Jiaxing Doublewin Cable Co., Ltd. is one of the most reliable manufacturers and suppliers of fire rated alarm cable in China. If you're going to wholesale bulk fire rated alarm cable made in China, welcome to get pricelist and free sample from our factory. All customized cables are with high quality and competitive price.
A fire rated alarm cable is the cable that still carries a detection signal while the compartment around it is burning. This one wraps every conductor in a mica-glass barrier, is tested to BS 6387 categories C, W and Z and to EN 50200, and is built in 2 and 4 core from 0.8 to 2.5 mm² - the format a BS 5839-1 designer calls up for detection loops, sounder circuits and manual call points. As a fire rated alarm cable manufacturer, Jiaxing Doublewin Cable Co., Ltd produces this cable in-house in Haiyan, Zhejiang, China and supplies it in bulk worldwide.

What BS 5839-1 Clause 26.2 Actually Asks of the Cable
BS 5839-1 does not name a cable. It names a performance, and it puts that performance in Clause 26.2. The clause requires that cable for fire detection and alarm circuits maintain circuit integrity for the period the system is expected to keep working, and it splits the requirement into two grades: standard grade, tested to BS 7629-1, and enhanced grade, tested to BS 8434-2.
In practice this is the single question that decides your bill of materials. Standard grade is tested for 30 minutes in a 950 °C flame with a water spray applied. Enhanced grade is tested for 60 or 120 minutes with fire, water and mechanical shock applied together. If your specification says only fire rated alarm cable, it has answered the material question and left the grade question open - and the grade is what costs money.

Why Fire Rated Alarm Cable Is Essential for Life Safety
In a fire, ordinary cable burns through and stops working within minutes - exactly when you need the alarm system most. Fire rated alarm cable maintains circuit integrity for 30, 60, 90 or 120 minutes, giving occupants time to evacuate and emergency services time to respond. A mica-tape barrier around each conductor keeps the copper insulated even as the polymer jacket burns away.

Mica Tape Fire Barrier - How Circuit Integrity Works
The secret to fire rated alarm cable is the mica-tape fire barrier. Mica is a mineral that does not burn and retains its insulating properties up to 1,000°C. When the polymer jacket and insulation burn away in a fire, the mica tape remains intact, keeping the copper conductors separated and the circuit alive.
Why Mica, Not Ceramic?
Some low-cost "fire rated" cables use ceramic filler instead of mica tape. Ceramic filler melts and drips at lower temperatures, losing insulation. Mica tape maintains its structure and insulation up to 1,000°C, which is why it is specified in EN 50200, IEC 60331 and UL 2196. All our fire rated cable uses genuine mica-tape wrap, not ceramic filler.
QUALITY CONTROL
The secret to fire rated alarm cable is the mica-tape fire barrier. Mica is a mineral that does not burn and retains its insulating properties up to 1,000°C. When the polymer jacket and insulation burn away in a fire, the mica tape remains intact, keeping the copper conductors separated and the circuit alive.
Conductor & Circuit Integrity Test
We conduct strict conductor and circuit integrity tests for every batch of fire rated alarm cable. These tests verify that the cable can keep working under high-temperature fire conditions, meeting BS5839 and BS6387 requirements for fire safety systems.
Fire & Insulation Performance Test
Our lab carries out fire resistance and flame retardant tests, plus concentricity and resistance inspection. All insulation materials are checked to guarantee stable electrical performance and fire protection capability in harsh environments.
Batch Traceability
Finished fire rated alarm cable reels are stored and managed with full batch traceability. Every production lot can be tracked, supporting quality inspection and project certification requirements for global construction and security projects.
Typical Applications
Our fire rated alarm cable preserves circuit integrity during fire emergencies. It ensures stable signal transmission for smoke detectors, heat sensors and fire alarm control panels. Designed to meet BS 6387 CWZ requirements, it is the ideal wiring solution for BS 5839 compliant fire alarm systems across a wide range of building projects.
Fire Alarm Systems
Addressable & conventional detection loops, manual call points.
Emergency Lighting
Maintained & non-maintained escape lighting circuits.
Smoke & Heat Ventilation Smoke control dampers, powered smoke vents.
Evacuation Systems Voice evacuation, disabled refuge, fire-fighter lifts.
High-Risk Buildings Hospitals, tunnels, metros, data centres, high-rises.
What We Can Show Your Inspector
Every production lot is routine-tested for conductor resistance, insulation resistance and high-voltage withstand. Separately from that, a sample from each lot goes for circuit-integrity testing against BS 6387 categories C, W and Z, and the retained sample stays in our store for 24 months. If your project needs a witnessed test, SGS, BV or TÜV can attend at our plant against a purchase order.
We do not print the words fire rated on a drum. Drums are marked with the standard, the category, the lot number and the conductor size, because that is what a site inspector reads.
