Lesson 1Assembly verification: interpreting labels, cross-referencing manufacturer’s listing, and documenting missing or altered labelsGuides learners through verifying complete assemblies by interpreting labels, cross-checking manufacturer listings, and documenting missing or altered labels that may invalidate fire door ratings in New Zealand inspections.
Reading and decoding label dataUsing manufacturer listings and guidesConfirming component compatibilityRecognising field-altered assembliesDocumenting nonlisted substitutionsLesson 2Hardware inspection: closers, latches, strike plates, pivots, self-closing devices, coordinated hardwareAddresses systematic hardware inspection, including closers, latches, strikes, pivots, and coordinated devices, ensuring components function together for reliable self-closing and latching in New Zealand fire doors.
