General Description

Delivering the right message – to the right people at the right time, is paramount to life safety. From catastrophic natural disasters to terror threats, places like schools, college campuses, malls and industrial facilities face multi-layered emergency communications needs.

The 400 Series MNS LED displays provide critical alerts and programmed messages automatically via highly visible, full color LED signage as soon as an emergency event is triggered, thus ensuring that all students, faculty or employees are aware of the crisis and know how to proceed to safety.
