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 two minutes, 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. Unscrew the regulator from the calibration cylinder.
5. For any additional detectors that you want to test, move the calibration cup to the
detector, screw the regulator into the appropriate gas cylinder and repeat steps 1-4.
6. Unscrew the calibration cup from the detector.
7. When the controller display reading falls below the alarm setpoints, return the
controller to normal operation.
8. Store the components of the calibration kit in a safe place.
Quarterly
Calibrate the multi-point detector as described in the Calibration section of this manual.
Troubleshooting
The troubleshooting guide describes symptoms, probable causes, and recommended
action for problems you may encounter with the multi-point detector.
NOTE: This troubleshooting guide describes multi-point detector problems only. See the
controller operator’s manual for problems you may encounter with the
controller.

Condition Symptom(s) Probable Causes Recommended Action
Fail Condition Controller indicates a
fail condition. • The detector wiring is
disconnected or
misconnected.
• The CO, O
2
, or H
2
S
plug-in sensor is not
properly plugged into
the sockets in the
detector housing body.
• The detector’s zero
reading is low enough
to cause a fail
condition.
• The detector is
malfunctioning.
1. Verify that the detector wiring is
correct and secure.
2. Confirm that the CO, O
2
, or H
2
S plug-
in sensor is installed properly.
3. Perform a zero adjustment. A full
calibration is recommended.
4. If the fail condition continues, replace
the CO, O
2
, or H
2
S plug-in sensor as
described later in this section.
5. If the fail condition continues, contact
RKI for further instruction.
