Abstract

A wireless detection system for monitoring a predetermined area for an emergency situation. The wireless smoke detection system includes a plurality of detector units strategically positioned throughout the monitored area. Each of the plurality of detector units include a detector for sensing one of a characteristic and condition within a section of the monitored area and generating a signal indicative of the monitored. A signal processor is connected within each detector unit for analyzing the signal generated by the detector and upon determining if the signal is above a predetermined level generating an emergency signal. A transmitter is provided for transmitting the emergency signal to a plurality of receiver units strategically positioned about the monitoring area. Each receiver unit includes an alarm for generating an alarm signal and thereby alert persons to the emergency situation at a position within the monitored area. The detector can be at least one of a photoelectric smoke detector, an ionization type detector, a combination carbon monoxide and smoke detector, a carbon monoxide detector, a near infrared detector and a hazard detector.

Claims

1. A wireless detection system monitoring a predetermined area for an emergency situation, said wireless detect on system, comprising a plurality_of detector units and a plurality of receiver units strategically positioned throughout the monitored area, each of said detector units comprising:

a) means for detecting one of a characterstic and condition within a section of the monitored area and generating a signal indcative of the monitored conditionl;

b) signal processing means for analying said signal generated by said detecting means and upon determining if the signal is above a predetermined levele generating an emergency signal;

c) means for transmitting wirelessly said emergency signal including means for delaying transmission of the signal; and

d) means for generating an alarm signal upon receipt of said emergency signal from said signal processing means, said alarm signal alerting persons of an emergency situation at a position within the monitored area; and

each of said plurality of receiver units includes;

a) a housing containing means for receiving said emergency signal generated by any of said plurality of detector units;

b) said housing also containing means connected said receiving means for generating an alarm signal upon receipt of said emergency signal; and

c) said housing having means for plugging into a standard electrical outlet for receiving electrical power, a power indicator light to indicate that electrical power is being supplied to said receiver unit, and a stabilizing foot extending from a base of said housing for positioning the housing flush against a wall whereby said receivers may be moved and located where most convenient for alerting people of any emergency situation;

e) each of said detectors further includes means for encoding said emergency signal prior to transmission by said transmission means and each of said receivers further include means for amplifying and decoding said emergency signal upon receipt by said receiving means;

f) wherein each of said plurality of detectors is one of a near infrared smoke detector, a photoelectric smoke detector, an ionization type detector, a combination carbon monoxide and smoke detector, a carbon monoxide detector and a hazard detector.
