8 Core Alarm Cable is a low-voltage, multi-strand cable used to wire up burglar alarms, intruder detection systems, access control, and other security equipment. Think of it as the "nervous system" of an alarm system — it carries power and signals between the control panel, sensors, keypads, sirens, and door/window contacts.
The cable contains 8 individual wires (cores) bundled together inside one outer sheath, each with its own colour. This means one cable run can carry several separate connections at once — for example, power to a sensor, a tamper circuit, and a signal wire — instead of running multiple single cables. This is why alarm cable is sometimes called "multicore" cable.
| Feature | Typical Value | What it means for you |
|---|---|---|
| Number of cores | 8 | Enough conductors for most standard alarm devices (power, signal, tamper, etc.) |
| Conductor material | Tinned copper (some budget options use Copper-Clad Aluminium/CCA) | Tinned copper resists corrosion and is more reliable long-term — worth checking before you buy |
| Conductor size | 0.15mm² – 0.22mm² (approx. 24 AWG) | Fine enough for low-voltage signal/data use, not for mains power |
| Insulation/Sheath | PVC (standard) or LSF/LSZH — Low Smoke (Zero Halogen) | LSF/LSZH options release less toxic smoke in a fire — often required for commercial or public buildings |
| Sheath colour | Usually white (black also available) | White blends into most walls and ceilings |
| Overall diameter | Approx. 4.4mm – 4.8mm | Compact enough to run through standard conduit and wall cavities |
| Voltage rating | 50V – 300V (check product datasheet) | Suitable for low-voltage alarm circuits only — not for mains electricity |
| Conductor resistance | Approx. 94–155 Ω/km | Lower resistance = better signal strength over longer cable runs |
| Operating temperature | -20°C to +80°C (varies by product) | Suitable for both indoor and most loft/roof space installations |
| Minimum bend radius | Approx. 65mm | How tightly the cable can be bent around corners without damage |
| Standard/Approval | BS 4737 (UK Intruder Alarm Standard), ISO 9001, UL758 | Confirms the cable meets recognised safety and performance standards |
| Brand | Prestige |
| Category | Intruder alarm systems |
| Sub Category | N/A |
| Condition | New |
| Color | White |
