3.0 Cable Requirements
RS-232 Serial Cable
•
three conductor, shielded, stranded, AWG 24 wire (Belden 9533 or a larger 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 larger gauge)
• 4,000 foot total network length (per RS-485 industry specification)
• extended network configurations are possible – refer to the Network Wiring Application Note (P/N 01824-002) for
extended network configurations of up to 5,000 feet per star line and 16,000 feet total network length
Telephone
•
1 pair copper phone line
NOTE: EntraGuard Platinum is not to be used with a Centrex, PBX, or digital phone line. Only use a Plain Old
Telephone Service (POTS) analog phone line.
Input Power
•
two conductor, stranded, AWG 18 wire (Belden 8461 or a larger gauge)
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 does provide 12 VDC at the end of the cable run. Power supply should be measured under full load (with the
unit attached and all other devices connected).
Earth Ground
• Single conductor, AWG 18 wire (or a larger gauge)
1
Input and Output Connections
•
two conductor, stranded, AWG 22 (or a larger gauge)
NOTE: The Lock Output relay may require a heavier gauge of wire depending upon the current demands of the lock and
the length of the lock wiring run.
NOTE: If plenum cable is required, please reference the Belden plenum equivalent to the cables listed above.
1. Ground wire is green, with or without yellow tracer.
