Protection from weather Gasket at edge of cover, grommet at cable entrance
(Use shield or housing when required.)
2.2 CABLE EXITING FROM LR-2000 READER
The cable that is integrated into the LR-2000 is 22 gauge, 10 conductors, stranded wire, color-coded insulation, not twisted pairs,
overall 100% shielded, 30 inches long. (The connectors on the reader’s cable, when shipped, have no practical use. The installer
removes these connectors and strips the insulation.)
Color assignment:
Red......................... DC power, positive
Orange ................... RS-232 interface, Transmit Data (Connect to controller’s Receive Data.)
Yellow ................... Enable RF transmission (Connect to reader’s black wire for arming.)
Green ..................... Wiegand interface, Data-0
Blue ....................... Data-Common (For either Wiegand or RS-232 interface. Do not tie to black wire.)
Violet ..................... RS-232 interface, Receive Data (Connect to controller’s Transmit Data.)
Brown .................... (not used)
Black...................... DC power, negative (Do not ground.)
White ..................... Wiegand interface, Data-1
(No insulation)....... Drain wire (Connect to shields of extended cables. Do not ground.)
2.3 EXTENDED CABLE FROM READER TO PANEL AND POWER SUPPLY
The LR-2000 reader requires cables with particular specifications. If the installation will use separate cables from the reader
to the power supply, and from the reader to the reader input panel, use these specifications –
Power cable
: 18 gauge, 2 conductors, stranded wire, color-coded insulation, overall 100% shielded, high quality.
Data cable
: 22 gauge, 3 conductors, stranded wire, color-coded insulation, not twisted pairs, overall 100% shielded, high quality.
