MUNICATION SYSTEM
ABSTRACT
An munication system that is capable of broadcasting a live message to a specific zone of a protected structure, recording the live transmission, and repeating the recorded message to the same protected zone. In certain embodiments configured to protect multiple zones, the system further permits broadcast of a second live message to another zone of the structure, recording the second live broadcast, and repeating the second recorded message in the same zone to which the message was broadcast live. The system includes hardware such as a processing element and speaker assemblies and puter program for instructing the processing element to carry out the transmission, recording, and re-broadcasting of messages through the speaker assemblies.
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention is generally directed toward an munication system that may be installed within a protected area of a protected premises, such as a multi-level building, a sprawling single level building, or multi-building campus. The munication system permits system operators to broadcast live messages to individual zones within the protected area, record the live messages while they are being broadcast, and then automatically replay the recorded messages. Thus, the system eliminates the need for a system operator to continuously broadcast the same live message to particular zones of the protected area.
[0003] 2. Description of the Prior Art
[0004] It is mon for mercial or public buildings to possess some type of alarm system capable of notifying occupants of a potentially dangerous situation, such as a fire. In the past, such systems upon actuation emitted a siren, bell, or other type of alarm that alerted building occupants to evacuate the structure. Typically, actuation of the alarm indicated the presence of a fire in the building. How
