Hanford Fire Maintenance was out today after the 2 false alarms at the LSB and determined that the fire alarm control panel is faulty. Apparently a control board has been fried. HFD has taken the panel out of service and will remain disabled until we can correct the problem. Meanwhile, I would ask that the swing and owl shift operators do a walk through of the LSB every 2 hrs for the rest of the week and then 2 hr checks for all 3 shifts on the weekend. Training the control room camera towards the LSB may also be a good idea.
