ABSTRACT
The intruder alarm system was designed and build in order to let the industrial and commercial company know how important alarm system is all about. These can be of Good help if the intruder will look through this project and support for the development of this project as to let the Federal Government know that the young engineering of today can produce (construct) things that will help the economic and growth in developing this country is technology
The intruder alarm system uses electric component to achieve the alarm sound, these components are integrated circuit (ICI,) Register, capacitors and speaker which when combined together it give an alarm system that can be used in houses, industry and commercial company. And how it can be operated. This project does a long way to give evidence and show that it can be use in the economic in favour of electronics and its usefulness in our present life days. WE suggest that this our project should be looked into by the school administration to see the possibilities of producing this alarm system in a commercial has been made by so doing we will help encourage our nations policy indigenous technology
