Abstract:
1. An ambient condition detector comprising: first and second, ambient condition sensors; control electronics coupled to the sensors wherein the electronics emits at least two, different, unalterable pre-established alarm indicating tonal, output patterns wherein each pattern includes predetermined silent intervals and each is associated with a respective one of the sensors; voice output circuitry, coupled to the electronics, wherein the voice circuitry can output at least two different user unalterable, verbal alarm output messages wherein each of the messages is associated with a respective one of the tonal output patterns and verbalizes the respective alarm type and wherein the control electronics, in response to a detected alarm condition, outputs an audio representation of a respective one of the tonal patterns and an interleaved respective verbal alarm type message in a respective silent interval; wherein each tonal output pattern defines groups of substantially identical output tones with constant intragroup spacing of a first amount and constant intergroup spacing of a second amount wherein the second amount is at least two times greater than the first amount; and a common housing for the sensors, the electronics and the output circuitry.
