Abstract

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.
