gtS - Gas Test, 3 minutes (no output to the panel during the gas test)
The display will flash during the test, or in the case of the gas test, the gas level will alternate with gtS. Once the test is complete, the
display will return to a steady display. To exit the test menu, press the Next button until "End" is displayed then, press Enter to return to
normal mode.

Carbon Dioxide Gas Test

The following steps must be performed when conducting a calibration verification test (bump test) to ensure proper performance of the
monitor. Failure to do so may adversely affect product performance and result in serious injury or death.

When performing a calibration verification test (bump test) only use certified calibration gas at the required concentration level.

Do not test with expired calibration gas.

If the instrument cannot be calibrated, do not use until the reason can be determined and corrected.

Do not cover or obstruct display or visual alarm cover.

Ensure sensor inlets are unobstructed and are free of debris.

FCK Information

Several detectors can be calibrated with one FCK. The only limitation is the amount of gas in the cylinder. The 34-liter cylinder has
approximately 175 minutes of a continuous test run time. Replacement cylinders are available. The gas cylinder should be replaced when
the pressure gauge on the regulator shows 25-psi or less or has reached its expiration date.
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.

4.4 Gas Testing

4.4.1

Testing the Fan Relay

1. Remove the Philips screw on the front of the CD-6"x". Remove the front cover.
2. Open the FCK. Connect the 5000-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. Check the
expiration date on the cylinder, if it has passed the expiration date the cylinder should be replaced.
4. Assemble regulator, hose, and Test Hood and place the Test Hood over the CO
Note: The time to activate the Fan relay depends on the delay setting. See section
