    How to test the D382 or Macurco GD-2A Combustible Gas Detector

    Once the unit is fully operational (the green light is on steady), test the unit by directing gas from an unlighted butane cigarette lighter into the detector near the left hand side through one of the vent holes. It will be necessary to hold the lighter valve open for several seconds. The red light (ALARM) will turn on, the alarm relay switches, and any devices connected should activate.

    The detector should be tested regularly by using gas from an unlit cigarette lighter, as detailed above.

    NOTE:
    1.   The notification circuit must sound a Temporal Code 4 pattern when gas is detected and not any other burg or fire pattern. 

    2.  When explosive gas may be present, do not activate a notification circuit in the area where the detector is located.
