It’s easy to understand why fire alarm systems are inherently the right choice for use in mass notification systems. Fire alarm systems are code-driven and regulated. The circuitry is fully supervised, and the systems are periodically tested using NFPA guidelines. The rules, testing procedures and installation practices are already established, so fire alarm companies are able to hit the road running. Also, the first responders are already familiar with the fire alarm equipment, many with years of hands-on experience. Many of the technologies designed to address our nation’s homeland security needs are still in development. But fortunately, this is not the case with mass notification systems and emergency evacuation systems. Mass notification systems have arrived – spread the word.
