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.
•
Readers to Panel
-
Wiegand Readers require seven conductor, shielded, stranded AWG 24 wire (Belden 9537
or a heavier gauge)
•
Panels Daisy-Chained
-
Wiegand Readers require three conductor, shielded, stranded AWG 24 wire (Belden 9533 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.
