Quick answer
A fault light means part of your fire alarm may not work in a fire. Common faults are a flat standby battery, a broken cable (open circuit), an earth fault, a missing detector or a sounder circuit problem. Note exactly what the panel says, check mains power and batteries, and get a technician quickly: until it's fixed, part of the building may be unprotected.
