Arrow Lock has tested its Revolution Touch-screen keyless entry system under the world's harshest conditions, including fire, water, impact, and freezing cold. The result: Revolution proved rugged even in the toughest challenges. The affordable, aesthetic Revolution is ideal for hospitals, schools, churches, and university buildings that need to limit traffic to controlled areas, and reduces the need to distribute and keep track of multiple keys. Installation is simple and takes approximately five minutes for a properly prepped door. A multi-lingual voice prompt guides the user through the programming process to select set-up codes and authorize users, eliminating the need to break out bulky instruction manuals for each programming change. Up to 1,000 codes are available in advanced mode. Best of all, the lock performs reliably in both interior and exterior environments.
