What do discharge indicators in fire extinguishing systems primarily show?

Discharge indicators in fire extinguishing systems serve to provide immediate visual evidence of container overpressure. This is crucial for safety and operational efficiency, as they allow personnel to quickly assess whether the system is functioning correctly and whether the extinguishing agent is ready for deployment. When an extinguishing agent is discharged, the indicators will visibly reflect this change, confirming that the system has been activated.

In fire suppression systems, maintaining the correct pressure in the container is essential for effective operation. The presence of a discharge indicator confirms that the necessary conditions are met for the agent to be effective, ensuring that a fire can be suppressed promptly should the need arise.

This functionality is particularly critical during emergency situations, where every second counts, and clear visual indicators provide reassurance that the system is operational and ready to engage.
