【Maintenance Work】Emergency Response

The technical ability to unravel the mysteries of broadcasting equipment. Analyzing custom-designed electronic circuits to identify malfunctioning relay components.

We would like to introduce a case where we responded to an urgent request from a high school regarding "the chime not ringing in some classrooms." In addition to an unknown malfunction, the original contractor had already gone out of business, and there was no detailed information about the equipment, making the situation challenging. Our technicians carefully traced each wire in the complex wiring. Eventually, they reached a self-made circuit board installed inside the terminal panel by the previous contractor. By analyzing the custom-designed electronic circuit, they successfully identified the malfunctioning relay component among the multiple layers of wiring. [Case Overview] ■ Issues - The chime does not ring in some classrooms. - The original contractor has gone out of business, and there is no detailed information about the equipment, creating a difficult situation. ■ Results - Successfully identified the malfunctioning relay component by analyzing the custom-designed electronic circuit and tracing through the multiple layers of wiring. - Later, we procured and replaced the alternative relay, restoring normal operation. *For more details, please download the PDF or feel free to contact us.
