When replacing old access control locks, you might be forced to fit a square peg into a round hole, as it were, when the old lock leaves an oddly shaped gap in the door. New enhancements to these access control panels include an improved gasket for easier installation and improved weather resistance, plus a slightly taller escutcheon that covers many existing door preparations. It also features a user-generated master code to increase security, plus voice-guided programming in three languages, administrator lock-out functions and ADA compliant levers.
