24 Hardware Installation—Installing the IFC-1010/2020
Any board with a 15-position receptacle suitable for use on the ICA-4 may
also be mounted on the 16-pin plug ICA-4L. The following nine boards
have 15-position receptacles and may be installed on the ICA-4L:
• CPU-2
• SIB-232
• CCM-1
When installing any board consisting of 15-position receptacles on the
16-pin plug ICA-4L, only Pins 1 through 15 will engage. The 16th pin will
remain on the outside of the board receptacle (refer to Figure 15).
A 16-position ICA-4L is required for Local mode general alarm bus
operation (refer to Loop Interface Boards [LIB-200, LIB-200 A, and
LIB-400] section).
