Abstract
Computerized intrusion detection systems, called the Alarm Monitoring System (AMS), have been in place at multiple Hanford Sites for approximately 10 years. These systems can monitor more than one thousand individual or group data points. The data points are arranged into logical areas called zones. The software for the AMS has the ability to define up to 400 zones. Physical changes to the data points and their locations, buildings, and surrounding areas during the life of the systems make it necessary to update the displays and the maps attached to the systems. The Alarm Display Map (ADM) project is the first of the planned updates. The ADM project provides a costeffective, state-of-the-art enhancement and replacement for the static display colored LED maps and for obsolete display monitor subsystems. It consists of multiple color monitors connected to a single dedicated processor (Apple Macintosh Ilfx, Figure 1). The displays include an aerial photograph overlaid dynamically with pertinent alarm data along with interchangeable displays of sensor status, alarm zones, and building floor-level details. The system combines object-oriented concepts and intrinsic Macintosh system functions to provide a maintenance environment that nonprogrammers may use. The ADM is a stand-alone display subsystem, easily integrated into any other monitoring application by changing map and sensor designations and adjusting the message protocol. The system is programming maintenance free and adaptable as a display subsystem to almost any existing detection system.
