1. A surface mountable smoke detector comprising:
- a housing which bounds, at least in part, an internal volume and which has a mounting side positionable adjacent a mounting surface;
at least one smoke sensor carried within the housing and located adjacent to the mounting side wherein the housing is open, in part, to provide substantially symmetrical in-flow and out-flow of ambient atmosphere adjacent the mounting surface to and from the sensor.

Abstract
A smoke detector has a geometry that locates a sensor or sensors at or near a boundary layer of smoke movement thus facilitating smoke entry into the sensor and/or sensors. The sensors are mounted so as to protrude from the bottom of a cover instead of into the cover of the detector.

20. A detector comprising:
-
a housing which defines an internal region wherein the housing has a mounting section with an exterior surface and an interior surface and wherein the housing has at least one region, adjacent to the interior surface, for atmospheric ingress and egress with a substantially planar flow path through the housing adjacent to the interior surface; and
an ambient condition sensor having an atmospheric input/output region wherein the sensor is carried within the housing with the input/output region, at least in part, extending into the planar flow path. - View Dependent Claims (21, 22, 23, 24, 25)

26. An ambient condition detector comprising:
-
a substantially planar support element for conducting electrical signals wherein the element includes first and second spaced apart mounting surfaces;
a first sensor carried on a first surface of the element; and
an audible output device carried on a second surface of the element which includes a housing which defines a substantially enclosed internal region with a perforated section so as to permit an inflow and outflow of ambient atmosphere wherein the planar support element is carried by the housing in the region oriented with a selected end region of the sensor extending toward the perforated section and with the audible output device extending away from the perforated section. - View Dependent Claims (27, 28, 29)

30. A surface mountable smoke detector comprising:
-
a housing which bounds, at least in part, an internal volume and which has a mounting wall;
at least one smoke sensor carried within the housing with a sensing region located adjacent to the mounting wall wherein the housing is open, in part, adjacent to the mounting wall to provide substantially symmetrical in-flow and out-flow of ambient atmosphere to and from the sensing region of the sensor; and
an alarm indicating output transducer carried within the housing displaced from the inflow and outflow.
