Human Factors Modifications to a Pre-Existing Alarm System

Among the constraints impinging on enhancement were size and placement of the annunciator tiles. The existing system predetermined the size of alarm tiles, the number of tiles per annunciator matrix, and the placement of the matrices. Window size influenced the possible character density per tile. Character density was viewed with special attention given to readability requirements for the operating station distance. Additional constraints were: to minimize the number of annunciator relocations and to, where appropriate, accommodate pre-existing color and coding schemes.
