Appendix A, B and C respectively for details and
specific installation requirements.
MAJOR COMPONENT DESCRIPTIONS
The system consists of three basic components (see
Figure I-1):
INTELLIGENT FIELD DEVICES ON LOCAL OPERATING
NETWORK/SIGNALING LINE CIRCUIT (LON™/SLC)
The LON/SLC is a fault tolerant, two wire, digital
communication network, arranged in a loop starting and
ending at the Local Control Unit. The LON/SLC
supports up to 244 intelligent field devices spread over
a distance of up to 32,500 feet (10,000 meters). The
LON/SLC serves as the Signaling Line Circuit (SLC) for
the fire detection/suppression aspects of the system.
LOCAL CONTROL UNIT (LCU)
The LCU functions as the “heart” of the Eagle Quantum
system. The LCU contains three replaceable modules
