ABSTRACT:
An intelligent alerting and locating communication system includes a centrally located scanner which communicates with a plurality of remotely located receivers to continuously monitor conditions through a plurality of detectors associated with each receiver, including smoke detectors and motion detectors, and through personal radio transmitters. Each detector detects an off-normal state in a monitored condition and makes an indication that is sensed by at least one receiver which stores the occurrence in memory. Each radio frequency transmitter emits a unique coded signal which is received by one or more receivers. If the coded signal is in a valid format, the coded signal is stored in memory. If the coded signal matches a unique code assigned to that receiver, a matched code signal is generated and also stored in memory. The scanner polls each receiver for information stored in memory by sending out unique addresses onto a communication link connecting all receivers, and the appropriate receiver responds to the polling by sending condition information back to the scanner, including any code received from any transmitter so that every receiver which receives a transmitter code communicates that code to the scanner. A controller device is connected to the scanner device which receives address information from the scanner and condition information, including transmitter codes, from each receiver and processes that information and information from a related database to generate a graphical display of condition data, related database data, and location information derived from receiver addresses.
