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
on 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.
