Hi there! Troubleshooting wiring or connection issues with the Fire-Lite MS-2-L8 panel typically involves a systematic approach. Firstly, ensure that all power sources are connected and functioning properly. Check for any loose connections or damaged wires both at the panel and at the devices (sensors, detectors, etc.) connected to it. Next, utilize a multimeter to test for continuity along the wiring paths, starting from the panel and moving outward to each device. Look out for any unexpected breaks or discrepancies in the readings. Additionally, verify that the correct wire types and gauges are used according to the panel’s specifications. If everything appears intact physically, consider resetting the panel and reprogramming any settings that may have been altered. If the issue persists, it might be wise to consult a certified technician for further assistance. Remember, safety should always come first when working with electrical systems.
