Fire‑Alarm Speaker Cable ZRRVVP 2×1.5

Ordinary unshielded fire alarm cables have obvious defects in audio signal transmission scenarios. Without shielding protection, they are extremely susceptible to electromagnetic interference from power lines and weak-current integrated wiring, resulting in audio noise, current sound, sound distortion and unclear fire broadcast voice. Common non-flame-retardant audio wires fail fire safety standards, easily burning and spreading flames during fire accidents, causing paralysis of emergency broadcast systems. Low-grade cables adopt impure copper conductors with high resistance, leading to serious audio attenuation, insufficient speaker volume and poor sound quality after long-distance laying. Rigid single-core structure is prone to core breakage during repeated bending and corner routing, causing intermittent broadcast failure. Conventional cables lack anti-aging insulation protection and will crack or leak after long-term standby operation, bringing hidden dangers to fire emergency systems. The ZRRVVP Fire-Alarm Speaker Cable thoroughly solves the above industry pain points. Adopting professional RVVP overall shielding structure with aluminum foil shielding layer and tinned copper drain wire, it completely isolates external electromagnetic interference to ensure pure and distortion-free audio signals. High-purity multi-strand flexible oxygen-free copper conductor features low resistance and high conductivity, effectively reducing long-distance audio attenuation and maintaining consistent speaker volume and sound quality. ZR flame-retardant modified insulation and sheath achieve self-extinguishing and flame spread prevention, complying with building fire protection engineering standards. Soft stranded structure supports arbitrary bending and complex concealed wiring, adapting to long-term standby operation of fire broadcast systems without signal failure or circuit breakage.

This ZRRVVP shielded fire audio cable supports diversified personalized customization for building fire emergency broadcast systems, fire speaker matching circuits, public address sound transmission and fire linkage audio engineering projects. Full coverage shielding structure effectively filters electromagnetic crosstalk and current noise, realizing high-fidelity noise-free fire broadcast transmission without sound distortion. ZR flame-retardant safety grade prevents flame combustion and diffusion during fire incidents, ensuring emergency broadcast system can work normally in fire environments. Premium 2×1.5mm² large-section conductor reduces line resistance, perfectly solving long-distance audio attenuation and volume drop problems. Soft multi-strand flexible design offers excellent bending resistance, suitable for ceiling, pipeline and wall concealed wiring with complex turns. High-density anti-aging insulating sheath resists long-term temperature changes and insulation aging, extending system service life. Standard color separation and structured layout facilitate on-site construction and later circuit maintenance. Optional LSZH low-smoke zero-halogen upgrade meets high-standard environmental fire protection requirements. According to project demands, we can customize sheath material, cable color, length specification and packaging to meet refined fire audio wiring standards.
