Abstract:
A self-contained ambient condition detector comprising:an ambient condition sensor; control electronics coupled to the sensor and responsive thereto, in response to a predetermined ambient condition, a user unalterable, pre-stored, audible, alarm identifying tonal output pattern is emitted wherein the pattern includes a plurality of spaced apart predetermined silent intervals bounded by pluralities of spaced apart tones wherein the tones are interrupted and are spaced apart from one another by silent intertonal spacing intervals of a common duration and wherein the common duration is always shorter than each of the silent intervals and where the control electronics includes voice output circuitry, the voice circuitry includes a factory pre-stored, user unalterable, verbal alarm-type output message, the pre-stored message is associated with the tonal output pattern and verbalizes the respective alarm type and where the control electronics, in response to the predetermined ambient condition, emits the audible tonal pattern and repetitively emits the verbal alarm-type message in respective silent intervals, wherein the voice circuitry includes solid state storage circuitry for the pre-stored verbal message, a second sensor coupled to the control electronics, and a second condition warning audible message stored in the solid state storage circuitry, and a common housing which carries the sensors, the electronics, the output circuitry and a power supply.
