Which system is most likely to be described as using a blowout indicator disc for monitoring?

The use of a blowout indicator disc is typically associated with fixed fire-extinguishing systems. These systems are designed to automatically detect and suppress fires in specific areas, making them essential for protecting critical components in powerplants. The blowout indicator disc serves as a visual indicator that the system has been activated or discharged, which is crucial for personnel to assess the situation quickly and respond appropriately.

The fixed system is often installed in locations where traditional fire detection methods may not be sufficient, particularly in high-risk areas. Its integration of the blowout indicator disc enhances safety protocols, allowing for immediate acknowledgment of system performance. This indicator is not commonly referenced in the context of portable fire-extinguishing systems, thermocouple systems, or Kidde systems, which serve different functions and do not utilize blowout indicators in the same manner.
