Optional Cascade Kit
NOTICE:
Use the Intelligent Cascading Kit only if low activation flows are
desired, and if it doesn't matter if full flow is not available
instantly. If the application demands higher flow rates more
quickly, do not install the Intelligent Cascading Kit.
If the Intelligent Cascading Kit is used the minimum activation
flow rate is equal to the activation flow rate of a single unit.
