Macurco GD-xx Operation Manual
REV – 2.0.0 [34-2900-0027-6 ] 30 | Page
NOTE: GD-xx must be tested or calibrated at regular intervals in accordance with the requirements of the National
Fire Protection Association (NFPA) 720 or local code requirements. Macurco recommends testing and calibration at
a least once per year at a minimum but depending on the application and risk potential of the application a greater
frequency might be needed. Check with local authorities for any specific local regulations.

Cal-Kit 1 Information
Several detectors can be calibrated with one Cal-Kit. The only limitation is the amount of gas in the cylinder. The 34-
liter cylinder has approximately 170 minutes of continuous calibration run time. 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.
