Figure 1-1: NROM-2.0/2.5 with 1 SIB-NET Chip
• Open the Display Interface Assembly door.
• Observing proper orientation and ensuring that none
of the pins are bent, insert the ROM into the socket
for U15 on the SIB-NET
• Close the DIA door.
• Warning: Software must be compatible system-
wide. When not completely sure about compatibil-
ity, consult the factory before changing ROMs.
WARNING: You must have either a NROM-2.0/2.5 (AM2020) or N1ROM-2.0/2.5 (AFP1010) software kit
installed in the system. The NROM-2.0/2.5 software kit contains: 1 SIB-NET chip (see Figure 1-1), 10 LIB
chips, 1 CPU-2020 chip and 1 DIA-2020 chip. The N1ROM-2.0/2.5 software kit contains: 1 SIB-NET chip, 2
LIB-200 chips, 1 CPU-2 chip and 1 DIA-1010 chip. The entire network must contain the same version of
NOTIFIRENET
software, either Version 2.0 or 2.5. Improper system operation will result if the ver-
sions are not the same.
Software Combination Compatibility Warning: All software part numbers are not compatible with each
other. Improper mixing of software part numbers can compromise Life Safety functions. If unsure about the
compatibility of a particular software combination, consult the factory.
This software is not compatible with earlier versions of CGAS, AMNET, AUTOPLEXOR and VGAS/UNINET
systems. Software in these items must be upgraded for compatibility.
Section 1.2: Mounting the Interconnect Chassis Assemblies
The AM2020/AFP1010 system can use one to three Interconnect Chassis Assemblies (ICA-4/ICA-4L), depend-
ing on the specific installation requirements (the AFP1010 requires only one). If using more than one ICA-4/
ICA-4L, interconnect each ICA-4/ICA-4L before connection to the backbox by mating the plug connector on
one chassis to the socket connector on the other (no cable required). Align the entire ICA-4/ICA-4L assemblies
over the studs in the backbox. Connect a chassis grounding cable (71073) for each board installed on the ICA-
4/ICA-4L to an ICA-4/ICA-4L stud. Secure the assemblies and cables with the provided nuts and washers.
Each ICA-4/ICA-4L is marked with “TOP” for proper orientation. NOTE: The ICA-4L with the SIB-NET
interface card must be in the top position in the backbox!
WARNING: When connecting an ICA-4 to an ICA-4L, there is an extra pin which must go in front of the
connector (see Figure 1-2).
The ICA-4L is a low-profile mounting chassis that replaces the ICA-4 in all BE-1010N and BE-2020N basic
equipment kits. The ICA-4L is fully compatible with both CAB-2 and CAB-3 series cabinets and the ICA-4
chassis.
