FCK Information
Several detectors can be calibrated with one FCK. The only limitation is the amount of gas in the cylinder. The 17 liter cylinder has
approximately 85 minutes of continuous calibration run time. Replacement cylinders are available. The gas cylinder should be replaced
when the pressure gauge on the regulator shows 25-psi or less.
Note: For optimum test results it is suggested that the unit be in clean air, green light on, and be in a low ambient air flow
Gas Testing
Testing the Fan Relay
1. Remove the Philips screw on the front of the CM-6. Remove the front cover.
2. Open the FCK. Connect the 50 ppm gas cylinder to the regulator.
3. Check the pressure gauge on the regulator. If you have 25-psi or less you will need to replace the gas canister.
4. Assemble regulator, hose and Test Hood and place the Test Hood over the CO sensor.
Note: The time to activate the Fan relay depends on the delay setting.
5. Turn on the regulator to start the gas flow and wait with the gas applied continuously.
6. With the display function turned “On”, the CM-6 will show the current concentration of CO or “0” (zero) in clean air. When the
CO concentration reaches the Fan Relay setting (35 ppm, for example) the display will flash back and forth between “FAn” and
“35”. With the display function turned ”Off”, the display does not show the CO concentration, but will show “FAn” as long as the
fan relay is activated.
Note: If the Fan relay does not close within 2 minutes, there are four possibilities:
a. Gas cylinder is empty, check the pressure gauge. Replace the gas cylinder if 25psi or less.
b. Unit needs to be re-calibrated (go through recalibration and re-test).
c. Detector is in need of servicing (return unit to factory for servicing).
d. Detector has fan relay set to disable (OFF) or 100ppm. Set fan relay to 25ppm and repeat the test.
7. Remove the gas from the sensor. Proceed to Test the Alarm relay or replace the top cover.
