The TruSound 14\/4 achieves a B2ca-s1a, d1, a1 CPR classification under EN50575:2014+A1:2016, one of the highest Euroclass fire ratings available for cables under the Construction Products Regulation (CPR).\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eB2ca indicates extremely limited flame spread and minimal heat release in the event of a fire. The additional classifications are equally important: s1a denotes very low smoke production, d1 indicates no flaming droplets or particles, and a1 confirms minimal acidity of combustion gases. Combined with its Low Smoke Halogen Free (LSHF) construction, the TruSound 14\/4 produces minimal smoke and releases no toxic halogen gases in a fire situation — helping to maintain safe evacuation routes and limiting damage to sensitive equipment and building infrastructure.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eEngineered for Professional Fixed Installations\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe TruSound 14\/4 has been engineered specifically for permanent installation in walls, conduits, ceiling voids and risers across a wide range of commercial and public sector projects. The 4-core 2.5mm configuration makes it an ideal choice for installations requiring additional circuit capacity — such as bi-amplified speaker systems, dual-zone 100V line distributions or low impedance installations where heavier gauge conductors are needed to minimise signal loss over longer cable runs. The stranded oxygen-free bare copper conductors ensure excellent signal conductivity and long-term reliability, whilst the dual-layer Low Smoke Halogen Free insulation and sheathing provide robust mechanical protection alongside the cable's exceptional fire performance credentials.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe distinctive violet sheath makes the TruSound 14\/4 immediately identifiable on site and within installation pathways — a practical benefit for installers and maintenance engineers working within complex multi-cable building environments. The four cores are identified by Red, Blue, Black and White colour coding for straightforward and consistent termination throughout the installation.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eCompliance You Can Rely On\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe TruSound 14\/4 carries a comprehensive suite of compliance certifications to give contractors, specifiers and building control professionals complete confidence in the product. In addition to its B2ca CPR classification, the cable is compliant with BS EN 60332-1-2 for flame retardancy, BS EN 61034-2 for low smoke generation and BS EN 60754-1\u0026amp;2 for halogen gas emission. It is RoHS and CE compliant under LVD (2014\/35\/EU) and CPR (305\/2011), and has been UV and weather tested to ISO 4892-3 for reliable performance in exposed installation environments. The cable carries a voltage rating of 450\/750V and has been test voltage rated at 2.5kV for 5 minutes.\u003c\/p\u003e\n\u003ch3 data-end=\"1057\" data-start=\"1014\"\u003eTruSound TSS02504H06-B204 Key Features:\u003c\/h3\u003e\n\u003cul data-end=\"1612\" data-start=\"1058\"\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eB2ca-s1a, d1, a1 CPR Rated:\u003c\/strong\u003e Achieves one of the highest Euroclass fire ratings for cables under EN50575:2014+A1:2016, meeting the most stringent fire safety requirements for public and commercial buildings.\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eLow Smoke Halogen Free (LSHF):\u003c\/strong\u003e Both insulation and sheath are LSHF rated, producing minimal smoke and no toxic halogen gases in the event of a fire to maintain safe evacuation routes.\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eStranded Oxygen-Free Bare Copper Conductors:\u003c\/strong\u003e High-purity OFC conductors for excellent signal conductivity, low resistance and long-term reliability in permanent installations.\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003e4-Core 2.5mm (14AWG) Construction:\u003c\/strong\u003e Ideal for bi-amplified speaker systems, dual-zone 100V line distributions and low impedance installations requiring heavier gauge conductors over longer cable runs.\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eDistinctive Violet Sheath:\u003c\/strong\u003e Easily identifiable on site and within cable pathways for straightforward maintenance and identification.\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eRed, Blue, Black \u0026amp;
