BASIC USE:
Nelson PCS Pipe Choke Systems are prefabricated devices used to seal penetrations and restore the fire rating to floors or walls in which openings have been made for the passage of nonmetallic pipes. When exposed to fire the intumescent material will expand to seal voids caused by deteriorating nonmetallic pipe, maintaining the seal and preventing the passage of fire or smoke to adjacent areas.
COMPOSITION AND MATERIALS:
Nelson PCS firestop device consists of a heavy gage metallic collar filled with a highly intumescent material and flush mounted to the wall or floor.
APPLICABLE STANDARDS:
UL 1479 Fire Tests of Through-Penetration Firestops. ASTM E-814, Fire Tests of Through-Penetration Fire Stops. ASTM E-119, Fire Tests of Building construction and Materials.
APPLICABLE CODES:
Nelson PCS meets the requirements of all three model building codes (National Building Code, Uniform Building Code, Standard Building Code), as well as the National Electrical Code, the Life Safety code, and most state and city codes. For specific approval information contact Nelson.
