This article discusses stand-alone keypad-based devices as single-door security systems.
Abstract
While initial outlay may be expensive, ongoing costs may be less than those for a lock and key. Among lower cost systems, two levels of sophistication are available. The simpler keypad allows one code of three or more digits to be programmed into it. The second level allows individual codes; each employee uses a different code to enter the protected area. Some features of the single code system are a code given to employees who need access to the door at all times, a timer to allow entry only during specified hours, and the ability to adjust the 'door-open' period. With the individual code system, not only is each employee assigned a different code, but also each user can be assigned a specific time for authorized entry. Moreover, an antipassback feature is available, and printers are an increasingly common option. Some systems are expandable. Photographs and charts.
