What to do if AC INPUT FAULT is on for UTC Fire and Security Control Unit?
- W
  William RomeroAug 9, 2025
  If the UTC Fire and Security Control Unit displays an 'AC INPUT FAULT On' message, it indicates a loss or degradation of primary power. First, notify your electric company about the service loss. Then, check the connections to the Power Management Unit (PMU) Board TB1 and use a voltmeter to check for 120/240 Vac at TB1. After that, remove both secondary and primary power, disconnect all field wiring (labeling them first), and ensure the AC Selector Switch is correctly set for your line voltage. Finally, reinstall the board, connect the wiring, and reapply power. Perform functional tests to ensure proper operation.

Why is the BATTERY CHARGER FAULT on in my UTC Fire and Security FenwalNET 8000-ML?
- V
  Veronica RodriguezAug 23, 2025
  If the UTC Fire and Security Control Unit shows a 'BATTERY CHARGER FAULT On' message, it means there’s a failure in the battery-charging circuitry. You should check the battery connections to the Power Management Unit (PMU) Board J10. Disconnect the battery leads from J10 and use a digital volt-ohm meter to measure the battery's open-circuit voltage; replace the batteries if the voltage is less than 22 Vdc. Also, check and replace the fuse on the PMU Board if it's blown. If the problem persists, replace the power supply unit or the Power Management Unit (PMU).
