5.1.1 Resetting the Network Configuration (Not SP4 Telzone
Programmer 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 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 for the SP4-TZC.
Make sure 24VDC is ON to the SP4-TZC and all SP4-APS splitters.
Press and hold the reset button for approximately 5 seconds until the all LED indicators
except the POWER LED indicator turn OFF.
Release the 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 before becoming solid ON.
Install the enclosure cover.
