The control unit powers the fire alarm system. It transmits signals from pull boxes and fire detectors to the alarm signal devices, either audible or visual, installed at strategic locations in the building. Audible signal devices include bells, speakers, and sirens, a strobe light being a common visual signal device.

Mass notification systems (MNS) are used to provide real-time descriptive information and directions to people during fire and nonfire emergencies. For example, many fire alarm systems have a paging system to notify building occupants of a fire situation en masse. Mass notification systems cover not only buildings, but campuses, cities, regions ...
