Abstract
A public addressing and emergency system has a person or message signal generator for generating a message whose contents comprise at least one of a sign language message, a voice message, and a text message and a transmitting system for transmitting the message signal to at least one of a mobile unit and at least one fixed display unit in at least one location. The message signal transmitting system is bi-directional enabling bi-directional message communication and may include a device such as a splitter for generating multiple signals and/or a device such as a booster for increasing or maintaining the power of the signals. The public addressing system can be independent, or tied in with internal processing of commercial entities and their electronic displays to present advertising and educating the public about the emergency system.
