33023 is a Level II General Non-Core Work element.

The asterisk (*) following 33023 means crossover credit exists in selected other fields/subfields for this work element. Read information on crossover work elements in the Program Detail Manual on pages 4 and 5. You won't receive the crossover credit until you test in another qualified sub-field for the first time.

Understand the basic principles of operation of ionization, aspiration, projected beam, photoelectric obscuration, photoelectric scattering, and cloud chamber smoke sensing fire detectors, and the effect of stratification on response time. Lay out a system of smoke sensing fire detectors of line type, spot type, duct type, and sampling type, including smoke detectors for use as area smoke detectors, air duct smoke detectors, and smoke detectors for door release service.
