Application
Access door loudspeaker module
Plus for Siedle Vario with integrated
loudspeaker and microphone, as
well as additional audio amplifier
and noise filter.
Performance features:
• Front grille made of weather and
UV-resistant polycarbonate (via the
Access server)
• Loudspeaker, voice volume can be
adjusted
• Voice volume can be doubled via
the audio amplifier
• Durable electret microphone
• Light button with LED-lit light
symbol
• Connection of a ZAM 670-...
status display module for optical and
acoustic signalling of the operating
state is possible
• Acoustic feedback when pressing a
call button can be activated
Up to max. 48 call button modules
can be connected in any combina-
tion, allowing up to max. 192 call
buttons to be connected.
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.

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-

To use the additional supply, the
jumpers on the ATLM 671-... are
removed from b1/c1 to b/c and the
b/c terminals are directly connected
to the additional supply.
