Section 2.3 Mounting the ICA-4L
The AM2020/AFP1010 system may use one to three Interconnect Chassis Assemblies (ICA), depending on the
specific installation requirements. The AFP1010 requires only one ICA when using LIB-400s.
The ICA-4L is a low profile mounting chassis that currently replaces the ICA-4 in all BE-1010N and BE-2020N
basic equipment kits. The ICA-4L is compatible with both CAB-2 and CAB-3 cabinets and the ICA-4 chassis.
The ICA-4L is required when employing the LIB-400 local mode general alarm bus (refer to The Loop Interface
Boards, Section 4.2 of this chapter).
When using more than one ICA-4L, interconnect each ICA-4L before mounting it to the backbox by mating the
male connector on one chassis to the female connector on the other (no cable is required). Align all ICA-4L
Assemblies over the studs in the backbox. Connect chassis grounding cable, part number 71073 for each board
to be installed on the ICA-4L to an ICA-4L stud. Secure the assemblies and cables with the nuts and washers
provided. Each ICA-4L is marked with "TOP" for proper orientation.
The ICA-4L is recommended when installing the SIB-2048A, SIB-NET, LIB-200A, or LIB-400 because a 16-
position receptacle is mated with a 16-pin plug. The LIB-400 is used to illustrate this in Figure 2.3-1.

The power cable part number 75378, (refer to Figure 2.3-2) is able to mate properly with the ICA-4L since it has
a 16 position receptacle. The power cable also has an 8-position receptacle to connect to the main power supply
(refer to Figure 2.3-3).
