[ I claim:] [19.] A single dwelling alarm system comprising at least two independent hazardous condition detectors provided in separate locations within a dwelling, in which each detector provides its own local first alarm and transmits a coded rf signal having a predetermined code when a hazardous condition is detected locally and further provides a local second alarm when a coded rf signal having said predetermined code is received from another like detector at a remote location, and wherein each detector comprises:means for sensing a local predefined hazardous condition and responsively providing a hazard signal when such a local hazardous condition is sensed;means for transmitting a coded rf signal having said predetermined code upon the occurrence of a hazard signal being provided by said sensing means;means for receiving a coded rf signal having said predetermined code transmitted from another like detector at a remote location; andmeans responsive to said sensing means and to said receiving means for providing respectively corresponding and humanly detectable and distinguishable audible alarm indications that a hazardous condition is sensed either locally or at a remote location.
