intelligent fire alarm system

computer engineering

The primary purpose of fire alarm system is to provide an early warning of fire so that people can be evacuated & immediate action can be taken to stop or eliminate of the fire effect as soon as possible. Fire is a kind of disaster threatening the social wealth and humanity's safety. Fires usually occur in homes because of carelessness and changes in environmental conditions. They cause threats to the residential community and may result in human death and property damage. In this alarm system alarm can be triggered by using detectors or by manual call point (Remotely). To alert/evacuate the occupants siren are used. Traditional fire detection systems' intellectualized degree is low, the error alarm and the leakage take place frequently. To reduce the rates of alarm error and leakage of the fire alarm system, a fire detection system model and calculating model of fuzzy neural network for processing fire signal are proposed based on the characteristic of fire detection signal and the requirements of fire detection system. The suggested technique in Fire alarm system use the addressable detectors units besides using the wireless connection between the detector in zones as a slave unit and the main control unit as the master unit. The system shall include a control panel, alarm initiating devices, notification appliances, and the accessory equipment necessary for a complete functioning fire alarm system. In the wireless fire alarm, individual units are powered by primary & secondary batteries for the communication.
