Mass notification systems are typically provided in educational or campus-style environments and are used to notify a large population of an event (the owner decides what events are broadcast) that requires their attention in a short time. Mass notification can be installed for music and entertainment or for reporting events such as weather warnings (tornados, snow, flood, etc) or locked-down buildings. IFSS represents a variety of reputable manufacturers of sound systems that include Notifier, Talk Phone, Cooper Wheelock, Carehawk USA, Dukane, Atlas Sound and IED.
