Where must audible and visual pre-discharge alarms be provided?

• A. At the building exterior
• B. In the control room
• C. Outside the protected area
• D. Within the protected area

Answer: (D)

The warning devices are meant to alert people who are actually inside the space that will be filled with the clean agent. Providing audible and visual pre-discharge alarms within the protected area ensures occupants hear and see the alert where they need to respond, giving them time to evacuate before discharge occurs. If the alarms were placed outside the protected space or only in a control room, those inside the area might not hear or notice the warning due to doors, walls, or noise, which could delay evacuation. For that reason, the required placement is inside the protected area.
