Product Warranty RKI Instruments, Inc. warrants gas alarm equipment sold by us to be free from defects in materials, workmanship, and performance for a period of one year from date of shipment from RKI Instruments, Inc. Any parts found defective within that period will be repaired or replaced, at our option, free of charge.
± 0.5% O WARNING: When using the 65-2320RK, you must follow the instructions and warnings in this manual to assure proper and safe operation of the 65-2320RK and to minimize the risk of personal injury. Be sure to maintain and periodically calibrate the 65-2320RK as described in this manual.
NPT mounting threads at the top of the detector allow you to mount the detector to the junction box or a 3/4’’ NPT conduit fitting. Two color-coded leads extend from the top of the detector. The leads allow you to connect the detector to a controller. 2 • 65-2320RK Oxygen Transmitter 1.800.561.8187 information@itm.com www.
Use the cover on the front of the junction box to access the interior of the junction box. The detector and amplifier are factory installed in the junction box. Three spacers installed on the back of the junction box control the distance of the junction box 65-2320RK Oxygen Transmitter • 3 1.800.561.8187 information@itm.com www.
Oxygen for Calibration Cup Detector Figure 2: Mounting the Oxygen Transmitter At the monitoring site you select, hang or mount the junction box with the detector facing down (see Figure 2). 4 • 65-2320RK Oxygen Transmitter 1.800.561.8187 information@itm.com www. .com...
The power cable may disrupt the transmission of the transmitter signal to the controller. 11. Connect the wires to the applicable detector/transmitter terminal strip at the controller as shown in Figure 3. 65-2320RK Oxygen Transmitter • 5 1.800.561.8187 information@itm.com www.

12. If shielded cable is used, connect the cable’s drain wire to an available chassis (earth) ground at the controller. RKI controllers typically have a ground stud that can be used to ground the cable’s drain wire. 6 • 65-2320RK Oxygen Transmitter 1.800.561.8187 information@itm.com www.
The procedure below describes applying zero emission air, usually called zero air, using a calibration kit that includes a calibration cup, calibration gas, sample tubing, and a fixed flow regulator with an on/off knob. RKI Instruments, Inc. recommends using a 0.5 LPM (liters per minute) fixed flow regulator.
NOTE: If the reading does not decrease, calibrate the detector as described in “Calibration” on page 11. Remove the voltmeter leads from the amplifier test points, then secure the junction box cover to the junction box. 8 • 65-2320RK Oxygen Transmitter 1.800.561.8187 information@itm.com www.

Step 5 above. A foam gasket that orients the amplifier and keeps it from rotating is installed on the bottom of the amplifier. Make sure the amplifier is seated flat in the junction box. 10 • 65-2320RK Oxygen Transmitter 1.800.561.8187 information@itm.com www.
Set a voltmeter to measure in the millivolt (mV) range. Plug the voltmeter leads into the test points on the amplifier. Plug the positive lead into the red + test point; plug the negative lead into the black - test point. 65-2320RK Oxygen Transmitter • 11 1.800.561.8187 information@itm.com www.
Turn the regulator knob clockwise to close the regulator. Unscrew the regulator from the calibration cylinder. Unscrew the calibration cup from the detector housing. NOTE: For convenience, leave the regulator and calibration cup connected by the sample tubing. 12 • 65-2320RK Oxygen Transmitter 1.800.561.8187 information@itm.com www. .com...
