24VDC Connection to the SP4-TZC
Apply power to the 24VDC Power Supply. The “POWER” LED indicator will turn ON. The
“RS485 COM1 ACTIVE” LED indicator should be BLINKING. The “STANDBY/RUN”
LED will BLINK for a maximum of 1 minute before becoming solid ON. See Figure 12 for
LED indicator locations.
NOTE: If an SP4-APS splitter is not energized during this process, the SP4-TZC will not “see” it and will
go to the next splitter. This will affect the order of the zone codes.
NOTE: If the “TROUBLE” LED indicator is ON, and the “SPLITTER MISMATCH” LED indicator is
ON, one or more of the CLASS switches on the SP4-APS splitters is in the wrong position. See
Figure 12 for LED indicator locations. Check the CLASS Switch on each splitter and make sure
all are in CLASS “A” or CLASS “B” as desired.
