Описание к видео Notifier System at Stone hill Middle School

there's a fire alarm inspection going on at the school so I pulled a bunch of pull stations on this video test a couple of smoke detectors as well along with the fire technicians so the pull stations are seen as the notifier npg-12 lx's along with system sensor L series and system sensor specter alert advances the same system at the other school so hopefully you guys will enjoy this video and please sit back relax and enjoy
