Table 3-1 — LCN Coax Cable Components
Maximum cable length 300 meters (984 feet)
Coaxial cable type System Cables (LCN coaxial-cable set) are available in standard and
variable lengths. Each set consists of two cables, marked A & B, in the
following lengths:
Honeywell Part Number Length (meters)
51308112- 003 3 meters
008 8 meters
015 15 meters
030 30 meters
050 50 meters
100 100 meters
200 200 meters
XXX = Variable length Max = 300 meters
Minimum cable length
between nodes
2 meters (78 inches). Use 51308111-002, which consists of two
cables, one marked Cable A and one marked Cable B. All LCN cables
must be marked. It is essential that Cable A is Cable A to all nodes.
Make certain that cables are not crossed. Do not substitute with
unauthorized cables.
BNC Tee-connectors 51190728-105. Note that these are not the same as those used on
the Data Hiway.
Termination resistors 30732052-001, are required at each end of both coaxial cables.
For fiber optic cable ordering information, see
LCN Guidelines
in the
LCN Installation
binder.
LCN cabling must not be routed outside the control room building. Consider LCN Extenders
(LCNE) and Fiber Optic cables for outside conditions.
See Section 2 of
LCN Guidelines
in the
LCN Installation
binder for specific LCN cabling rules.
Use only Honeywell supplied LCN cabling, and always connect cables marked "A" to the
A connector of a node, and cables marked "B" to B connector of a node (never interchange
"A" and "B" cables). It is strongly recommended that the color-coding system of marking
coax cable, T-connectors, terminators, and connectors (board) be used. These materials
are available from your Honeywell representative.
NOTE
LCN Coax Cable Color Code Cable A = Yellow Cable B = Green
