Abstract

An automatic call device for lifts consists of a photo-detector or a passive infra-red detector 1 to generate a potential difference when a person enters its field of action. The device includes a delay unit 2 to prevent premature activation due to accidental interruption of the ray. The output of the delay unit operates a trigger unit 2 such as a monostable multivibrator or Schmitt trigger which controls 3 operation of a lift motor either directly by activating the power supply to the lift motor, or indirectly through a microprocessor. The photodetector may operate by the person breaking a light ray or an infra-red ray or by the person obscuring the ambient light reaching a photosensitive element.
