Analog Inputs give each sensor's reading, 5/15/60-minute time-weighted averages, alarm state, status bits and calibration/life days, plus relay and device status. Analog Values hold gas type and span, warning/alarm setpoints and hysteresis, fire-safety TWA and IDLH setpoints, relay timing and the RS-485 settings.",
