1. A system comprising:
- a plurality of ambient condition detectors, where at least some of the detectors are energized by a respective internal replaceable battery and include a respective RFID-type tag added to each of the at least some detectors, wherein the detector includes a tag interface coupled to the tag;
the respective RFID-type tag responds to external interrogation even when a corresponding detector of the at least some detectors is switched off or inactive, where at least current status information relative to the corresponding detector including one or more of detector model number, detector serial number, gas type of detector, operator name, latest calibration date, last bump test date, last alarm date, power up self-test status and current status information is encoded in the tag by a processor of the corresponding detector prior to any interrogation of the respective RFID-type tag and wherein upon interrogation, the respective RFID-type tag reads whether the corresponding detector is in an active state or an off state and reports the status information.

Abstract
In large systems of ambient condition detectors the respective detectors can each include an RFID-type tag or integrated circuit. The tag can transmit detector identification information and status information wirelessly to a displaced receiver. Receivers can be installed in docking/test stations as well as in portable units which can be carried by an individual entering, or, moving through a region being monitored by the detectors.

13. A detector comprising:
-
a housing; an article attaching clip attached to the housing; gas detecting circuitry carried by the housing; an internal replaceable battery within the housing that energizes the gas detecting circuitry; and RFID chip circuits added to the housing, the RFID chip circuits are carried by the housing and coupled to the gas detecting circuitry, the RFID chip circuits respond to external interrogation even when the gas detecting circuitry is switched off or inactive, wherein at least current status information of the gas detecting circuitry including at least one or more of detector model number, detector serial number, gas type of detector, operator name, latest calibration date, last bump test date, last alarm date, power up self-test status and current status information is written in the RFID chip circuits by the gas detecting circuitry prior to any interrogation thereof and wherein upon interrogation, the RFID chip circuits reads whether the corresponding detector is in an active state or an off state and reports the status information. - View Dependent Claims (14, 15, 16, 17, 18, 19)
