Abstract
Fire incidents in industrial and commercial facilities demand fast, reliable detection across multiple zones. A PLC-based multi-channel fire detection system provides structured monitoring, clear zone identification and programmable response logic suitable for academic and demonstration use.
This project integrates a programmable logic controller with smoke, temperature and/or flame sensors on several input channels. Ladder logic evaluates sensor states, latches alarms, drives zone LEDs or lamps, activates a buzzer/siren and can energise relay outputs for external devices. The design emphasises industrial wiring practices, I/O mapping and safety-oriented programming.
It is an excellent final-year project for students in Mechatronics, Electrical & Electronics, Instrumentation, Industrial Automation and related disciplines.
