Simple Access systems are typically complicated, particularly for personnel without an access control background. Proxess is committed to making a system that is simple enough for everyone to take advantage of EAC (electronic access control) functionality. No Door Prep There is no door prep or unsightly holes that need to be drilled to install a Proxess cylindrical lock in an existing, standard (retrofit) door prep, and only a single additional 5/8” hole to install a Proxess mortise lock. Why is this feature important? Installation is simplified, greatly reducing time and cost of projects, especially for multiple and geographically dispersed implementations. It is estimated that the average time to install a typical access control door is four hours. A proxess lock installs in about 10-15 minutes.
