The AIM-200 communicates with intelligent and addressable initiating,
monitor and control devices through a communications loop. The
FC-2000 can support up to ten communications loops, each controlled by
an AIM-200 module. The communications loops can be wired as
non-redundant (Figure 9), redundant (Figure 12), or isolated redundant
(Figure 13).
Isolator modules (M500XJ) permit a zone of detectors and modules to be
electrically isolated from the remainder of the communications loop,
allowing critical loop components to function in the event of a circuit fault
(see Figures 13 and 18).
Addressable monitor modules (M500MJ, M502MJ, and M501MJ) allow
the AIM-200 to monitor entire circuits of conventional normally open
contacts, alarm initiating devices, manual pull stations, 4
detectors, heat detectors, and waterflow and supervisory devices
(Figures 21 and 22). A type of monitor module, the addressable
BGX-101L, provides point annunciation of manual pull stations
(Figure 27).
