Can you connect multiple channels (card cages) to a single CIB to save cost? Yes, so long as you are
connecting only one type of comparator to one CIB. For example, in a system that had 6 Spectra-TAC
channels each with only 4 receivers, one CIB could be connected to 2 channels, and only 3 CIBs would
be required, but there would be no pre-wired expansion. When you control multiple channels or
comparator card cages, be sure to use the punch block wiring option to make the field wiring easier. If
you control multiple DIGITAC cages from one CIB, you can’t use the DIGITAC bracket and ribbon
cable mount.
A standard configured system can have a maximum of 20 comparator modules (CIBs and AIBs) on a
network segment. Larger systems can be custom-configured by CTI Products, Inc. If you need more
than 20 CIBs and AIBs on one network, call a system engineer at CTI Products, Inc.
