Why London contractors choose ValveAtlas fire department connections

UL 405 and FM 1530 dual listing for LFB acceptance. Every FDC we supply is UL 405 Listed (Fire Department Connections for Fire-Protection Service) and FM Class 1530 Approved. LFB accepts listed FDCs with factory submittal, ADB and BS 9990 compliance letter and NFPA 14 documentation. UL 405 certifies the FDC body, internal clapper check valves, swivel inlets, plug/cap and drain provisions.

Integral clapper check for backflow prevention. UVFDC-2W and UVFDC-3W include internal spring-loaded clapper check valves on each inlet that prevent backflow from the standpipe or sprinkler system through an unused inlet. NFPA 14 requires each FDC inlet to have a clapper check. The clapper is bronze with stainless spring, rated 300 psi working, 600 psi hydrostatic.

Brass or rough chrome finish with break-off cap chains. UVFDC bodies are cast red brass (ASTM B584) standard, rough chrome or polished chrome on request. Each inlet comes with a bronze plug or cap on a chain (break-away chain on sidewalk FDCs) to prevent debris ingress. Identification plate cast into body with “FIRE DEPARTMENT CONNECTION – STANDPIPE”, “AUTO SPKR” or “AUTO SPKR AND STANDPIPE” per NFPA 14/13.

Swivel inlets with LFB-compatible thread. UVFDC-2W and UVFDC-3W inlets are female swivel with BS 336 2.5 inch instantaneous round male coupling for standard 2-way and 3-way inlets per LFB spec. Storz 70 mm and 100 mm quick-connect inlets optional; LFB default is BS 336 instantaneous. Thread form is specified per factory order to match local fire department apparatus hose couplings. Swivel allows 360-degree rotation for fire department hose engagement at any angle.

Check valve integral with FDC body. NFPA 14 and NFPA 13 require a listed check valve between the FDC and the standpipe or sprinkler system. UVFDC bodies include integral main clapper check downstream of the inlet clappers to prevent system water egress through the FDC during testing or inspection. Combined UL 405 listing covers both inlet clappers and main check.

Code and listing acceptance for London

Building Regulations Approved Document B (ADB) 2019 and BS 9990. Building Regulations Approved Document B (ADB) 2019 and BS 9990 references NFPA 14 (standpipe FDC) and NFPA 13 (sprinkler FDC) for combined-system FDC placement. Per NFPA 14, the FDC shall be located not less than 18 inches and not more than 48 inches above grade and shall be visible and accessible to the fire department within 100 ft of a fire lane or paved access.

NFPA 14 standpipe FDC. NFPA 14 requires one 2.5 inch inlet for every 250 gpm of standpipe flow, minimum 2 inlets for Class I and III standpipes, with integral listed check valve between FDC and standpipe riser. Storz connection permitted with LFB approval. UVFDC-2W meets minimum requirement; UVFDC-3W provides additional capacity for high-rise Class I/III systems.

NFPA 13 sprinkler FDC. NFPA 13 requires an FDC for sprinkler systems with a water demand of 250 gpm or greater, with minimum 2-way 2.5 inch NH inlets and integral check valve between FDC and sprinkler riser. UVFDC-2W and UVFDC-SIDE-2W satisfy NFPA 13 requirement for exterior-accessible FDC upstream of sprinkler riser check valve.

UL 405 Fire Department Connections. UL 405 governs FDC body, clapper check valves, swivel inlets, plugs/caps and drain construction. UVFDC series meets UL 405 with bronze body, spring-loaded bronze clapper, NH or Storz inlet with thread gauge certification and break-chain cap. UL 405 required for all NFPA 13/14 applications.

FM 1530 approval. FM 1530 covers fire department connections. The UVFDC series carries FM Class 1530 approval for standpipe, sprinkler and combination systems per FM Data Sheet guidance on water supply.

LFB acceptance. London Fire Brigade (LFB), local water undertakers and UK insurers inspection references Building Regulations Approved Document B (ADB) 2019, BS 9990, NFPA 14 and manufacturer listing. Factory submittal with UL 405/FM 1530 certificates, NFPA 14/13 compliance letter and hydrostatic pressure test report required for sign-off. FDC sign identification per NFPA 14 required at the installation.

Approved-equal submittals

Where a specification names a specific manufacturer, we prepare an approved-equal submittal package (listing certificates, dimensional drawings and material data) for review by the engineer of record and the authority having jurisdiction.

Frequently asked questions (London)

Are these FDCs accepted by LFB? Yes. The UVFDC series is UL 405 Listed and FM 1530 Approved. LFB accepts listed FDCs with factory submittal, ADB and BS 9990 compliance letter, NFPA 14 documentation and hydrostatic test report. Sign identification per NFPA 14 required on the installation.

2-way vs 3-way FDC for London? 2-way (UVFDC-2W-2.5) satisfies minimum NFPA 14 requirement for Class I/III standpipes up to 500 gpm and NFPA 13 sprinkler systems. 3-way (UVFDC-3W-2.5) provides additional capacity for high-rise systems over 500 gpm or combined standpipe/sprinkler where engineer specifies extra inlet per NFPA 14.

Storz vs threaded inlets? Threaded (UVFDC-2W, UVFDC-3W) uses BS 336 2.5 inch instantaneous round male coupling for standard 2-way and 3-way inlets per LFB spec, compatible with existing LFB threaded hose. Storz (UVFDC-STZ4-W, UVFDC-STZ5-W) uses 4 inch or 5 inch quick-connect with sexless coupling, allows rapid connection without threading but requires LFB Storz spanner. Storz 70 mm and 100 mm quick-connect inlets optional; LFB default is BS 336 instantaneous.

Wall vs freestanding vs flush sidewalk? Wall-mount (UVFDC-2W, UVFDC-3W) is standard for buildings with exterior wall frontage. Freestanding (UVFDC-2W-FS) on pedestal post is required where wall mount is impossible (parking garages, set-back buildings, interior courtyards). Flush sidewalk (UVFDC-SIDE-2W) is required for narrow frontage where wall and pedestal are both impractical, with hinged cover plate to match sidewalk finish.

What is the pressure rating? Standard UVFDC is 300 psi working pressure with 600 psi hydrostatic test per UL 405. High-pressure option UVFDC-HP rated 400 psi working for industrial high-pressure loops. Internal clapper check rated same pressure class as body.

What is the delivery time to London? Stock UVFDC-2W-2.5 with standard NH thread ships 2 to 3 weeks. Custom thread forms (Quebec, NYC, Boston, Storz) factory-built 3 to 5 weeks. Freestanding UVFDC-2W-FS with pedestal 4 to 6 weeks. Flush sidewalk UVFDC-SIDE-2W 4 to 6 weeks. Metro freight from Toronto HQ 3 to 5 business days.
