Jiaxing Doublewin Cable Co., Ltd. is one of the most reliable manufacturers and suppliers of 4 core fire alarm cable in China. If you're going to wholesale bulk 4 core fire 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.
4 core fire alarm cable consists of four insulated conductors built for fire detection, alarm, monitoring and control circuits. The four conductors support multiple wiring layouts defined by fire alarm equipment manufacturers and project designers. Select conductor material, cross-sectional area, insulation, shielding and outer sheath according to electrical demands and installation environment.
Our fire alarm cables deliver distinct performance grades: flame retardant, low smoke halogen-free and fire-resistant. These performance categories cannot be interchanged. Flame-retardant cable restricts flame spread under defined test criteria. Fire-resistant cable preserves circuit integrity for a set duration during fire exposure. Low-smoke halogen-free construction controls smoke emission and eliminates corrosive halogen gas release. To select the proper 4 core fire alarm cable, confirm the applicable standard, cable classification, installation environment and full project specifications.
As a direct manufacturer, we evaluate your technical requirements and match the correct cable construction using our in-house production capacity.


Key Features of 4 Core Fire Alarm Cable
1.Four-Core Conductor Configuration
The four-conductor design supports fire alarm and monitoring system wiring. Define conductor quantity, cross-section, material and colour coding to match system design and installation standards.
2. Insulation and Outer Sheath Options
Choose insulation and sheath materials based on approved cable design and site environment requirements. Our available materials include PVC and LSZH compounds for different project specifications.
3. Flame-Retardant Cable Options
Our flame-retardant cables meet defined flame propagation standards. Verify flame performance via the corresponding test standard and finished cable sample. Material names alone cannot determine flame performance.
4. Fire-Resistant Cable Options
Certain fire alarm circuits demand fire-resistant cable that maintains circuit integrity for a fixed duration under fire test conditions. Fire resistance relies on the full cable structure and relevant certification requirements. This performance is independent of standard flame-retardant properties.
5. Shielding Options
Use shielded cable constructions for projects requiring electromagnetic interference protection. Available designs include foil shielding, braided shielding and drain wire, as defined in the approved specification.
6. Custom Manufacturing
We offer custom manufacturing covering conductor gauge, insulation, shielding, outer sheath, cable colour, surface marking and packaging, subject to our production capacity.

Why 4 Core Is the Workhorse of Fire Alarm Wiring
A fire alarm system has two electrical jobs: detect the fire (detectors, call points) and warn the occupants (sounders, strobes). Most field devices need both a signal circuit and a power circuit, which is exactly what a 4 core fire alarm cable delivers in a single pull - two cores for the addressable loop or conventional zone, two cores for the sounder power, remote indicator or tamper/monitor return. The 4-core layout matches the standard L1, L2, S, V wiring designations of BS 5839-1, which is why it is the single most-specified configuration in residential, commercial and industrial fire alarm installations. Using one 4-core cable instead of two 2-core cables halves the pulling time, halves the conduit fill, and removes the risk of mixing up the two circuits on a crowded site.

Why Buy 4 Core fire Alarm Cable From Doublewin?
4-Core Power + Signal
Two conductors for 24 V DC power, two for the addressable loop - a single cable run delivers both to every smoke detector, call point and sounder.
Tinned Copper Conductors
Tinned plating resists corrosion in damp or condensing environments, extends cable lifetime and ensures reliable signal contact for decades.
LSZH Low-Smoke Zero-Halogen
When the fire alarm cable itself is the source of the fire, LSZH burns with minimal smoke and no toxic halogens - essential for tunnels, hospitals and high-rises.
Shielded or Unshielded
Aluminium-foil (FL) or braided-copper (SB) shielding on request for installations near power cables, motors or radio-frequency equipment.
