De Anza Alert: A building is being evacuated due to a fire alarm. Please exit the building immediately and move to a safe distance. Await further instructions before re-entering.

This text has been reconstructed from news coverage and may not reflect the exact original wording.

Reconstructed from news coverage of the evacuation; no archived verbatim copy of the De Anza notice was located, so it is marked unconfirmed.
This is a routine alarm-driven evacuation rather than a confirmed fire, the kind of low-severity incident that rarely makes the archive but reflects everyday campus-alert practice.
The Santa Clara County Fire Department, not campus police, was the authority confirming no smoke or fire.
Context

Background

De Anza College, a large community college in Cupertino, California, in the Foothill–De Anza district, evacuated a building on October 3, 2022, after a fire alarm activated, according to the Santa Clara County Fire Department via KRON4. No smoke or fire was visible, and the building was cleared purely as a precaution. Once the alarm system was operational again, occupants were allowed to return. The college maintains a public campus alerts page and runs active-assailant and evacuation training through its emergency-preparedness office. This routine, low-severity incident contrasts with the bomb-plot evacuation that struck De Anza decades earlier and shows the everyday end of the campus-alert spectrum at community colleges.

The case documents a routine, low-severity alert type underrepresented in an archive dominated by violent incidents
Outcome
No smoke or fire was found. The building was evacuated as a precaution and reoccupied after the alarm system was reset.
