Siren FAQ
What is the UH Outdoor Warning Siren System?
The University of Houston Outdoor Warning Siren System is designed to alert persons
on campus of an emergency situation that requires them to seek shelter indoors for
their safety. There are three sirens located on the highest points of campus so that
it can effectively alert persons outdoors throughout the campus.
When is it used?
The UH Outdoor Warning Siren System will only be used when there is an imminent threat
to the lives and safety of people on the UH campus where it is unsafe to be outdoors.
This threat could come in the form of severe weather, an environmental threat such
as a hazardous chemical release, or some other emergency situation.

What should I do if I hear the UH Outdoor Warning Siren System?
When you hear the Outdoor Warning Siren System you should seek shelter immediately.
When seeking shelter, do so by accessing the closest available building in an interior
room that is away from windows. Remain inside until the warning has expired or you
receive the “all clear” notification from emergency personnel and/or via text message. Updates will be available on this UH Alert website.
Why can’t I hear the Outdoor Warning Siren System inside?
The Outdoor Warning Siren System is an outdoor warning system designed only to alert
those who are outside that something dangerous is approaching. For those indoors,
text messages and emails will be distributed as well when the Outdoor Warning Siren
System is activated.
Why don’t the outdoor warning sirens sound an all-clear signal?
The campus community should be indoors awaiting notification from email or text messages.
How can I get alerts when I’m inside?
To ensure you receive emergency email notifications and text messages, please verify
your information in the myUH system (faculty/staff instructions | student instructions). Also, come to this website (UH Alert) for emergency information.
What should I do during a system test?
The monthly test takes place the first Wednesday of the month at 1pm. You should
continue your regular activities during a system test but be cognizant of the tone
for future reference. You do not need to take any special actions during a test.
