SafeAlert: Emergency Alarm System is an affordable and practical safety innovation designed to overcome the high cost of conventional alarm systems in homes, schools, and public buildings. Built using simple electrical components costing only RM63.00, the system uses a parallel circuit to activate both a warning light and siren simultaneously, ensuring reliable visual and auditory emergency alerts. Testing in home and school settings confirmed its effectiveness and practical use. SafeAlert improves emergency preparedness, safety awareness, and accessibility for budget-constrained users. Its simple design, scalability, and future development potential support commercialization and align with Sustainable Development Goal 9 (SDG 9).
