FIREFINDER-XLS INSTALLATION, OPERATION AND MAINTENANCE MANUAL | CHAPTER 1
DAC-NET (D-NET) The DAC-NET is the CAN-BUS master for all CAN modules. One
DAC-NET is required in each enclosure. It is the source point for eight
digital audio channels and communicates audio data via the ASI-BUS to
all digital audio cards. It communicates all instructions and messages
directly with the PMI/PMI-2/PMI-3.
The DAC-NET contains an optional LPB (Local Page Interface Board)
which has to be mounted piggyback. This CAN module with a fixed CAN
address provides the microphone input from the LVM, the telephone riser
input from the FMT, and an output for the monitor speaker on the LVM. It
provides network communication (D-NET) between enclosures (nodes).
The network can be wired either Style 4 or Style 7. Each DAC-NET
occupies one D-NET address.
In Canada, ULC S524 requires that all interconnecting data communications links for
networks be wired DCLC (style 7) except for dedicated network communication
annunciators.
The DAC-NET contains various on-board tones and audio messages.
FMT-A-ADPT Class A The FMT-A-ADPT provides the FMT with Class A riser capability. The
Riser Module telephone riser is supervised by the primary FMT.
FMT Fireman’s Master The FMT Fireman’s Master Telephone provides first responders with
Telephone an emergency telephone system for communication with remote
locations. The FMT is located in the main FireFinder-XLS enclosure
and includes a handset for the operator of the telephone system.
