  • Fire detecting apparatus
    Patent number: 5610592
    Abstract: A first dust recovering part is disposed upstream in an air inlet passage from a fire detecting part. The air flow is deflected in the first dust recovering part so as to cause the dust to drop to separate from the air and to be recovered in a recovery area of the first recovering part. Farther downstream from the first dust recovering part, a second dust recovering part is arranged having a filter for recovering dust in the air which has passed through the first dust recovering part. Thus, clogging of the filter is avoided and erroneous operations caused by dust are more reliably reduced. As a result, the reliability of the fire detecting apparatus is improved.

  • Smoke detector having an integral piezo-electric buzzer
    Patent number: 4306229
    Abstract: A fire detector comprises a piezo-electric element attached to a vibrating portion which is part of a component constituting the detector. The component having the vibrating function may be a casing or an electrode or any other suitable member. The piezo-electric buzzer is thus incorporated in the detector to form a simple and compact fire detector with an alarm device.
