Abstract
A switch status monitoring system (10) includes a switch signal processor (16) that operates in either of a supervised mode or an unsupervised mode for each monitored switch (12). Selection of the operating mode is made via configuration data provided to the switch signal processor, for example, from an applications processor (20). In this manner, reconfiguration of the mode of monitoring, supervised or unsupervised, of any particular switch within a system is accomplished by providing revised configuration data and without changes or modifications to the switch signal processor hardware. As will be appreciated, the present invention has application in for example door or window monitoring systems and in other similar security system applications.
