NOTE:
Performing a response test on the H
2
S detectors may cause
alarms. Be sure to disable external alarms or put the Beacon 200
into its calibration program before performing this test.
Preparing for the response test
1. While in normal operation, press and hold the UP/YES button for 5
seconds and press the UP/YES button again when asked if you would
like to enter Calibration Mode.
2. Verify that the Beacon 200 display reading is 0 ppm H
2
S.
3. If the display reading is not 0 ppm H
2
S, set the zero reading of the
detector as described in the Start Up section of this manual, then
continue this procedure.
4. Screw the regulator into the H
2
S calibration cylinder.
5. Use the calibration kit sample tubing to connect the regulator to the
calibration cup/splash guard of the first detector.
Performing the response test
1. Turn the regulator’s on/off knob counterclockwise to open the regulator.
Gas will begin to flow.
2. Allow the gas to flow for one minute, then verify that the reading is
within ± 20% of the cylinder gas concentration.
NOTE:
If the reading is not within ± 20% of the correct response reading,
calibrate the detector as described in the Calibration section of
this manual.
3. Turn the regulator’s on/off knob clockwise to close the regulator.
4. Detach the sample tubing from the first detector and attach it to the
calibration cup/splash guard of the second detector.
5. Turn the regulator’s on/off knob counterclockwise to open the regulator.
Gas will begin to flow.
6. Allow the gas to flow for one minute, then verify that the reading is
within 20% of the cylinder gas concentration.
NOTE:
If the reading is not within ± 20% of the correct response reading,
calibrate the detector as described in the Calibration section of
this manual.
7. Turn the regulator’s on/off knob clockwise to close the regulator.
