This study aimed to innovate the Anti-burglary Security System using GSM Module 900a. Specifically, this study sought to: design, construct and assemble the device and evaluate it in terms of: Level of technical soundness; level of technical performance; and level of social acceptability. Through project development and descriptive-evaluative research design, findings of the study showed that the ABBS and its operational manual were developed for viable use. The ABBS was an efficient device because of its very highly performing and very highly functional rating.viii, 53 p.: ill.
