Emergency Horns and Sirens




EMERGENCY HORNS & SIRENS

JMU currently utilizes two different systems that produce audible signals to warn students, staff, and visitors on campus of impending emergency situations or hazardous conditions.

One component of the University's Emergency Communications System is Madison ALERT Horn, Siren and Public Address system that can be activated to alert members of the University Community of an imminent threat to public safety on campus. The following Horns and Sirens are used as part of this system.

EMERGENCY SIREN: WAV - MP3
This signal is intended to immediately get the attention of members of the JMU Community. When students, staff and visitors hear this siren they should immediately try to seek shelter in a secure location and following any verbal instructions that accompany this alarm.

ALL CLEAR HORN: WAV - MP3
This signal consists of three consecutive 5 second horn blasts and indicates that it is now safe to resume normal activities on campus.

A second component of the University's Emergency Communications System is the JMU Severe Weather Early Warning System. This separate system is completely automated and continuously monitors weather conditions in proximity to the University's Main Campus and Memorial Hall Complexes. When the system detects atmospheric conditions that have a high probability of producing an electrical storm (lightning) close to campus the system will activate a series of horns and strobe lights in designated areas on campus. The following Horns are used as part of this system.

RED ALERT HORN: WAV - MP3
This signal consists of a single 15 second horn blast and indicates that there is an imminent danger of a lightning strike on campus. When students, staff and visitors hear this horn they should immediately try to seek shelter in a safe location such as a building or vehicle away from water and electrical sources until the severe weather passes and the All Clear signal is given.

ALL CLEAR HORN: WAV - MP3
This signal consists of three consecutive 5 second horn blasts and indicates that it is now safe to resume normal activities on campus
