Audio Level Conversion Card
Installation Instructions
ModelALCC
INTRODUCTION The Model ALCC from Siemens Industry, Inc., is an
Audio Level Conversion Card that contains two audio
channels. Each channel is capable of accepting speaker-
level audio at 70VRMS from Siemens amplifier models
ZAC-30 (MXL) and ZAC-40 (XLS/Desigo Fire Safety
Modular/Cerberus PRO Modular).There is a single
output channel of line-level audio for connection to the
AIC (Audio Input Card).
The ALCC adds system-wide live emergency paging
capability to networked XLS/Desigo Fire Safety
Modular/Cerberus PRO Modular Voice systems as well
as an all-call function for XLS/Desigo Fire Safety
Modular/Cerberus PRO Modular-based MXL/XLS/
Desigo Fire Safety Modular/Cerberus PRO Modular
hybrid systems. Located on the receiving end in up to
63 remote XLS/Desigo Fire Safety Modular/Cerberus
PRO Modular nodes, the ALCC converts the audio
signal generated by the amplifiers located in the
primary and secondary paging stations into a form that
is compatible with AICs located in the remote stations.
The ALCC is transparent to the host system. As such, it
supports all styles of wiring supported by ZAC-40 (XLS/
Desigo Fire Safety Modular/Cerberus PRO Modular) as
well as ZAC-30 (MXL) amplifiers. It provides supervision
by constantly monitoring its two audio channels,
reporting faults both visually and through the down-
stream AIC. Furthermore, the ALCC contains audio
detection and channel selection circuitry that prioritizes
incoming audio, enables the appropriate channel,
closes the AIC audio active contact, or cuts the output
of the ALCC to generate an AIC trouble, depending on
the presence of incoming audio or circuit faults. Finally,
all XLS/Desigo Fire Safety Modular/Cerberus PRO
Modular functions are configured in the Zeus program-
ming tool via standard logic functions with no need for
special software or hardware upgrades.
• Two isolated audio channels, 70VRMS input from ZAC-30 (MXL) or ZAC-40
(XLS/Desigo Fire Safety Modular/Cerberus PRO Modular) amplifiers.
• Single channel output to the AIC, 0.775VRMS.
• ±6dBu output adjustment capability, independent for each channel.
• Up to 63 ALCCs on a single audio riser.

• Visually indicated input channel prioritization control logic based on audio
activity and fault detection.
• Audio path supervision for both channels, reported visually by LEDs and to
the system by the AIC audio input supervision circuitry.
• All-analog circuitry makes the ALCC completely transparent to the overlying
system structure.
OPERATION The ALCC provides the capability of conducting a global emergency page across
multiple remote XLS/Desigo Fire Safety Modular/Cerberus PRO Modular nodes, up to
63 nodes per audio riser. The emergency page originates at an XLS/Desigo Fire
Safety Modular/Cerberus PRO Modular or MXL global paging station, where it is
broadcast at 70VRMS over an audio riser by a ZAC-40 (XLS/Desigo Fire Safety
Modular/Cerberus PRO Modular) or ZAC-30 (MXL) amplifier. A single remote XLS/
Desigo Fire Safety Modular/Cerberus PRO Modular node contains one ALCC, which
steps the incoming speaker-level audio down to line-level audio that is compatible
with the AIC audio input (0.775VMRS, independently adjustable to ±6dBu). The AIC
digitizes the audio, which is subsequently transmitted by a DAC-NET to local
amplifier(s) for broadcast over the local speaker zones.The ALCC incorporates two
independent audio channels and is therefore capable of supporting two global paging
stations. In case of a simultaneous page, the ALCC control logic prioritizes the
primary channel over the secondary channel. On-board audio detection circuitry
monitors the audio risers for incoming audio, while supervision circuitry reports any
issues with the audio path via front-accessible LEDs, and, if necessary, disconnects
its output from the AIC input, causing a trouble to be reported to the system. The
ALCC relies on the originating amplifier for supervision of the audio risers, and on the
AIC for supervision of the connection to the ALCC. Since the AIC monitors the
presence of signal on its audio input, it is responsible for reporting audio path faults
to the XLS/Desigo Fire Safety Modular/Cerberus PRO Modular system.
The ALCC contains no digital circuitry and integrates seamlessly into the existing
XLS/Desigo Fire Safety Modular/Cerberus PRO Modular framework, as it is com-
pletely transparent to the overlying system structure.
Refer to the ALCC Usage Restrictions on page 8.

Installing The ALCC
WIRING
Remove all system power before installation, first battery then AC. (To power up,
connect the AC first, then the battery.)
All field wiring of the ALCC is connected to the CC-2/CC-5 terminal blocks located
above and below the card cage slot, in which it is installed.
To connect external wiring:
1. Loosen the screw of the terminal by turning it counterclockwise.
2. Insert the wire into the side of the terminal block.
3. Tighten the screw of the terminal block by turning it clockwise.
For all versions of Zeus earlier than 7.0, the ALCC is not
an option under CC-5 or CC-2. As a result, such proper-
ties as card cage slot availability and battery / power
supply current draw must be accounted for manually
in those Zeus versions prior to 7.0.
It is recommended to install the ALCC in a slot adjacent
to the AIC.
INSTALLATION The ALCC plugs perpendicularly into a CC-2 or CC-5 slot via two 96-pin DIN connec-
tors and can occupy any slot in the card cage.
Slide the ALCC card into the card guides front bezel up, until the card edge connec-
tors contact the motherboard receptacles. The LEDs, test buttons, adjustment
potentiometers, and the legend should be visible and accessible.
Verify that the card edge connectors align properly with
the motherboard receptacles.There is only one correct
way to plug in the card. If it does not align, DO NOT
FORCE the card.
Place thumbs on the front panel adjacent to the captive
screws and gently apply even pressure on the card
until the connectors plug firmly into the motherboard
receptacles. Secure the ALCC to the card cage with
captive screws.
Power up the system and verify that the ALCC power
LED turns ON.
