A smoke detector (50) includes a housing defining a dark chamber (24) admitting test atmosphere. A light receiver is disposed within the chamber. A scatter emitter (32) is positioned within the chamber such that light strikes the receiver (28) when reflected off particles suspended in the test atmosphere. An obscuration emitter (38) is positioned within the chamber such that light emitted is directed to the receiver (28) unless obstructed by particles suspended in the test atmosphere. |
