During the recent year of Information Technology, the present focus is on creation and also dispersion of information. In purpose to reach the end users for the provision of information, the popular technologies currently being used include telephone wires, fiber optic, wireless and satellite technologies. However each has its limitations of cost and availability to reach the maximum number of users. In this paper, I proposed that power line carrier is used as medium instead of traditional transmission mediums for carrying the information from sender to the receiver. Based on the proposed method, i designed Fire Alarm System based Power Line Carrier (PLC) using DSB-FC modulation and which is a prototype that enables to transmit signal from located sensor using existing power distribution line cable to give warning for possible fire hazards to local residents. Before transmit the signal over a PLC, modulate the signal using amplitude modulation technique and transmitted.
