How long does it take for the fire extinguishing agent in an HRD system to discharge?

In a High Rate of Discharge (HRD) system, the fire extinguishing agent is designed to be released rapidly to combat fires effectively. The typical discharge time of one to two seconds is crucial as it allows the extinguishing agent to rapidly reach the source of the fire, suppressing it before it can spread further. This speed of extinguishing is critical in aviation and other industries where quick responses to fire emergencies can significantly reduce damage and enhance safety.

Discharge times that are longer than this, such as three to four seconds or five to six seconds, may still be effective but are not optimal for immediate fire response. Delays in the discharge time can lead to potentially dangerous situations where the fire could escalate during those extra seconds. Therefore, the one to two second discharge time standard reflects the design intent of HRD systems to provide rapid fire suppression in critical environments.
