1. A data collection device, comprising:

  • at least one processor;

    a communications system communicably coupled with the at least one processor, the communications system capable of communicating with one or more gas sensing devices, over a network; and

    a memory communicably coupled with the at least one processor, the memory configured to store detected concentrations of a particular gas reported by gas sensors associated with the one or more gas sensing devices,wherein the at least one processor is configured to;

    receive reports of detected concentrations of the gas from the one or more gas sensing devices in accordance with one or more predetermined schedules respectively associated with the one or more gas sensing devices;

    receive an alarm from an alarming gas sensing device of the one or more gas sensing devices indicating that a detected concentration of the gas is greater than a predetermined threshold;

    receive updated reports of detected concentrations of the gas automatically provided from the alarming gas sensing device at a rate faster than that provided by the predetermined schedule respectively associated with the alarming gas sensing device;

    track a rate that the detected concentration of the gas at the alarming gas sensing device is increasing or decreasing; and

    send a clear alarm command to the alarming gas sensing device when the tracked rate at the alarming gas sensing device indicates a decrease in concentration of the gas at a rate at which there is no safety concern.
