Cause: Ionization detector + Heat detector in server room → Effect: Open pre-action valve (fill sprinkler pipes) but NO water release until fusible link melts.
To populate the matrix, inputs and outputs are categorized as follows: cause and effect matrix for fire alarm system
Upon any alarm, elevators are recalled to the Ground Floor (or alternate level) to prevent occupants from being delivered to a fire floor. They lock open with doors open for firefighter use. Cause: Ionization detector + Heat detector in server
The matrix functions as a structured grid or spreadsheet detailing input triggers and output behaviors. The vertical rows list the system inputs (), while the horizontal columns list the system outputs ( Effects ). The matrix functions as a structured grid or
The purpose of the Cause and Effect Matrix is to provide a clear, graphical representation of the fire system's logic. It translates the fire strategy design into a programmable format for the Fire Alarm Control Panel (FACP). It ensures that the activation of a specific device results in a predetermined, logical response from the building systems.
