Signal and Intercommunication System Trainer: A Technical Study

Abstract

The researcher was motivated to engage in this study to alleviate the pressing problem in the shop which is the scarcity of instructional aids. Many of the technical-vocational institutions in the country today including the Samar State Polytechnic College lack adequate instructional materials. It is economical because this can be made out of local materials and the project utilizes minimal wattage. Safety precautions were then adopted to ensure safety when operating the gadget. These precautions should be emphasized in the development of the effective domain of learning. Together with the safety precautions were the maintenance measures to be followed if the trainer was to last a long time. After the trainer was constructed it was tried for its efficiency. Except for loose connections of binding posts, faulty connection of diode, and humming of the extension speaker, the project was otherwise successful. The study showed that it is feasible to construct a signal and intercom system that can demonstrate low-voltage wiring systems that can perform operations and functions similar to those actual signal and intercom systems installed in hospitals, schools and other office buildings. With this project, the researcher is hopeful that it will contribute to the overall learning process of the student in electricity classes.
