More Information
Summary:A theft alarm system for warning of unauthorized use of a bicycle or similar movable article employs a pendulum switch to sense movement of the article. The switch actuates a warning alarm, which continues for a brief period upon each sensed movement. The device clamps to the protected article, and a padlock passed through an opening in the clamping member prevents loosening or removal of the device. A disarm switch to deactivate the device includes a moving arm which must traverse the padlock opening, preventing disarming of the system unless the padlock is first removed.
