Abstract: A monitoring system includes a host having a plurality of sensor inputs for connection to sensors. A converter is designed to receive input signals from the sensor input and to convert the input signals from the sensors into digital signals. A processing system is configured to receive the digital signals and to generate alarm signals in response to selected ones of the received digital signals. An internally integrated voice/data modem is in operative association with the processing system. A phone connector is placed in operative association with the voice/data modem, to act as a port for transmission of the alarms to an external telephone network. A network connector is in operative association with the processing system and is designed to receive data in the form of alarms from the processing system and to act as a port for transmission of the alarm data to data network.

Abstract: A communications appliance which accepts ASCII character based input and creates fax machine compatible output for transmission over phone lines. The appliance mimics the responses of a modem to provide text-to-fax conversion or provides fax reports based on input from devices not otherwise capable of communicating in the fax mode.

Abstract: A portable, self-contained device for monitoring an area and reporting conditions automatically over standard telephone lines is disclosed. The device communicates through a modem in digital code with digital terminals or in synthetic speech when a digital terminal is not used.

Abstract: A portable, self-contained device for monitoring a selected local area for occurrence of any one of a plurality of preselected conditions, which device comprises a connector, connecting the device to local, standard telephone lines, a sound synthesizer containing selected sound, words and/or phrases at memory addressable locations capable of outputting a sound signal of message indicative of a selected combination of sounds, words and/or phrases, a successive dialing system for dialing successively a repeatable series of preselected telephone numbers in response to an occurrence of one of the monitored conditions, responsive answering to any one of the series of telephone numbers reached by the dialing system to cause the sound synthesizer to place a sound voice message on the telephone lines and dialing termination of the successive dialing system whereby the termination is responsive to a call back to the device.
