Model DAC-NET
Digital Audio Card - NETWORK (500-035100 / S24235-B3-A5)
INTRODUCTION
The Model DAC-NET from Siemens Industry, Inc. is
the CAN-BUS master for all CAN modules. One DAC-
NET is required in each control panel and each
transponder. It is the source point for eight digital
audio channels and communicates audio data via ASI-
BUS to all digital audio cards.
There is one BACnet (Building Automation & Control
Network) interface. It communicates all instructions
and messages directly with the PMI/PMI-2/PMI-3
(CPC-DAC interface).
It provides network communication (D-NET) between
control panels and transponders (nodes). The
network can be wired either Class B or Class X. Each
DAC-NET occupies one D-NET address. The DAC-
NET contains various on board tones and audio
messages.
The DAC-NET can contain an optional LPB (Local
Page Board) which has to be mounted piggyback.
This CAN module has a fixed CAN address (100) and
provides two inputs. One is for the microphone
located at the LVM and the other connects the
internal telephone system. Additionally, the LPB
provides one output for the monitor speaker located
at the LVM. For more information refer to the LPB

Features
The D-NET is supervised for open, short and ground
fault. Each D-NET input / output is electrically
isolated. Wiring can be either Class B or Class X with
unshielded twisted pair. The maximum distance
between two DAC-NETs is 300m with cat3 cable,
900m with cat5 cable or 700m with cable 1pr.
18B FPLR / 1pr. 16B FPLR / 1pr. 14B FPLR. A
maximum wiring length can be up to 10 km
throughout the entire network with a maximum of
32 DAC-NET nodes. Up to 99 CAN sub-modules
are addressable. The system is able to handle
eight independent audio channels. Software updates for µC and D-NET
controller are downloadable. Tones and audio messages are downloadable.
Diagnostic LEDs for troubleshooting are located on the front panel of the
DAC-NET. Refer to Figure 1.
