Globe Fire Sprinkler 443115503 Sidewall Sprinkler

Product Description

The Globe Fire Sprinkler 443115503 is a residential horizontal sidewall fire sprinkler designed for installation along walls in lieu of ceiling-mounted heads. This sprinkler carries a 4.4K flow coefficient and a 155 degrees F temperature rating, making it appropriate for ordinary-hazard residential applications where ceiling installation is not practical. The 1/2 inch male pipe thread (MPT) connection fits standard sprinkler branch lines. The white finish allows the head to blend with typical interior wall finishes. Installation is performed by a licensed fire protection contractor in accordance with NFPA 13D or 13R requirements.

This horizontal sidewall sprinkler is suited for residential occupancies including single-family homes, townhomes, and multi-family dwelling units. It mounts flush to or near the wall surface and distributes water in a half-parabolic pattern across the protected area. The 155 degrees F ordinary temperature classification covers standard living spaces where ambient temperatures remain well below the activation threshold under normal conditions.

Key Features

• 4.4K flow coefficient for predictable hydraulic performance in residential systems
• 155 degrees F ordinary temperature rating for standard residential environments
• Horizontal sidewall orientation for wall-mounted installation where ceiling placement is not feasible
• 1/2 inch MPT connection for compatibility with standard sprinkler branch line piping
• White finish for low-profile aesthetics in finished living spaces

Compatibility

Designed as an OEM-style replacement or new-installation residential horizontal sidewall sprinkler head for NFPA 13D and 13R compliant fire suppression systems with hydraulic designs calling for a 4.4K coefficient head at the 155 degrees F temperature rating.

Installation Notes

Installation must be performed by a licensed fire protection contractor in compliance with NFPA 13, 13D, or 13R and all applicable local codes. Shut down and depressurize the fire suppression system before removing or installing any sprinkler head. Use only an appropriate sprinkler wrench on the sprinkler wrench boss — do not grip the deflector or frame during installation, as deformation will void listing and impair water distribution. Inspect the installed head for leaks during system recommissioning.
