In a clean agent system, which component is required to control the timing and release of the agent during discharge?

• A. Agent-releasing devices
• B. Discharge controls
• C. Both agent-releasing devices and discharge controls
• D. Sensor alarms

Answer: (C)

Controlling the timing and release of a clean agent requires both the control logic and the physical release mechanism. The discharge controls provide the sequencing and actuation signals that determine when discharge should occur, while the agent-releasing devices are the components that actually open and release the agent into the protected space. Without the controls, there’s no timed command to discharge; without the releasing devices, the control signal wouldn’t trigger any release. Sensor alarms may detect a condition, but they don’t manage discharge. Therefore, both parts are needed to ensure the agent is released at the right time and in the right amount.
