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, criminal violence, such as an active shooter on campus, or 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 at the UH Emergency Operations 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, go to the UH Emergency Operations Website for emergency information.

What should I do during a system test?
