Fire Alarm Response at FBI Building with Access Issues

Summary: Stockton Fire personnel responded to a fire alarm at the FBI building in San Joaquin County, California. Upon arrival, they encountered difficulty accessing the building due to magnetic locks and initially sought a responsible party. After gaining entry, they found a regular alarm sounding. The building was subsequently cleared, the fire alarm was reset, but another alarm (possibly a vault or auxiliary alarm) continued to sound. The situation was resolved without escalation, and the crew reported themselves available for other responses.
