Which statement is true regarding the signals between suppression controls and main fire alarm controls?

• A. Each suppression control must transmit its own independent supervisory signal.
• B. Suppression controls transmit a single, common supervisory signal to the main fire alarm controls.
• C. Suppression controls do not connect to the main fire alarm controls.
• D. The system requires only a notification signal.

Answer: (B)

In a coordinated fire protection system, suppression controls communicate their status to the main fire alarm control panel using a single, common supervisory signal. This setup gives the main panel a unified view of the suppression system’s state—normal, inhibited, faulted, or in operation—so the panel can monitor and respond appropriately. A single supervisory signal avoids confusion that would come from multiple independent signals and ensures consistent, centralized status reporting. If each suppression control sent its own independent signal, the panel could receive conflicting information and the status could become unclear. If suppression controls didn’t connect to the main panel, there’d be no centralized awareness of suppression activity or faults. Relying only on a notification signal would omit the critical supervisory information about the suppression system’s status, which is essential for safe and effective fire protection coordination.
