Narrative:
We departed msp apr/thu/92 nonstop to hnl. Takeoff weight around 519000 pounds, normal departure. At 17000 ft #1 engine loop B light illuminated. I informed the captain and completed our procedure from our cockpit operation manual. (Normal test on a loop so we continued in a). At FL290 #1 engine gave full fire warning. Captain silenced the bell and directed first officer to fly the aircraft. We performed emergency checklist and returned to msp. Captain instructed me to dump fuel to attain maximum landing weight. System dumped fuel to shutoffs of 11500 pounds (actually around 14000 pounds/tanks 1 and 3, around 50000 #2 tank, and 3000 pounds in auxiliary tank. All xfeeds automatically closed. I completed checklists and secured fuel dump at which time we were on about a 7 mi final to msp. Aircraft was landed at 416000 pounds, 5000 pounds over maximum landing weight. Emergency equipment standing by and normal landing. I would like to have caught the dump process before it shutoff at the 11500 shutoff by closing xfeeds for tanks 1 and 3. I feel I could have got us down to 411000 or less. However, I was very busy with checklists and such. Also, I do not feel the extra 5000 pounds of fuel weight made the operation less safe as the WX was good, plenty of runway, etc. I feel all crew members followed procedures and the result was a safe return to msp.
