Detailed description of HD Fire CNS and CN Diaphragm Sprinklers
The HD sprinkler does not open automatically, for external use to protect windows, walls, steel beams, columns, roofs and any other structure against fire and heat exposure. The sprinkler head is usually installed with the hole slot facing downwards. Curtain sprays absorb and reflect heat radiation, minimizing the amount of heat reaching the structure/area to be protected.
