Mass Notification System FAQ

An outdoor warning system was installed at Trinity University in July 2013. The system uses a siren followed with a message to alert the campus community to take shelter in the event of an emergency. The University plans to test the system once a month. The University is dedicated to ensuring everyone knows what to do when they hear the siren and message.

When are the sirens tested?

The system test takes place at approximately 11:50 a.m. on the first Wednesday of every month. The tests last approximately one minute. You do not need to take any action during the test. If a severe weather warning is issued for the area on a scheduled test day, the test will be cancelled for that month.

What should I do during a system test?

You should continue your regular activities during a system test. You do not need to take any special actions during a test.

How can I tell the difference between a monthly test and an emergency?

Monthly tests will begin with the announcement, "This is a test." If you hear the sirens, and do not hear, "This is a test," this means there is an emergency. A system test will only take place at approximately 11:50 a.m. on the first Wednesday of the month, and will never last longer than a minute. In the event of an emergency the siren and message will sound until the emergency is over, at which point you will hear an "all clear" announcement.

What should I do when I hear the siren and message?

When you hear the siren and message you should follow the instructions given.

What types of emergencies do the sirens indicate?

The sirens indicate emergencies that make it unsafe to be outdoors and require you to seek immediate shelter. The most likely cause of these unsafe outdoor conditions is severe weather, but other causes may include the unlikely occurrences of an environmental hazard or an armed individual on campus. The siren and message are only used for emergencies that impact or present a danger to our campus. For example, the siren and message will not be sounded for a tornado watch in the Bexar County area, but they will be sounded if there is a tornado on the ground that has the campus in its forecast path.

Where are the speakers located?

The Mass Notification speakers are located on top of two buildings on the Trinity campus. The speaker arrays are located on the roofs of Center for the Sciences and Innovation and the Thomas Residence Hall.

Where can I hear the sirens?

The sirens are loudest within the main campus. They are audible on both upper and lower campus, and are designed to be heard outdoors. You may not be able to hear the sirens if you are indoors or are listening to music using ear phones. In the diagram below, the green border represents the area in which the sirens are loudest.
