Stanford AlertSU annual testing

October 17, 2017

On Thursday, October 19, between noon-12:30 pm, Stanford University will conduct its annual test of the campus AlertSU system. Alert messages will be sent via text message and email to the Stanford community.

The test will also include activation of the outdoor warning system, which will sound an audible tone for approximately 60 seconds followed by a verbal message from each of the 7 sirens at various campus locations. The sirens will be audible throughout the campus and may also be heard in parts of the surrounding communities including Palo Alto, Menlo Park and Los Altos.

Also being tested is Cisco VoIP speaker phones.  VoIP speaker phones are found in many of the academic and office buildings throughout campus. If you have a Cisco phone in your area, the alertsu message will broadcast from the speaker phone and a banner message will appear in the display.

If this were a real emergency, you would be asked to follow the specific instructions in the alert message. Other avenues, which might be used to inform the community about critical incidents, include:

Upon receipt of an AlertSU message, notify others in your immediate vicinity to ensure they are also aware of the situation and the recommended safety precautions.

Evacuation procedures and how to respond to other emergencies can be found in the Safety, Security, and Fire Report 2017 and the Stanford University Emergency Response Guidelines.

Thank you for your cooperation.
