ABSTRACT:
A monitor for a plurality of functions associated with a structure such as a livestock confinement structure or the like including detecting fire or intrusion, and monitoring temperature, water supply, ventilation and power supply. The monitor comprises a plurality of sensors mounted at a plurality of locations about the structure adapted for detecting and/or monitoring the above mentioned parameters and providing respective electrical signals corresponding thereto. An electronic circuit is connected with the sensors and includes first indicator circuits connected with the sensors associated with temperature monitoring for producing indication signals in response to variations in the electrical signals therefrom from predetermined ranges of values, and second indicator circuits connected with the remaining sensors for producing indication signals in response to predetermined values of the electrical signals therefrom. Indicators such as visual or audible alarms are connected with the indicator circuits for producing indications in response to the indication signals. In a preferred embodiment, a radio transmitter is connected with the indicator circuits for transmitting the indication signals to a remote radio receiver for receiving the signals and including indicators such as visual and audible alarms.
