Programmable logic control (PLC)-based fire alarm system

Abstract

The main goal of the study was to assemble a PLC-Based Fire Alarm System and to find its performance in the aspect of smoke and heat detection and its effect to the automatic alarm and automatic sprinkling by using a Programmable Logic Controller (PLC). The study was conducted at Bohol Island State University-Main Campus, Tagbilaran City, Bohol in the Academic Year 2016 - 2017. The study utilized the experimental design of research. The researcher has chosen twenty (20) electrical and electronics instructors to validate the performance of the device and ten (10) experts from other learning institutions and private industries in the Province of Bohol to assess the acceptability of the device. Upon the assembly, various trial-and-errors conducted until the device was 100% functional. The performance of the device was rated through an observation guide. A self-made questionnaire was given to the respondents to find the acceptability level of the PLC-Based Fire Alarm System. The researcher gathered all the data, analyzed and interpreted the result. Based on the results of the study, the level of performance of the device got a general rating of 3.54 which described as “Very Good” and was found out to be highly acceptable to the respondents. This means that using PLC as the main controller in a fire alarm system was highly acceptable. The PLC-Based Fire Alarm system will be used to provide notification in case a fire emergency will occur in a building.
