A smoke detector casing of conventional size and adapted to be secured in any room of a residence or the like, contains not only a smoke detector, an audible alarm and their circuit with a 9 volts alkaline battery as a power supply but also a microprocessor and an automatic telephone dialer and a modem together with a telephone jack for connecting the circuit to a telephone line so as to immediately dial and send a smoke detection signal to a central monitoring station. The circuit of the smoke detector is also used for transmitting emergency signals others than fire alarms. The smoke detector casing also encloses a high sensitivity combined microphone and loud speaker to provide for direct bi-directional voice communication between the occupant of the monitored area and the attendant at the central monitoring station. The direction of the voice communication is controlled by the attendant who can thus manage the panic situation.
