Tyco Products 77-371-9-286 Pendent Sprinkler Head

Product Description

The TYCO PRODUCTS 77-371-9-286 is a quick response pendent sprinkler head designed for fire suppression systems. Built to the 286 series standard, this head uses a pendent orientation, meaning it hangs downward from the branch line and discharges water in a downward umbrella pattern when activated. The quick response classification indicates a faster thermal activation time compared to standard response heads, which is a code-driven requirement in many occupancy types. Licensed fire protection contractors and sprinkler fitters install this head as part of wet or dry pipe systems in commercial and residential applications.

This sprinkler head is suited for installation in suspended ceiling applications where pendent-style heads are required. The 286 series designation refers to the activation temperature rating, making this head appropriate for areas where ambient temperatures remain well below the activation threshold during normal operation. It is sold as a single unit and is intended for use in systems designed and installed per NFPA 13 or NFPA 13R guidelines by qualified fire protection professionals.

Key Features

• Quick response thermal element for faster activation compared to standard response heads
• Pendent orientation for downward discharge pattern in ceiling-mount applications
• 286 series activation temperature rating for standard ambient environments
• 1/2 inch orifice size for defined flow and coverage characteristics
• Single-unit sale allows targeted replacement without bulk ordering

Compatibility

Designed as an OEM-style replacement pendent sprinkler head for fire suppression systems requiring a 1/2 inch quick response pendent fitting in the 286 series temperature rating.

Installation Notes

Installation must be performed by a licensed fire protection contractor or certified sprinkler fitter in accordance with NFPA 13 or NFPA 13R and applicable local codes. The system must be taken out of service and pressure relieved before removing or installing any sprinkler head. Use only an approved sprinkler head wrench when installing to avoid damaging the deflector or frame. Never paint, coat, or modify the sprinkler head, as doing so can impair thermal response and void listing.
