A diverse college campus is comprised of many outdoor and indoor areas that require a way to warn students, faculty and visitors. The most effective way to do this is to issue a warning tone, followed with a clear, powerful voice message, ALERT and then INFORM. You need more than just a campus siren.


Whelen Engineering's two-step approach for a Mass Notification System is, ALERT and INFORM, eliminates confusion, restores order and ultimately saves lives. Tone-only sirens fail to inform. The diverse populace of a college campus will not know what to do without the ability to inform.


Whelen Engineering's pre-recorded voice message capability is unmatched. Distortion-free voice messages, pre-recorded at the factory in studio like conditions, optimized for power and clarity.


Voice messages as well as musical renditions of various lengths can be recorded in digitally formatted audio for crystal clear reproduction and intelligibility. Digital voice recordings in multiple languages.


Instant communication with portions of the campus or all-campus alerting, indoors and out.


Live public address. Deliver critical communication specific to the event with the use of a microphone at the emergency operations center.


Every campus is different. A campus alert warning system can be customized to meet your needs.


Whelen Engineering's and Mid-State's approach to warning the public is serious business. We will not compromise on quality. Unlike any other campus alert system manufacturer, Whelen Engineering's products are designed, preassembled, pre-wired and tested at their facility to ensure product quality and reliability.
