Halma has been granted a patent for a smoke or fire detector designed for ceiling mounting. The detector consists of three parts: a mounting part, a detector housing part, and a cover part. The housing part includes a top plate with a recess, electrical connections above the recess, drains on the surface of the recess, and conduits extending downwards from the drains. The cover part has exhaust ports on its bottom surface to vent condensation and airflow, and an opening for smoke or gas ingress. The design effectively directs condensation away from electrical connections and ensures proper airflow.

Patent granted for a ceiling-mounted smoke or fire detector
A recently granted patent (Publication Number: US11749082B2) describes a smoke or fire detector designed for ceiling mounting. The detector consists of three parts: a first part for mounting on the ceiling, a second part that houses the smoke or fire detecting means, and a third part that covers the lower surface of the second part.
The second part of the detector includes a top plate with a recess, at least one electrical connection above the recess, at least one drain through the surface of the recess, and at least one conduit extending downwards from the drain. The third part features at least one exhaust port on its bottom surface, which receives the conduit to provide venting for condensation and airflow below the third part. The exhaust port is positioned radially inward from and below the opening for smoke or gas ingress, ensuring that condensation and airflow are directed away from the opening.
The patent also mentions various additional features and configurations. For example, the recess in the top plate can be annular in shape. The first part of the detector has electrical connections that make substantial contact with the electrical connections in the second part when they are assembled. Plastic interlocking elements can be used to hold the first and second parts together. The second part may have multiple conduits, and these conduits can protrude beyond the bottom surface of the third part. When installed in a ceiling, the conduits provide a route for air from above to vent out below the lower covering part, bypassing the detector.
In summary, this patent describes a ceiling-mounted smoke or fire detector with a unique design that allows for efficient venting of condensation and airflow. The detector's three-part structure and specific arrangement of components ensure that the electrical connections and openings for smoke or gas ingress are protected from condensation and airflow. The patent also mentions various optional features and configurations that can be incorporated into the detector design.
