Miracle One Electromechanical Linear Gate Operator Linear mechanical, 24 volt DC gate operator. It uses a precise limit switch system that reduces stress and creates a consistantly smooth operation.   The Miracle-one™ is one of the first linear mechanical, 24 volt DC gate operators that offers all the features the consumer demands. One of these features is variable speed, which is electronically controlled by a micro controller and precise limit switch system. The gate operator starts the cycle slowly, increases in speed, then comes to a stop slowly with the use of internal limit switches. This reduces stress and creates consistently smooth operation. Battery backup is included to provide fully functional operation for 100-200 cycles in case of power failure. Also included are a 2 way reversing sensor and a vandalism/burglar alarm indicator. The Miracle One&tm; is ultra quiet, has a weatherproof housing, and features an Emergency Release Key. The state of the art features offered in the Miracle-One™ make it one of the most advanced operators in the world and will create new standards in the gate operator industry.   MECHANICAL SPECIFICATIONS Alarm included Approval UL and ETL listed to the latest UL325 and UL991 specifications.
