Quick response in-rack sprinklers in addition to ESFR or large drop sprinklers at the ceiling level can greatly reduce the total number of sprinklers required to attain control or suppression. In extreme cases, compartmentalization of the racks and in-rack sprinklers for each compartment can stop the spread of fire to adjacent racks or compartments.

Approved quick response sprinklers shall be utilized for sprinkler installations within downflow airstreams in cleanrooms and clean zones (NFPA 318 2-1.2.2). The use of quick-response sprinklers is intended to overcome some of the tendency for the sprinkler element to be cooled by the downward airflow, thus, causing the sprinkler system to respond to a smaller size fire more quickly than a system utilizing conventional sprinklers. 

Prepare for the unexpected. Someone could easily set off a sprinkler head or damage one. Quick response would be needed to prevent water damage. 

Detector response models These models are used to predict the response time of a detector device to a fire event, so as to predict how quickly an active intervention will be made by a fire reaction system, such as sprinklers or foam sprayers. Such models use calculated fire heat-release to determine the trigger point of a thermal indicator for example, by calculating the time taken for the local air temperature to reach a trigger value. As such they have very specific inputs and outputs and limited objectives specific to certain devices in contrast to more ambitious categories of models, such as egress or fire endurance models.
