We are designing a clean agent system for electrical rooms located within a high-rise building. We are proposing having dedicated clean agent releasing control panels for the electrical rooms, and a separate building Fire Alarm Control Panel.
Is it mandatory to connect fire/smoke dampers (and other shutdown devices) in the electrical room with the clean agent releasing panel, or can these be connected to the building fire alarm system? Thanks in advance. Sent in anonymously for discussion. Discuss This | Submit Your Question | Subscribe

not sure about the code - but if the dampers play any role in the agent containment, you will want to make sure they close before the agent is discharged.

I agree with both Matt and Doug. Depending on the age of the building FACP the functionality can be reduced from that of a modern panel, however, using solid state (solenoid) relays tied into fire alarm relays, there are a lot of options for setting up your action sequence.

If the clean agent panel is sending alarm, supervisory, and trouble signals to the building’s Fire Alarm Control Panel (FACP), both panels make up one fire detection and alarm system. If the main fire alarm system detects a fire, using staged evacuation, the main FACP will evacuate the building. If the clean agent panel goes into alarm and sets off an alarm in the main building’s FACP, the main FACP will evacuate the building.

I just did an acceptance test on this exact situation. It was done exactly as Doug says. FM-200 system has its own panel that sends signals to the main FACP for the entire building. The main FACP controls all the other functions such as dampers, fire doors, evac, etc.

As the clean agent system is designed to minimize down time and losses, you should minimize the potential points of failure in its execution.

Connecting damper shutdown signal from clean agent panel to HVAC panel is not mandatory. Building fire alarm panel which is connected with fire detector can deliver confirmed fire signal to both HVAC control panel to shutdown damper and clean agent panel to release gas.
