UL 405:2020 PDF Download

The UL 405:2020 standard pertains to devices and roof manifolds used in buildings that have standpipe and hose, water spray, or sprinkler systems. These devices are specifically designed to allow fire departments to connect hose lines directly to these systems, thereby supplementing existing water supplies.

The standard outlines the requirements for the installation and use of fire department connection devices and roof manifolds for fire protection service. It also references other relevant standards of the National Fire Protection Association (NFPA), including NFPA 13 (Installation of Sprinkler Systems), NFPA 14 (Standpipe, Private Hydrants, and Hose Systems), NFPA 15 (Water Spray Fixed Systems for Fire Protection), and NFPA 24 (Installation of Private Fire Service Mains and Their Appurtenances). Compliance with these standards ensures the proper functioning and effectiveness of fire department connection devices in fire protection systems.
