Sure thing! When troubleshooting issues with the Fire-Lite FL-PS10 power supply unit, start by checking the input power to ensure it’s within the specified range (typically 120VAC). Next, inspect the connections between the power supply and the panel for any loose or damaged wiring. Additionally, verify that the power supply’s circuit breaker hasn’t tripped. If all connections and power inputs appear normal, it may be necessary to test the power supply output voltage using a multimeter to ensure it’s providing the correct voltage to the fire alarm panel. If you’re still experiencing issues after these checks, it’s advisable to contact a qualified technician for further assistance.
