The architecture of an IP Fire Series^TM fire control network is comprised of a series of IP-based distributable modules. These modules include alternate configurations of analog loop and NAC circuit modules (ALM-xy), standard display modules (SDM), annunciator control modules (ACM) and other specialized modules noted in other documents.

The Analog Loop Module (ALM) communicates with all other modules installed on the network through an Ethernet connection and is addressed through the ALM’s unique IP address.

The ALM manages Class A/B Signaling Line Circuits (SLC), Class A/B Notification Appliance Circuits (NAC) or both, depending on the module configuration. The number of each type of circuit is specified by the trailing 2 digits in the ALM part number. Thus, an ALM-12 would have a single SLC and two NAC circuits.

Once programmed, each ALM maintains an integral 3000 event history log and will continue to operate its connected circuits even if communication with the remaining network is severed. Upon rejoining the network, the ALM will synchronize its data with the remaining modules.

IP Fire Series^TM systems feature SmokeClear^TM to report when smoke has cleared the chamber of any detection device. This information is reported to the panel and recorded in the history log allowing first responders to determine the length of time that smoke was present at any given location when evaluating conditions upon arrival. SmokeClear^TM will also put a notification on the system when pull stations have been reset signaling that the IP Fire^TM system can be reset.
