audio amplifier is supplied via
the ATLC 670-... Information about
the supply limits if no additional
power supply is used can be found
in the table on page 4. If further
modules are to be connected which
exceed the supply limits, an appro-
priate additional power supply (e.g.
TR 603-...) is required.
To use the additional supply, the
jumpers on the SATLM 671-... are
removed from b1/c1 to b/c and the
b/c terminals are directly connected
to the additional supply.
