WIRELESS COMMUNITY ALERTING SYSTEM

摘要

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 receiv er to output visible and/or audible signals indicative of a particular alert condition. B y 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.
