HS100 Pendent Standard Response Sprinkler
HS100fire sprinklers are pendent, standard response, frangible glass bulb automatic sprinklers.
They are made according to CE Marked, LPCB, VdS, FM approved, UL listed bulbs, standard orifice fire sprinklers for installation in fire sprinkler systems.
HS100 Sprinklers produce a hemispherical water distribution pattern below the deflector. 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.
