inspected a special hazard clean agent suppression system that had gone into trouble status. The control panel was showing a fault in the detection circuit for the server room. Upon inspection, I found a loose wire connection on one of the smoke detectors, likely caused by recent maintenance activity in the ceiling. I secured the connection, reset the panel, and the trouble cleared immediately. I then performed a full system test to ensure all devices and alarms were functioning properly. Informed the site manager of the repair and advised routine visual checks to prevent similar issues.
