65-2496RK CO Detector ........ -
Page 5: Overview
The 65-2499RK CO detector includes the 65-2496K CO detector and a junction box. This manual may also be used for the 65-2496RK CO detector which does not include a junction box and is normally mounted in one of a controller’s conduit hubs. If you are using a 65-2496RK CO detector, disregard all references to the junction box and junction box terminal strip. -
Page 6: Description
This section describes the components of the 65-2496RK and 65-2499RK detectors. The 65- 2499RK includes the 65-2496RK CO detector and a junction box. A two point terminal strip is provided inside the junction box for detector connections. The 65-2496RK does not include a junction box. -
Page 7: Junction Box
A terminal block within the junction box facilitates the wiring connections. A cover on the front of the junction box allows access to the interior of the junction box. 65-2496RK/65-2499RK CO Detector • 3 GlobalTestSupply www. -

Page 9: Wiring The Co Detector To A Controller
Connect the wires to the applicable controller terminal strip. See the controller operator’s manual and the controller’s detector head specification sheet for the 65- 2499RK detector. 65-2496RK/65-2499RK CO Detector • 5 GlobalTestSupply www. .com Find Quality Products Online at: sales@GlobalTestSupply.com... - Page 10 Figure 4: Wiring the CO Detector to a Controller 10. If using shielded cable, connect the cable’s drain wire to an available chassis ground at the controller. RKI controllers typically have a ground stud that is a convenient grounding location. 6 • 65-2496RK/65-2499RK CO Detector GlobalTestSupply www. .com Find Quality Products Online at: sales@GlobalTestSupply.com...

Page 11: Startup
If the display reading is 0 ppm, start up is complete. The CO detector is in normal operation. If the display reading is not 0 ppm, continue with step 3. Perform a zero (fresh air) adjustment operation at the controller.

NOTE: If the reading is not within ± 20% of the correct response reading, calibrate the detector as described in “Calibration” on page 13. Turn the regulator’s on/off knob clockwise to close the regulator. Unscrew the regulator from the calibration cylinder. 8 • 65-2496RK/65-2499RK CO Detector GlobalTestSupply www. .com Find Quality Products Online at: sales@GlobalTestSupply.com... -

- Page 16 See Figure 4 on page 6 for wiring to a generic controller. See the controller operator’s manual and the controller’s detector head specification sheet for the 65-2496RK detector for wiring specific to your controller. If the detector is installed remotely from a controller in a junction box, connect the detector leads to the terminal block the same way the old detector was wired (see Figure 4 on page 6).

Page 17: Calibration Frequency
Although there is no particular calibration frequency that is correct for all applications, a calibration frequency of every 3 months is adequate for most CO detector applications. Unless experience in a particular application dictates otherwise, RKI Instruments, Inc. recommends a calibration frequency of every 3 months for the CO detector. -
Page 18: Setting The Zero (Fresh Air) Reading
NOTE: If you do not allow the gas reading to decrease below the alarm points, then unwanted alarms may occur. Verify that the controller display reading decreases and stabilizes at 0 ppm. Store the components of the calibration kit in a safe and convenient place. 14 • 65-2496RK/65-2499RK CO Detector GlobalTestSupply www. .com Find Quality Products Online at: sales@GlobalTestSupply.com... -
