  Main Control Room experienced a brief alarm for LNDS zone C at 23:37 on on 11/13/13.

Andy Stevens notified MCR that the alarm likely occured due to AirGas refilling a dewar, which caused C-D Interconnect LNDS valve to open
for less than a minute. Andy advised that users in SR sectors 27-35 monitor their nitrogen cooled equipment for any abnormal behavior
and report anything unusual.
