stranded, twisted pair cable for monitor points, DSMS, and REXs. Use

LED Input Status
Each input uses a Red, Yellow, or Green LED to show the input status.
Only one color will be on at a time for each input.
Table 6 lists the LED color and the corresponding input status.
Red LED indicates alert (nominal 500 ohms or 2K ohms).
Green LED indicates secure hardware state (nominal 1k ohms).
Yellow LED indicates supervision error (open circuit, shorted, or line
fault).
The RM-4E input status LEDs show flashing status if the RM-4E is
communicating with the apC or iSTAR and at least one input or
output is configured, or the reader is being used on a door. (The apC
or iSTAR needs a configured reason to communicate.)
