1. A method comprising:
- establishing a device address;
requesting a pre-assigned identification number of the device; and
responsive to the requesting, evaluating received results and if the results are not indicative of a missing device, issuing a command using the results as a device identification number to provide an associated address; and
comparing the device address to the associated address, and if they are the same, issuing a disable command to the device having that device identification number.

Abstract
A plurality of detectors can be evaluated to determine if more than one has been assigned the same address. Responsive thereto, such detectors could be identified for follow-up maintenance, or service.

10. An apparatus that evaluates addresses assigned to a plurality of devices comprising:
-
a programmable processor; software which establishes an address to be evaluated; software, executable by the processor, that issues a request for a device identification number to at least one device having the address assigned thereto; and
if the response is not a no device present indicium, the processor issues a command, using the response as a device identification number, to provide an associated address;software executable by the processor that evaluates the associated address for the presence of multiple responses and including comparing the device address to the associated address, and if they are the same, issuing a disable command to the device having that device identification number. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. An apparatus that evaluates addresses assigned to a plurality of devices comprising:
-
a programmable processor; software executable by the processor which establishes an address to be evaluated; software, executable by the processor, that issues a request for a device identification number to at least one device having the address assigned thereto; software executable by the processor that evaluates a received identification number for the presence of multiple responses; where a medium couples the processor to members of the plurality of devices; where the processor issues commands, via the medium, to members of the plurality; where the processor issues a command to a device, having a selected address, to provide its serial number; and where the processor evaluates a response from the device, and, if the response is not a no device present indicium, the processor issues a command, using the response as a serial number, to provide the associated address and including comparing the device address to the associated address, and if they are the same, issuing a disable command to the device having that device identification number. - View Dependent Claims (18, 19)
