Abstract:
Fire alarm system plays an important role in maintaining and monitoring the safe of
all kind environments and situations. However the usability of many existing fire
alarm system is well known but could be produce with high cost. Subsequently, it is
not affordable for the low income users. The main objective of this project is to make
a fire control system with low cost. The project has three main systems, 1) the
detection system, 2) the monitoring system and 3) the appliance system. The detection
system operates as the fire detector. This detection system has components like flame
detector, smoke detector, light detector, heat detector etc. This paper discusses the
design and implementation of a fire alarm system using the microcontroller which
operates the entire system. The detectors are placed in parallel in different levels. Any
signal from each detector at any level is monitored using monitoring system. The
appliance system has components like buzzer for alarming and motor pump to stop
the fire. The entire system is controlled by microcontroller. The microcontroller is
programmed in such way by using C-Programming. From the project done, the
system can detects smoke, light, flame, heat etc. sensed by the detector, followed by
the monitoring system which indicates smoke, light, flame, heat etc. at that particular
level. Finally when the sensors form each level triggered individually, the main
buzzer operates and disconnect the AC power supply. Then it shows in the control
panel LCD display which area is affected and which is safe. Then it runs the
emergency exit motor to escape and the water pump motor to the affected zone to stop
the fire.
