Description
The BF001/BF005 Standard/Quick Response Upright and BF002/BF004 Standard/Quick Response Pendent.

Sprinklers (Ref. Figure A) are automatic sprinklers of the frangible bulb type. They are “standard/quick response – standard orifice spray sprinkler” intended for use in fire sprinkler systems designed in accordance with the standard installation rules recognized by the applicable Listing or Approval agency (e.g., UL Listing is based on NFPA 13 requirements). The Upright, Pendent Sprinklers all produce a hemispherical water distribution pattern be- low the deflector.

Coverage
For coverage area and sprinkler placement, refer to NFPA13 standards.

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 orifice strikes the sprinkler deflector, forming a uniform spray pattern to extinguish or control the fire.
