Fire Alarm Cause And Effect Matrix - Fix

: Dampers closing and fans stopping to prevent smoke spread.

These are the automated responses, such as sounding horns, flashing strobes, releasing fire doors, shutting down HVAC units, recalling elevators, and notifying emergency services.

The purpose of commissioning is to make sure the system operates correctly, including verifying that all sensors function correctly, all outputs operate correctly, and the cause and effect linkages are correct. This involves end-to-end testing, not just at the panel level, to ensure the correct sequence of outputs and the operation of all interfaced systems.

A fire alarm cause and effect matrix is a document that outlines the specific actions that occur when a fire alarm system detects a fire or an alarm signal. The matrix typically consists of two axes: the causes (or events) and the effects (or actions). The causes may include events such as: fire alarm cause and effect matrix
