Earthquakes pose significant threats, especially in vulnerable regions like the Philippines. Seismic detection alarms are restricted in orchestrating an evacuation plan for multi-story structures resulting in the disorganization of the evacuees. To address the issue, the researcher introduced LumineSENSE, a device for detecting ground movements with real-time alerts of coordinated flashing lights for occupants. Increasing alert durations were given from the ground floor to the highest floor providing occupants ample time to leave the room orderly. The researcher conducted three tests for functionality and a field test to affirm the device’s reliability. The accelerometer was tested to affirm that it can input x, y, and z displacements enabling it to satisfy a code condition that will activate the LED lights with buzzer, and LED pins; each set with a corresponding duration relative to the floor level. In testing the individual components, the device is certified to be functional with the integration of the hardware constituents. The researcher then conducted a field test to observe the significant difference in evacuation duration with LumineSENSE and the optimal evacuation time without the device; time recorded starting from light stabilization until the occupants evacuated the floor. As the critical t-value (0.31) falls outside rejection regions (±4.303), the null hypothesis is not rejected; thus, there is no significant difference between the duration of evacuation with LumineSENSE to the optimal time based on standard evacuation procedures. Test results affirmed the device’s potency as an earthquake alert system, ensuring well-coordinated evacuations in multi-story buildings.
