Section 3: Configuring the AMPS-24
3.1 SLC Addressing
When the AMPS-24 communicates via the SLC, the installer must reserve sequential SLC
addresses (an address block) equal to the number of addresses that will be consumed by the
AMPS-24. Determining the size of the address block and setting the SLC base address is
described in this section.
3.1.1 Determining Address Consumption
Software determines the AMPS-24 address consumption. An AMPS-24 can occupy either one or
five addresses on an SLC. The AMPS-24 will consume five addresses on the SLC if configured for
five-point trouble reporting. If trouble reporting is not selected, the AMPS-24 will only consume
one address. Table 3.1 details address consumption.
NOTE:
An AMPS-24 communicating over the EIA-485 protocol will not require an SLC address
block. See Section 3.3, “Configuring the Network Annunciator” for more information.
!
CAUTION:
Always select “SLC Trouble Reporting” when connecting the AMPS-24 to an NFS2-3030.
