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.
The building manager reported low pressure in one of the zones. After inspecting the riser room, I found that the main control valve was partially closed, restricting water flow. I verified this by comparing gauge readings and tracing the piping for any obstructions or leaks—none were found. Once I fully opened the valve, the pressure normalized across the system. I conducted a flow test to confirm proper operation and notified the building manager that the system is now functioning as intended.
The control panel showed trouble signals from Zone 3, tied to the storage mezzanine. After inspecting the devices, I found a smoke detector near an HVAC vent that was blowing dust directly into it, causing the false alarms. I powered down the zone, cleaned the detector, and coordinated with the HVAC tech to adjust airflow. After reactivating the system, I ran a full test—everything is now functioning properly.
