<p>PURPOSE:To cope easily with modification of specifications of a human body detection sensor section by making the human body detection sensor section into a unit, then mounting the sensor section dismountably on the body section containing the output signal processing circuit section at the sensor section and electrically connecting the output of the sensor section to the body section through a connector. CONSTITUTION:Housing for a body section 16 containing circuitry except a sensor section 11 is constructed, while being burried in the wall face, with a rectangular box type body 34 having open front face and a cover 35, where the sensor section 11 is fixed to the body section 16 with the front face section thereof projecting from the open section 36 of the cover 35 and secured through a decoration plate 17 to the body section 16. A printed substrate 37 mounting circuitry except the sensor section 11 and the sensor section 11 are connectable through connectors 45a, 45b and the sensor section 11 is fixed dismountably on the body section 16. By such arrangement, specifications of the sensor section 11 can be modified easily.</p> |
