Claim:
A device to report an alarm condition, comprising: a housing; a detector within the housing, the detector being configured and arranged to detect a concentration that exceeds a threshold value and to generate an alarm condition signal indicative of an alarm condition in which the detected concentration exceeds the threshold value; and a global system for mobile communications (GSM) module within the housing, the GSM module being configured and arranged to report the alarm condition via a short message service (SMS) as a message containing a selection from a group consisting of a contact identification (ID) format and an SMS header, the detector and the GSM module being configured and arranged so that the detector transmits the generated alarm condition signal to the GSM module; means for detecting a diminished power level that is less than a full power level for powering the GSM module; power level detector means for generating a further signal indicative of the detected diminished power level, the GSM module being configured to receive the generated further signal for transmitting a corresponding signal via the SMS; and setting means within the housing that is responsive to receipt of remotely sent instructions via the SMS to change a setting of at least one of the contact ID format and the SMS header by replacing the at least one of the contact ID format and the SMS header with a substitute.
