Based on the 2013 NFPA 72®, the new Notification Appliances Online Course covers both audible and visible notification appliances. Audible and visible notification can be used to trigger the desired occupant behavior, so the success of every system depends on their correct application. Course 3 in the NFPA 72 Online Course Series — Notification Appliances — covers appliances that are used to alert and inform building occupants and fire alarm system users. Along the way, you will learn some special terminology used for audible signaling and for visible signaling. When discussing audible and visible signaling, the lessons will cover requirements for both public mode and for private mode notification. This course will also provide an overview of other types of notification appliances that you might use in special applications.
