Abstract

The system controls the dispensing of beverages in a bar. The system has individual manually actuated beverage dispensers equipped with electrically controlled flow valve devices which meter and dispense variable amounts of beverages upon command by a user. The system is provided with a key pad offering a selection of beverage mixes. A control device is connected to the beverage dispensers and the key pad for recording use of the beverage dispensers by the user, and for causing the flow valve devices of the dispensers used to make up a beverage mix selected on the key pad to dispense the amounts of beverage prescribed for the selected beverage mix. The controller provides for a controlled use of the beverage dispensers for preparing a beverage mix selected on the key pad in addition to a direct manual use of the beverage dispensers by the user. An anti-tamper circuit for use with coded electromagnetic valve bottle stoppers is also included in the system to detect magnetic fields in the vicinity of the coded electromagnetic valve bottle stoppers and trigger an alarm indicating possible fraudulent dispensation of liquor.
