Lists the Output Functions (The Effects).
The "Cause" column lists every device or condition that can send a signal to the fire alarm panel. Common triggers include:
Sending elevators to a primary or alternate floor so people don’t get trapped.
It maps out every possible "trigger" (an initiating device) and pairs it with a specific "action" (an output function). Without this matrix, a fire alarm system is just a collection of parts; with it, the system becomes a coordinated life-safety strategy. The "Cause" Side: Initiating Devices
Non-fire events that need attention, like a closed valve or a low-pressure switch in a tank. The "Effect" Side: Output Responses
