Rapidrop RD020 fire sprinklers are conventional upright pendant (CUP), standard response, frangible glass bulb automatic sprinklers with CE, VdS and LPCB approvals.

They are standard orifice fire sprinklers for installation in fire sprinkler systems designed in accordance with standard installation rules, e.g. EN12845 or the requirements of the authority having jurisdiction.

CUP sprinklers produce a spherical water discharge pattern. In the instance of fire, the heat causes the fluid in the glass bulb to expand which shatters the glass and releases the spring seal assembly. Water flows from the orifice onto the sprinkler deflector which diffuses the water into a uniform spray pattern which extinguishes or controls the fire.
