Abstract: A smoke alarm network for buildings and the like comprises a plurality of stations having a smoke detector alarm unit installed in each. Station switching members are connected at each station, and a central control panel is provided with switching members connected with each of the stations and responsive to identifiably indicate alarm signals sent by the station detectors to the control panel. An alert switch is mounted on the control panel and is operably connected with each detector-alarm unit for selectively activating the alarm positioned at one or more of the stations.
