The Schlage Electronics CO-100 series standalone electronic cylindrical lockset with satin chrome finish and Rhodes-style lever handle is battery powered, provides a secure door latching system for storeroom and classroom use, includes a manually programmed keypad to verify access credentials of up to 500 users, and accepts a Best SFIC core. The lockset assembly functions independently and without a control system; access credentials and lock status are modified using the keypad and are stored on the lock. The 12-button keypad requires a three-to six-digit code to unlock the door and provides increased security compared to cards and manual keys, which can be lost. The cylindrical lock installs more easily than a mortise lock.The angular Rhodes-style lever handle is made of pressure-cast zinc and can be installed as right or left handed. The lever is designed to accept a Best small format interchangeable core (SFIC) to enable mechanical override of the electronic system. Three colored LED lights and an audio signal can be programmed to indicate when credentials are validated or denied. LED lights can also be programmed to indicate when batteries are running low. The inside handle does not lock, allowing users to exit any time.SpecificationsSpecifications metLockset meets ANSI/BHMA A156.25, ANSI/BHMA Grade 1, UL 294, UL 10 C, FCC Part 15, ADA and RoHS specifications.Exterior housing dimensions9.46 x 3.44 x 3.67 inches (H x W x D)*Interior assembly dimensions10.10 x 3.44 x 2.96 inches (H x W x D)*Compatible door thickness1-3/4"Backset2-3/4"Power supply4 AA batteries*H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right not including the lever; D is depth, the horizontal distance from front to back including the lever.For more information, see the manufacturer's literature.Electronic door locking systems use electric current to control and secure access. Entry is regulated with a door access device such as a keypad or a reader that limits entry to authorized users. Some systems can designate user access for specific hours or days and may include a keyway for mechanical override. Common electronic locking mechanisms include electromagnetic locks and electric strikes. These systems are hardwired or battery powered, which is suitable when electrical wiring is not readily available. Locks are available in cylindrical and mortise styles. A cylindrical lock requires two bored perpendicular holes in the door for installation: one in the door face and a crossbore hole in the door edge. A mortise lock fits into a pocket recess in the door edge.Schlage Electronics, an Allegion brand, manufactures security products for commercial and residential use.
