Testing an approved interface matrix
A coordinated test exercise involves a fire alarm input and several outputs listed in an approved cause-and-effect matrix. The matrix identifies the intended notification, door-control response and a separate status-feedback point. One technician sees a command in the panel log and marks every connected function as passed without observing the other systems. Another proposes changing the programmed response during the witness test without design review because a door behaves differently from expectation. Responsible representatives for the connected trades are available. The scenario provides no universal rule that every door must unlock on every alarm or power loss. Students must explain how the approved sequence, actual response, feedback, restoration and recorded discrepancies should guide a meaningful integrated test.
1. What evidence demonstrates the required response?
Read the worked answer
Compare the specific approved input/output conditions with observed operation and the intended feedback, involving the responsible connected trades. A command record alone does not establish every physical response.
2. How should a discrepancy be handled?
Read the worked answer
Record and investigate it against the approved design and equipment information. Coordinate any authorized change, update records and retest the affected functions rather than making an undocumented witness-test alteration.
