CY 2021 is now upon us, and this is a chance to refresh the conversation regarding Public Safety, in the domain of mass notification and response systems and support. First and foremost, we recognize that myriads of electronic and aural systems are now present in the topology of Public Safety and emergency and routine notification systems. However, as anyone that knows our practice at FSPS, it’s really all about the desired “response” being activated or informed. This conversation will focus on the who, what, where and how a large amount of overlapping applications, sirens, and PA systems can be applied for the one goal: save and protect lives.
