Some buildings with a fire alarm system will also have a fire suppression system. What is required when both systems are installed?

• A. Activation of the suppression system sends an alarm to the building system.
• B. The fire alarm must be silenced when suppression is active.
• C. The suppression system operates independently without signaling the building system.
• D. The building system must be on a separate power supply.

Answer: (A)

When a building has both a fire alarm and a fire suppression system, the actuation of the suppression system must be integrated with the fire alarm so that the suppression release sends an alarm signal to the fire alarm control panel. This creates a coordinated response: occupants hear the alarm and evacuation proceeds, while building systems (like elevator recall and HVAC shutdown) and responders are notified and can react appropriately. Silencing the alarm during suppression would hide a critical activating event and impede evacuation and response. The suppression system should not be completely independent from the building system, since coordinated signaling is essential for safety. A separate power supply for the building system isn’t the requirement here; the key point is that suppression activation triggers the building’s alarm system.
