The Blurb:

The PAC (Presco™ Access Controller) Door access controllers utilise proven microprocessor technology to operate an electric door locking device.Together with a Presco™ encoder, or other devices with the addition of a Presco™ Interface Module model PIM. The PAC offers affordable access control to restricted areas for up to 400 users.

With the Presco system the door controller and reader are separated, allowing the controller to do the code processing in a remote protected environment. The code is transmitted from the reader using only two wires, making installation simple and cost effective. The door controller and reader can be separated by up to 1 kilometer using low cost 4 core non-shielded cable!
