It’s possible that there could be various reasons for the alarm on your Fire-Lite MS-4 panel without the presence of fire or smoke. Firstly, check if there are any trouble indicators or system faults displayed on the panel. These could indicate issues with power supply, communication lines, or sensor malfunctions. Next, inspect the system’s wiring and connections to ensure there are no loose or damaged wires. Additionally, consider any recent changes or upgrades to the system that might have inadvertently triggered the alarm. If you’re unable to identify the issue, it’s recommended to contact a certified technician to perform a thorough inspection and diagnostics of your Fire-Lite MS-4 panel.
