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 mes-
sages directly with the PMI.
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.
The DAC-NET contains various on-board tones and audio messages.
FMT Fireman’s Master The FMT Fireman’s Master Telephone provides firefighters 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.
FTS Series FireFighter’s The FTS Series of FireFighter’s Telephone Stations consists of the FTS,
Telephone Stations FTS-P, FTS-C, FTS-CL and FTS-PCL models. Any of the models in the FTS Series can
mount into either the FB-300 flush backbox or the FB-301S surface backbox. The
backboxes are mounted on the wall of the facility in accordance with local mounting
codes in locations that provide easy access.
LPB Local Page Board The LPB (Local Page Board) is used to connect the alarm microphone,
mounted in the LVM (Live Voice Microphone), and the voice system
internal telephone system. The LPB converts the two analog input
signals into the system’s internal digital format. Additionally the LPB
provides one analog output to connect the monitor speaker, mounted
in the LVM. This output signal is one of the eight internal voice audio
channels selectable at the voice control panel.
The microphone signal wiring between LVM and LPB is supervised.
The microphone audio input of the LPB is not transformer isolated
(each LVM microphone output is transformer isolated). The audio input
from the telephone riser is transformer isolated.
Each of the three audio channels can be configured independently via
the Zeus tool. Each audio channel can be controlled automatically via
system logic, dependant on its individual configuration or manually by
using the voice control panel.
