Abstract
A pager-based alert system includes a monitor center that is in telephonic or data communication with a paging station allowing the command center to send multi-digit code words where selected digits comprise an address for selecting one or more of a plurality of physical units (paging receivers) and to direct the receiver to output visible and/or audible signals indicative of a particular alert condition. By providing the physical unit with graphic icons overlaying the visual indicators, an observer can readily determine the nature of the alert condition so that appropriate remedial action can be taken.
