Bump Test

Gas Cylinder Guidelines (Bump Test)

• To ensure an accurate bump check, use a premium-grade gas. Use gases approved by the National Institue of Standards and Technology.
• Do not use a gas cylinder that is past its expiration date.

Gas Cylinder Connection

1. Connect the calibration hose of the 0.5 l/min regulator on the gas cylinder. For use with the MicroDoock II, use a demand flow regulator.

NOTE: Cylinders that are used with a demand flow regulator must meet the following maximum inlet pressure specification:

• Disposable cylinders 0-1000 psig/70 bar
• Refillable cylinders 0-3000 psig/207 bar

To perform an automated bump check, refer to the MicroDoock II User Manual.

2. Connect the calibration hose to the calibration cap.

3. Attach the calibration cap to the detector.

4. Apply gas. Verify the visual and audible alarms activate.

5. Close the regulator and remove the calibration cap from the detector.
NOTE: The detector will temporarily remain in alarms until the gas clears from the Sensors.

6. Disconnect the hose from the calibration cap and the regulator.
