Shipping calculated at checkout
The Reliable F1FR56-300 QREC RA3045 is a quick-response extended-coverage concealed pendent fire sprinkler engineered for commercial wet fire suppression systems. Installed flush within a finished ceiling using a factory-assembled sprinkler and cup combination, this unit activates via a 3 mm glass bulb thermal element to deliver rapid fire suppression across light-hazard occupancies. The required Model CCP conical cover plate is sold separately to complete the architectural concealment.
This fire protection assembly complies with NFPA 13 installation standards for light-hazard occupancies, satisfying code requirements for extended-coverage quick-response (QREC) protection. Contractors must verify specific coverage areas, flow requirements, and pressure parameters against Reliable Bulletin 030 and local Authority Having Jurisdiction (AHJ) guidelines prior to installation.
