Overview This manual describes the 65-2433RK-05 carbon monoxide (CO) detector. This manual also describes how to install, start up, maintain, and calibrate the detector when it is used with a gas monitoring controller. A parts list at the end of this manual lists replacement parts and accessories for the CO detector. Specifications WARNING: Do not use this product in a manner not specified in this instruction manual. Table 1 lists specifications for the CO Detector.
Description This section describes the components of the CO detector. The detector consists of the CO sensor, charcoal filter with rubber boot, detector housing body, detector housing cap, and cap gasket. Detector Housing Body Cap Gasket Plug-In CO Sensor Rubber Boot With Charcoal Filter Detector Housing Cap Flame Arrestor Guard Figure 1: CO Detector Component Location Detector Housing, Housing Cap, & Cap Gasket The detector housing body protects the sensing components within the housing.
Installation This section describes procedures to mount the CO detector in the monitoring environment and wire the detector to a controller. Mounting the CO Detector 1. Select a mounting site that is representative of the monitoring environment. Consider the following when you select the mounting site. • Select a site where the detector is not likely to be bumped or disturbed. Make sure there is sufficient room to perform start-up, maintenance, and calibration procedures.
NOTE: If the mounting site requires the detector installation to be explosion proof, you must install the detector in a Killark HKB junction box with a Killark HFC, HK2D, or HK4D cover. Wiring the CO Detector to a Controller WARNING: Always verify that the power source is OFF before you make wiring connections. 1. Turn off the controller. 2. Turn off or unplug power to the controller. 3. Remove the junction box cover.

Connect the cable’s drain wire to an available chassis ground at the controller. 10. Reinstall the junction box cover.
Start Up This section describes procedures to start up the CO detector and place the detector into normal operation. Introducing Incoming Power 1. Complete the installation procedures described earlier in this manual. 2. Verify that the power wiring to the controller is correct and secure. Refer to the controller operator’s manual. 3. Turn on power to the controller. 4. Turn on the controller. 5. Verify that the controller is on and operating properly. Refer to the controller operator’s manual.
Maintenance This section describes maintenance procedures. It includes preventive maintenance, troubleshooting, and component replacement procedures. Preventive Maintenance This section describes a preventive maintenance schedule to ensure the optimum performance of the CO detector. It includes daily, monthly, and quarterly procedures. Daily Verify a display reading of 0 PPM CO at the controller. Investigate significant changes in the display reading.
6. When the controller display reading falls below the alarm setpoints, return the controller to normal operation. 7. Store the components of the calibration kit in a safe place. Quarterly Calibrate the CO 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 CO detector. NOTE: This troubleshooting guide describes detector problems only.
Replacing Components of the CO Detector This section includes a procedure to replace the CO sensor, the charcoal filter, and the entire detector assembly. In most cases, it is not necessary to replace the entire detector assembly. Replacing the Plug-In CO Sensor CAUTION: The sensor contains electrolyte which is a dilute acid. Do not disassemble the sensor when replacing it with a new one. If sensor electrolyte comes in contact with your skin, wash affected area thoroughly with soap and water. 1.
11. Turn on or plug in power to the controller. 12. Turn on the controller and place into normal operation. Replacing the CO Detector NOTE: In most cases, it is only necessary to replace the CO sensor. 1. Turn off the controller. 2. Turn off or unplug power to the controller. 3. Remove the junction box cover. 4. Disconnect the detector leads from the terminal block in the junction box. Note the position of the color-coded leads as you remove them. 5. Unscrew the detector from the junction box hub.
Preparing for Calibration NOTE: Calibrating the CO detector may cause alarms. Be sure to put the controller into its calibration program or disable external alarms before calibrating. WARNING: Do not remove the detector housing cap while the circuits are energized unless the area is determined to be non-hazardous. Keep the detector housing cap tightly closed during operation. 1. Screw the calibration cup onto the bottom of the CO detector. 2. Screw the regulator into the calibration cylinder. 3.
NOTE: If you do not allow the gas reading to decrease below the alarm points, then unwanted alarms may occur. 8. Verify that the controller display reading decreases and stabilizes at 0 ppm CO. 9. Store the components of the calibration kit in a safe and convenient place. Parts List Table 5 lists replacement parts and accessories for the CO detector.
