A system and a method in which a sensor interface device receives a sensor signal corresponding to a monitored parameter. A processor is responsive to the sensor signal by storing information relating to the monitored in a memory and by generating a dialing signal when the monitored parameter equals a predetermined value. A transceiver is responsive to the dialing signal by establishing a two-way wireless communications link with a telecommunications network.

[ What is claimed is:] [1.]1. A system comprising:a sensor interface device configured to receive a sensor signal from each of a plurality of sensor controlled devices corresponding to a predetermined condition for each of the sensors;a processor, coupled to the interface, executing an algorithm, programmable from a remote location to actively monitor the different sensor controlled devices and responsive to the sensor signal whereby the algorithm performs at least one operation on the sensor signal and generates an output signal; anda transceiver responsive to the output signal for outputting a control signal for the sensor controlled devices and/or establishing a two-way wireless communications link via a telecommunications network with a selected one of a plurality of remote locations upon an occurrence of the predetermined condition determined according to the algorithm comparing the output signal to a reference value.
