Horizontal Sidewall Sprinklers
Description
Horizontal sidewall sprinklers are generally used in lieu of pendent and upright sprinklers because of building construction or installation economy considerations. They are designed for installation along a wall or the side of a beam and just beneath a smooth ceiling. Installed with their centerline of waterway horizontal, these sprinklers produce a quarter‐spherical water discharge pattern that is predominately directed downward and outward from the deflec or; however, a portion of the spray is also directed towards the back wall.
Model BF007/BF008, Standard / Quick Response Horizontal Side- wall Sprinklers (Ref. Figure A), are automatic sprinklers of the frangible bulb type, and standard spray, 1/2” orifice, 5 / 3 mm bulb. They are “standard / quick response ‐ standard orifice sidewall sprinklers” intended for use in fire sprinkler systems designed in accordance with the standard installation rules recognized by the ap- plicable Listing or Approval agency (e.g., UL Listing is based on NFPA 13 requirements)
Sprinkler Operation
During a fire conditions, the thermal‐sensitive liquid in the glass bulb expands, causing the bulb to shatter, releasing the button and spring seal assembly. Water flowing through the sprinkler ori- fice strikes the sprinkler deflector, forming a uniform spray pattern to extinguish or control the fire.
Coverage
For coverage area and sprinkler placement, refer to NFPA13 standards.
