5.1.1 Resetting the Network Configuration (Not SP4 Telzone
Programmer 2 Programmed)
Resetting the network configuration is done when it appears that the paging system is corrupt or an SP4-
APS splitter has been added, removed or replaced. Should one of these conditions occur, and the SP4-TZC
has not been programmed using the SP4 Telzone Programmer 2 software, perform this procedure. If you
have made changes, use Appendix A at the end of this manual to update the new Zone Code location for
each zone and zone group.
The procedure is as follows:
Remove the enclosure cover from the SP4-TZC.
Make sure 24VDC is
ON
to the SP4-TZC and all SP4-APS splitters.
Press and hold the system reset button for approximately 5 seconds until the all LED indicators
except the “POWER” LED indicator turns
OFF
.
Release the system reset button. The SP4-TZC will begin finding and mapping the SP4-APS
splitters. The “RS485 COM1 ACTIVE” LED indicator should be
BLINKING
. The
“STANDBY/RUN” LED will
BLINK
for a maximum of 1 minute after which the
“STANDBY/RUN” LED will remain
ON
.
Install the enclosure cover.
