1. An interface comprising:
- a port that communicates with one of N detectors, where N is an integer greater than 1;
a classification module that communicates with said port and classifies said one of N detectors as one of an analog detector and a digital detector, and that selectively generates detector type information based on said classification, wherein said classification module comprises a voltage divider that comprises a resistance and that adjusts a voltage of the interface based on said resistance in parallel with a resistance within said one of said N detectors, wherein said classification module classifies said one of N detectors based on said voltage; and
a detector identification (ID) module that determines a detector type of said one of N detectors based on said detector type information.

Abstract
An interface includes a port that communicates with one of N detectors, where N is an integer greater than 1. A classification module communicates with the port and classifies the detector as one of an analog detector and a digital detector. The classification module selectively generates detector type information based on the classification.

12. An interface comprising:
-
a port that communicates with N external detectors, where N is an integer greater than 1; a voltage divider that comprises a resistance and that adjusts a voltage of the interface based on said resistance in parallel with a resistance within one of said N external detectors; an ammeter that measures a current supplied by the interface to said one of N external detectors based on said one of N external detectors classified as an analog detector; a digital communications peripheral module that requests detector type information from said one of N external detectors based on said one of N external detectors classified as a digital detector; and a detector identification (ID) module that generates a detector type signal of said one of N external detectors based on said classification, wherein said detector ID module determines said detector type of said one of N external detectors based on said measurement of said current, wherein said detector ID module determines said detector type of said one of N external detectors based on digital communications peripheral module signals. - View Dependent Claims (13, 14, 15)
