Power fail is not supported on the SDC; therefore no jumper is required. This is labeled in the diagram as “NOT USED.”External tamper wiringNote:Input status LEDs will be off when the tamper device is in closed position or the jumper is installed.77.8Power and CommunicationsFor its power input, the SDC requires a 12 to 24 VDC ± 10% power source for it input power.Wire the power input with 18 AWG (minimum) twisted pair cable.Power SourceRequirementsCurrentDC power sourceIsolated, non-switching, regulated DC power700mA for 12VDC 350mA for 24VDCrevision 6 — 381LNL-1300-U Single Door Controller ModulePower source wiringNotes:Be sure to observe polarity.Do not use an AC transformer to directly power the Single Reader SDC Interface Module.77.9UL Listed InstallationsFor UL Installations, the following must be observed:All field wiring terminals are suitable for single wire only.Use 22 AWG minimum for wiring of RS-485, Input I1, and reader data.
