Why 2/4/6 Core Fire Alarm Cable Is the Industry Standard
Fire alarm systems use a small set of standard core counts because every device has predictable wiring needs. 2/4/6 core fire alarm cable covers virtually all fire detection and notification devices - from a simple 2-wire addressable loop to a 6-core sounder-beacon combination. Using standard core counts simplifies installation, reduces inventory and ensures colour-coded consistency across a project.
Standard Core Counts
2, 4 and 6 cores cover 90% of fire alarm devices.
01
Colour-Coded Cores
Fast identification of loop, power, return and tamper circuits.
02
Addressable & Conventional
Works with both 2-wire loops and multi-core zone systems.
03
Stranded OFC
Flexible, low-resistance copper for reliable loop monitoring.
04
Core Count Selection Guide - 2, 4 or 6 Cores?
The right core count depends on the device. The three cards below explain when to use each:
2 Core Fire Alarm Cable - Loop & Zone Circuits
The 2 core fire alarm cable is the backbone of addressable fire alarm systems. It carries the 2-wire data loop that connects the panel to all addressable devices (smoke detectors, heat detectors, MCPs, sounders) on a single twisted pair. It is also used for simple conventional zone circuits where one cable runs through all detectors on a zone.
Uses: Addressable loop, conventional zone, short sounder circuit
Coins: 2 (loop + / loop −, or zone + return)
AWG: 18 / 20 / 22 AWG
4 Core Fire Alarm Cable - Detectors & Manual Call Points
The 4 core fire alarm cable is the most common size for individual fire detection devices. It provides two conductors for the detection circuit and two for tamper/auxiliary, or power and return for conventional detectors with sounder bases. It is also used for manual call points (break-glass stations) that need a supervised circuit.
Uses: Smoke detector, heat detector, MCP, combined detector
Coins: 4 (e.g. zone, tamper, +V, return)
AWG: 18 / 20 / 22 AWG
6 Core Fire Alarm Cable - Sounders, Beacons & Combined Units
The 6 core fire alarm cable handles notification appliances and combined detector-sounder units that need separate power, trigger, tamper and auxiliary circuits. It is also used for addressable sounder-beacon bases that draw more current and need dedicated conductors.
Uses: Sounder, beacon, sounder-beacon base, combined detector-sounder
Coins: 6 (e.g. +V, 0V, trigger, tamper, aux, spare)
AWG: 16 / 18 / 20 AWG
Fire Alarm Device Connection Table - Which Core Count for Which Device
Use this table to quickly match each fire alarm device to the correct 2/4/6 core fire alarm cable:
| Device | Recommended Cores | Core Functions | System Type | ||
| Addressable Smoke Detector | 2 Core | Loop + / Loop − (data + power) | Addressable | ||
| Addressable Heat Detector | 2 Core | Loop + / Loop − (data + power) | Addressable | ||
| Addressable Manual Call Point | 2 Core | Loop + / Loop − | Addressable | ||
| Conventional Smoke Detector | 4 Core | Zone, return, tamper, aux | Conventional | ||
| Conventional Heat Detector | 4 Core | Zone, return, tamper, aux | Conventional | ||
| Manual Call Point (conventional) | 4 Core | Contact, contact return, indicator LED, LED return | Conventional | ||
| Sounder / Horn | 6 Core | +V, 0V, trigger, tamper, spare, spare | Both | ||
| Sounder-Beacon Base | 6 Core | +V, 0V, sounder trigger, beacon trigger, tamper, aux | Addressable | ||
| Combined Detector-Sounder | 6 Core |

Quality Control & Testing
Every reel is 100% tested before shipment. For fire alarm cable, stable conductor resistance and insulation are critical for reliable loop and zone supervision. We test conductor resistance per IEC 60228 on every core, insulation resistance between every pair of cores, and high-voltage withstand between all cores and the sheath. A sample of each batch is retained for full traceability. Third-party inspection (SGS, BV, TÜV) welcome.
Conductor Resistance
IEC 60228 on every core - critical for loop accuracy.
Core-to-Core Insulation
Resistance tested between every core pair.
Batch Traceability
Sample retained per lot.
Typical Applications
This 2/4/6 core fire alarm cable is used for fire signalling wiring across various building fire safety systems.
Addressable Fire Systems
2-core loops for large commercial panels.
Conventional Fire Systems
4-core zones for small & medium buildings.
Smoke & Heat Detectors 2-core or 4-core drops to detector bases.
Manual Call Points 2-core or 4-core to break-glass stations.
Sounders & Beacons 6-core for notification appliances.
