1. An electronic messaging system comprising:
- (a) a plurality of physical units, each comprising;
(i) a microprocessor having a memory associated therewith, (ii) a plurality of visual signaling devices controlled by the microprocessor; and
(iii) a paging receiver responsive to a predetermined RF carrier frequency transmitted by a paging terminal and adapted to receive encoded messages in accordance with a predetermined protocol from said paging terminal, said encoded messages including an address code and whereby only those physical units whose paging receiver is tuned to said predetermined carrier frequency, and having an address matching said address code, can forward the data to said microprocessor for causing the microprocessor to actuate one or more of the visual signaling devices in accordance with the received data for providing notification of a predetermined event.

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.

17. An electronic messaging system comprising:
-
(a) a monitoring center for accepting alerts from authorized agencies;
(b) at least one paging terminal having the ability to broadcast a radio frequency carrier suitably modulated with information including addressing data and message data, said at least one paging terminal adapted to receive paging instructions from said monitoring center pertaining to an alert;
(c) a plurality of physical units, each including (i) a receiver tuned to said carrier frequency, the receiver including a demodulator for recovering the addressing data and message data, (ii) a microprocessor coupled to receive the addressing data and message data, the microprocessor having a memory for storing a code list, and (iii) a plurality of visual signaling devices controlled by the microprocessor, selected ones of the plurality of visual signaling devices being activated only when received addressing data matches an entry in said code list. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)
