Cause And Effect — Matrix For Fire Alarm System

| Input (Cause) | Zone Location | Sounders (Evac) | Beacons | Brigade Signal | AHU Shutdown | Elevator Recall | Door Release | | :--- | :--- | :---: | :---: | :---: | :---: | :---: | :---: | | | Zone 1 | X | X | X | X | X | X | | Smoke Det (Level 1) | Zone 1 | X | X | X | X | X | X | | Heat Det (Kitchen) | Zone 5 | X | X | X | X | - | X | | Sprinkler Flow | Plantroom | X | X | X | - | X | - | | Duct Smoke | AHU Room | - | - | X | X | - | - |

| ID | Device Type | Action | Location | | :--- | :--- | :--- | :--- | | O1 | Notification Appliances (Horns/Strobes) | Activate (Temporal 3) | Floor of origin + adjacent floors | | O2 | Magnetic Door Holder | Release (close door) | Fire zone corridor | | O3 | AHU (Air Handler) | Shutdown | Entire building | | O4 | Supply Fan (Stair Pressurization) | Start | Stairwells | | O5 | Elevator Controller | Recall to ground floor & Shunt trip | All elevators | | O6 | Smoke Damper | Close | Duct passing through fire zone | cause and effect matrix for fire alarm system

Below is a simplified excerpt of the logic applied: | Input (Cause) | Zone Location | Sounders
