An addressable fire alarm system provides the user with the status of the initiating devices that comprise the system network; that is, smoke detectors, water flow switches, etc. The fire alarm system control unit allows the user to easily view the system status and features information about the emergency device as well as detailed information about the device's "address." The system hardware or software can also assign digital addresses for each device. The location of an operated addressable device is communicated via annunciation, printout, or other communication, and is also visibly indicated according to building, floor fire zone, or other approved subdivision.

An analog addressable system has all the characteristics and features of an addressable system, but expands on the information provided to the control panel. Detectors in an analog addressable system become "sensors" that relay information to the control panel regarding how much smoke or heat the detector is sensing. The control panel is then able to make action decisions based on this higher level of information, including when or when not to go into alarm mode.
