Abstract
Abstract There is provided an elevator shaftway intrusion detector which utilizes a proximity detector including an energy source for generating a detection field within a zone of detection including the elevator shaft-side roof and floor and a corresponding receiver for receiving the detection field when an object enters the detection zone and thereafter generating a detection signal. A power supply and switching network are employed for applying power from the power supply to the proximity detector and which are responsive to the detection signal for applying power from the power supply to a detection indicator such as a siren.
