During the recent years, we focused on creation and also dispersion of information. In purpose to reach the end users for the provision of information, different types of technologies currently being used include telephone wires, fiber optic, wireless and satellite technologies. But each has its limitations of cost and availability to reach the maximum number of users and also major considerable parameters in a communication system are transmitting power and bandwidth. Hence, it is very much necessary to save the power and bandwidth in a communication system. In this paper, we 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, we designed a Fire Alarm System based on Power Line Carrier (PLC) using DSB-SC modulation rather than 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 double side band with suppressed carrier amplitude modulation technique and transmitted.
