Abstract

The present invention provides a remote detection device including a conventional measurement device, such as a thermostat, having an internal contact which is wired in series with a resistor and two wires of a standard telephone line. When the measurement device reaches or surpasses a predetermined set value, such as a predetermined temperature, the measurement device will close the internal contact such that the resistor will short the telephone line. Accordingly, when the ambient condition has reached or surpassed the predetermined set value, the owner or manager of a building will receive a busy signal when dialing a telephone line connected to the remote detection device. In another embodiment the remote detection device may comprise a computer program component which periodically monitors the status of a communication line connected to the measurement device at the remote location.
