The auto-sensitivity feature for Model OH121 stems from the internal, self-monitoring circuitry, and provides dynamic verification of sensitivity and/or required maintenance. The auto-sensitivity feature is displayed by Siemens unique (3) three-color LED provided locally on the detector + and optionally with the various remote LED indicators.
