The PRE (Presco™ Remote Encoder) is designed to be used with the PAC series door access controllers in areas where keypad security is desired, but weather and vandal resistance is not a priority. When a PRE is coupled with any PAC series door access controller you get the benefits of a secure door access control solution with all of the features of the Presco™ system.
With the Presco system the door controller and keypad are separated, allowing the controller to do the code processing in remote protected environment. The code is transmitted from the keypad using only two wires, making installation simple and cost effective. The door controller and keypad can be separated by up to 1 kilometre using low cost non-shielded cable!
