International Electronics Inc. (IEI) releases the Door*Gard LS-1 intelligent lockset. The LS-1 combines IEI keypad technology with a rugged grade one lockset resulting in an indoor/outdoor system that is both durable and attractive. Plus, the LS-1 is designed for the fastest installation possible. In most cases only a single additional hole is required to install the LS-1 onto a protected door. Unique functions include a propped door and forced door alert when used with a standard magnetic contact. Standard features include metal alphanumeric Braille keys, 120 users, two stage low battery alert (powered from four standard AA batteries), one to six digit code length, service codes for one-time entry and passage/toggle codes allowing the door to remain open.
