Fire Alarm Cause And Effect Matrix -

: The programmed system is tested point by point against the matrix during Factory Acceptance Testing (FAT) and Site Acceptance Testing (SAT) to confirm it behaves exactly as specified.

The document is typically formatted as a spreadsheet or table. fire alarm cause and effect matrix

The final input/output (I/O) matrix must reflect the actual programming at project completion. This "as-built" documentation is a key requirement of standards like NFPA 72 and BS 5839-1. : The programmed system is tested point by

This is the simplest approach, where any activation triggers an immediate general alarm across the entire building. It is common in smaller, less complex buildings. This "as-built" documentation is a key requirement of

In the United States, NFPA 72 outlines explicit expectations regarding how notification appliances behave, the spacing of detectors, and the integrity of circuit survivability. The documentation of input/output logic is a requirement during the system plan review phase.

: The finalized cause and effect matrix becomes the primary input for programming the fire alarm control panel. The logic is translated into code or configuration data that the system will follow.
