摘要： There is disclosed herein an improved card reader for a security system utilizing a central controller and a plurality of card readers for controlling traffic through critical doors in a facility. The improved reader includes means for improving the system throughput by buffer storing large numbers of transactions all occurring within a short time for time clock functions in time and attendance applications for hourly employees. Also disclosed are means for conditioned emergency responses to sensed changes in status of alarm contacts coupled to the reader and located in the vicinity of the reader within 2 miles. There is also disclosed means for temporarily storing transaction information for transactions made during periods when communications with the controller are lost. During such degraded mode operation, access is granted to cardholders with the proper system code and their ID code and the time of the transaction are stored in a buffer. When communications are restored, the transactions saved in the buffer are sent to the controller.
摘要翻译： 本文公开了一种用于安全系统的改进的读卡器，其使用中央控制器和多个读卡器来控制通过设施中的关键门的交通。 改进的阅读器包括用于通过缓冲器存储大量交易来提高系统吞吐量的装置，所述交易全部在短时间内为小时工的时间和出勤应用中的时钟功能发生。 还公开了用于对与读取器连接并且位于读取器附近2英里内的报警触点的状态感测到的变化进行条件应急响应的装置。 还公开了用于暂时存储在与控制器的通信丢失期间进行的交易的交易信息的手段。 在这种退化模式操作期间，持卡人将使用适当的系统代码和他们的ID代码进行访问，并且交易时间被存储在缓冲器中。 通信恢复时，保存在缓冲区中的事务将发送到控制器。
