HS300 is Standard/Quick Response frangible glass bulb automatic sprinklers. They are CE Marked and built according to LPCB, UL and UL listed bulbs, standard orifice fire sprinklers for installation in fire sprinkler systems. 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 in order to control the fire.
Sidewall Sprinklers are designed for installations along a wall or side of a beam beneath a smooth ceiling.
