The model Rapidrop RD020 are Conventional, Standard Response frangible glass bulb automatic sprinklers. CE marked, VdS and LPCB approved .
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.
Conventional sprinklers produce a spherical water discharge pattern. In a fire condition 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.
