Abstract
A system for detecting fires in a barn or similar structure includes rate of rise heat detectors and temperature sensing cable. Upon detection of a predetermined rate of rise or a predetermined temperature the control circuitry of the system produces an output signal that activates an audible alarm mounted outside the barn. The control circuitry also produces an FM signal that travels through the power lines servicing the farm. The FM signal activates an audible alarm plugged into an electrical outlet in the home.
