A support plate 10 adapted to be fitted to a smoke detector casing 14 provides a means for attachment of one or more unrelated articles 18. The article being clipped, screwed, stuck or otherwise secured to the plate 10. When fitted to a smoke detector casing 14, the unrelated article 18 covers the detector casing, but either leaves a gap to allow air to pass freely to and from the detector or is formed with openings to allow air to pass to the detector. When fitted over a smoke detector, the unrelated article 18 includes an opening 20 through which the detector test button can be reached. The unrelated article 18 typically comprises a hollow housing, the outer surface of which is decorated or adapted to receive a decorative coating. |
