Quick Start Guide
LC-202P/LC-208P
3.7 Cable Requirements
• RS-232 Serial Cable
-
four conductor, shielded, stranded AWG 24 wire (Belden 9534 or a heavier gauge)
- 50 foot maximum length (per RS-232 industry specification – greater lengths are not
recommended)
• RS-485 Network Cable
-
one twisted, shielded pair of conductors, stranded, AWG 24 wire (Belden 9501 or a heavier
gauge)
- 4,000 foot total network length (per RS-485 industry specification – greater lengths are not
recommended)
• Input Power
-
two conductor, stranded, AWG 18 wire (Belden 8461 or a heavier gauge)
- 200 foot maximum length
NOTE: On long power cable runs, the cable resistance causes a drop in voltage at the end of the
cable run. Be sure your power supply provides 12 VDC at the end of the cable run.
• Reader to Panel
-
six conductor, shielded, stranded AWG 24 wire (Belden 9536 or a heavier gauge)
• Output Connections
-
two conductor, stranded AWG 22 (Belden 9532 or a heavier gauge)
NOTE: The Floor Control Relay may require a heavier gauge of wire depending upon the current
demands of the elevator panel and the length of the wiring run.
NOTE: If plenum cable is required, please reference the Belden equivalent to the cable listed above.
4.0 Controller Installation
Sections 4.1 and 4.2 are quick lists of things to do and to not do when installing LC-202P and LC-
208P panels.
4.1 Do
• Plan ahead to meet power and telephone requirements for your system (1 phone line for the host
computer and one for each master LC-200P controller in each network).
• Mount controllers in environmentally suitable areas – they require protection from weather and
from temperature/humidity extremes.
• Mount the controller at least 3 feet away from the controller's power supply to prevent EMI
radiated from the power supply from affecting the controller.
• Use the enclosure as a mounting template to mark drilling holes for permanent mounting.
