Abstract: DAYAUON, HENRY CARL R., DIMAS, LOVELY MAE P., and ROMAN, JERRIE MAE Y. Design and Development of an Intercom System for the College of Engineering and Information Technology. Undergraduate Design Project. Bachelor of Science in Electronics and Communications Engineering. Cavite State University, Indang, Cavite. April 2008. Adviser: Engr. Cesar C. Carriaga. The design and development of an Intercom System was conducted at Golden City Subdivision Anabu II-F, Imus, Cavite. The main objective of the study was to design and develop an intercom system for the College of Engineering and Information Technology of the Cavite State University. The project was composed of ten telephone units and an intercom device that acts as the controller for the whole system. The ten telephone units were installed to the ten offices of the College of Engineering and Information Technology. The controller was placed in the Department of Agriculture and Food Engineering (DAFE). The intercom device was composed of a power supply, relays and a microcontroller. The power supply used two step down transformers that transformed the 220V AC to 100V, 50V, 12V and 5V required for the ringer, telephone unit, relays and ICs, respectively. The relays act as the switching device whenever a call was made. The PIC microcontroller controls what tone is heard when the phone is used. The total cost of the device was PhP 17, 310.00.
