The product is a "Reliable Fire Sprinkler Horizontal K4.2 GFR Model R3133".
From the search results, I can gather the following:
-
Model: R3133.
-
Series: GFR (Globe Fire Resistant - often implies glass bulb, though some results mention fusible alloy link for GFR, but R3133 is consistently described as using a fusible alloy link. The "glass bulb activating at 165F with a 4.2 K-Factor" is mentioned for R3133 in, but also "fusible alloy link operating element". I'll prioritize fusible alloy link as it's more consistently mentioned for the GFR series as a whole and the R3133 specifically in the context of advanced quick response).
-
K-Factor: 4.2 (US) / 60 (Metric). This is a low K-factor, suitable for light hazard occupancies.
-
Orientation: Horizontal Sidewall. This means it's mounted on walls, not ceilings. It sprays in a quarter-spherical or half-circle pattern.
-
Response Type: Quick Response (QR). Described as "approximately five times faster than standard response sprinklers". Some sources say "five times faster than quick response sprinklers" which seems contradictory. I will stick to "quick response" and emphasize its speed compared to *standard response*.
-
Operating Element: Fusible alloy link.
-
Thread Size: 1/2" NPT.
-
Max Working Pressure: 175 psi (12 bar).
-
Listings/Approvals: cULus Listed. NFPA 13, 13D, 13R compliant.
-
Finishes: Available in various finishes, with chrome specifically mentioned for R3133.
-
Temperature Ratings: Often available in multiple temperatures; 165°F (74°C) is a common one mentioned for R3133.
-
Applications: Residential, commercial, light hazard occupancies, hotel rooms, corridors, offices, apartments, where ceiling piping is impractical or undesirable.
-
Spray Pattern: Projects water outward in a quarter-spherical or half-circle spray pattern. Now, I'll structure this information according to the user's requested format and SEO guidelines.
H1 Heading: Focus on quick response, reliability, and horizontal sidewall.
Introduction: Summarize what it is, who it's for, and its main appeal (rapid, discrete protection).
Key Features: List specific technical details and design aspects.
Benefits: Explain *why* these features matter to the user (safety, compliance, aesthetics, reduced damage).
Keywords to integrate: Reliable Fire Sprinkler, Horizontal Sprinkler, K4.2, GFR, R3133, Quick Response, fire protection, sidewall mounting, light hazard, automatic sprinkler, fire safety, code compliance, residential, commercial. Let's refine the "GFR" meaning. While some Reliable GFR sprinklers use glass bulbs, the R3133 specific model is consistently noted with a "fusible alloy link operating element". So, "GFR" in this context refers to the series name, and the specific activation mechanism for R3133 is the fusible link. I should avoid using "Globe Fire Resistant" as it could be misleading if it implies a glass bulb. I will focus on "GFR Series" and the "fusible alloy link." The claim "five times faster than quick response sprinklers" seems like a typo in the sources and likely means "five times faster than *standard* response sprinklers," which is a common quick response claim. I will rephrase to avoid this contradiction. "demonstrated response times... much faster than standard response sprinklers". Or "approximately five times faster than conventional quick response sprinklers" - this is also a bit confusing. I will focus on "rapid response" and "quicker than standard response." Source says "five times faster than conventional quick response sprinklers" which is very high praise if true. I'll go with a safer "rapid response, significantly faster than standard sprinklers". Let's check the product title for "GFR": "Reliable Fire Sprinkler Horizontal K4.2 GFR Model R3133". So "GFR" is part of the product identity. I will use it as the series name. Confidence Score: 5/5 - I have enough information from the search results to create a comprehensive and accurate description.
Strategizing complete. I will now generate the response.
