4 Core Fire Alarm Cable - For Fire Detection and Alarm Systems
 

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.

Frequently Asked Questions

 

Q: What is 4 core fire alarm cable used for?

A:4 core fire alarm cable is the most common configuration for wiring fire detection and alarm systems. Two cores carry the addressable loop or conventional zone circuit to detectors and call points, and the remaining two cores provide power to sounders, remote outputs or a tamper/monitor pair. It is the standard cable between a fire alarm control panel and a zone of detectors or sounders in residential, commercial and industrial buildings.

Q: Why is 4 core the standard for fire alarm wiring?

A: A fire alarm device typically needs two functions: a signal/communication pair and a power (or tamper) pair. 4 core gives you exactly that in one cable, with no spare pair wasted and no second cable to pull. It matches the standard L1, L2, S, V wiring designations in BS 5839-1 (one pair for the loop, one pair for sounder/control). For pure sounder circuits a 2-core cable is enough; for combined detector+sounder wiring a 4-core cable is the standard.

Q: Does 4 core fire alarm cable need to be red?

A: Red is the standard jacket colour for fire alarm cable in most markets because it gives instant visual identification of life-safety wiring that must not be cut or repurposed. In some jurisdictions white or cream is also accepted for fire alarm cable installed in concealed locations where red would be visually intrusive. We supply both red (standard) and white 4 core fire alarm cable.

Q:What is the difference between LSZH and fire-resistant 4 core fire alarm cable?

A: LSZH (low smoke zero halogen) cable resists flame spread and produces little smoke and no corrosive halogen gas in a fire, but it does NOT keep working once the fire reaches it. Fire-resistant (PH30/60/120) cable uses a mica-glass tape layer over the conductor so the circuit keeps carrying current for 30, 60 or 120 minutes into the fire. Fire-resistant cable is mandatory for circuits that must survive a fire - sounder circuits, evacuation lifts, smoke extraction. LSZH is sufficient for general detector and zone wiring.

Q: What standards does 4 core fire alarm cable comply with?

A:Our 4 core fire alarm cable is manufactured to BS 5839-1 (UK fire alarm system standard) for installation practice, EN 54 (European fire detection product standard), NFPA 72 (US fire alarm code), IEC 60331 (circuit integrity under fire) for fire-resistant grades, and CPR EN 50575 for fire performance of the jacket. The conductor meets IEC 60228 Class 5.

Q:What is the MOQ and lead time for 4 core fire alarm cable?

A:MOQ is 10000 m for standard 4 core fire alarm cable and fire-resistant (PH30/60/120) or custom print. Lead time is 25–30 working days for bulk OEM orders, with samples available in 5–7 working days.
