A multistationed integrated life safety system in which each station will be situated at a diffferent location and have complete capabilities in terms of local fire protection, fire detection, control and/or monitoring and controlling the security of an area. Each station communicates with four adjacent stations so that when an event occurs at one station, that station is programmed to cause that information or that new status to be transmitted to each of the four adjacent stations. Thus, each station will be interconnected or networked to four other stations to provide multiple location control and annunciation so that each station may act independently.

In an emergency protection system having a node which is characterized by one or more detectors for sensing alarm conditions, and a computer means for processing such conditions and generating responses for signalling the occurrence of such conditions to other nodes in the system, the improvement which comprises: (1) A plurality of said nodes, each node being capable of operation independently of the other nodes and each further including: (a) a communication controller having plural data communication lines; (b) means responsive to an alarm condition arising at a given node to instruct the communication controller thereat to send changes in alarm condition status to adjacent nodes; (c) means including said lines for receiving, and replying to, changes in the alarm condition status at adjacent nodes; (d) means for retransmitting from a given node to a first adjacent node a change in the alarm condition status of another adjacent node received at said given node from said another adjacent node; (2) means for separately interconnecting said plural data communication lines of the communication controller of each of said nodes to respective adjacent nodes, whereby changes in the alarm condition status of any one node is communicated to all the other nodes in the system.
