What is a sidewall sprinkler head?
Sidewall fire sprinklers install along walls or beneath beams where ceiling piping is unavailable, or where aesthetic concerns or obstructions weigh against the use of other sprinkler types. Most are designed to protect small rooms, closets, or hallways and have a semicircular deflector that produces a crescent-shaped spray pattern.
What’s the difference between rated working pressure and testing pressure?
Rated working pressure means pressure under normal conditions.
Testing pressure means pressure for strength test of products.
How to choose the fire sprinkler heads?
The selection and application of sprinkler shall be determined according to the fire risk of the protection place, the building structure of the protection space, the characteristics of the automatic sprinkler system, as well as the flow coefficient, thermal sensitivity index RTI and the maximum protection area of the sprinkler.
