The 4090-9051 Supervised Individual Addressable Module (IAM) provide four-state
status information (NORMAL, OPEN, CURRENT-LIMITED, and SHORT) to the
4010 Fire Alarm Control Panel (FACP) via the IDNet™ channel. The IDNet channel
provides the communication link between Supervised IAM and 4010 FACP and
powers the entire IAM circuitry. A typical application for this module would be to
monitor a waterflow switch.
