The Importance of Redundancy in Emergency Notification Systems

A student is called to the office but the PA system disrupts the entire school to make the announcement. A student has a medical emergency in a hallway but there’s no way to communicate with nearby classrooms. Instructions for fire, lockdown and tornado drills aren’t clear or specific to each area of a building.

No single emergency notification system can cover every scenario and communicate in every way possible, as explained in a recent survey and report by Campus Safety: “… several mass notification systems should be deployed so that the weaknesses of one solution can be compensated for by other so­lutions.” In fact, most K-12 and higher ed survey respondents use multiple systems to ensure that emergency communication is clear, redundant and reliable.
