4 Core Alarm Cable is a low-voltage, multi-strand cable used to wire up burglar alarms, intruder detection systems, and other basic security equipment. It's the entry-level option in the alarm cable range — simple, slim, and cost-effective for straightforward wiring jobs.
The cable contains 4 individual wires (cores) bundled together inside one outer sheath, each with its own colour. That's enough to carry, for example, power (+ and -) plus a signal wire and an earth/spare — a common setup for simple door contacts, single PIRs, or bell/siren connections.
| Feature | Typical Value | What it means for you |
|---|---|---|
| Number of cores | 4 | Enough for simple sensor/device wiring (power + signal) |
| Conductor material | Tinned copper (standard) or CCA (budget option) | Tinned copper resists corrosion and carries current more reliably — worth checking before you buy |
| Conductor size | Approx. 0.16mm² – 0.22mm² (approx. 24 AWG) | Fine enough for low-voltage signal/data use, not for mains power |
| Insulation/Sheath | White PVC (standard); other colours and LSF/LSZH available | LSF/LSZH releases less toxic smoke in a fire — often needed for commercial buildings |
| Overall diameter | Approx. 3.5mm – 3.8mm | The slimmest of the alarm cable range — easiest to route through tight conduit and cavities |
| Voltage rating | 50V – 300V depending on product (check datasheet) | Suitable for low-voltage alarm circuits only — not for mains electricity |
| Max current per core | Approx. 1 Amp (varies by product) | Sufficient for standard sensors, door contacts, and small sirens |
| Conductor resistance | Approx. 100–155 Ω/km | Lower resistance = better signal strength over longer cable runs |
| Operating temperature | -10°C to +80°C (varies by product) | Suitable for indoor and most loft space installations |
| Minimum bend radius | Approx. 10 × cable diameter | How tightly the cable can be bent around corners without damage |
| Standard/Approval | BS 4737-3.30 (UK Intruder Alarm Standard) | Confirms the cable meets recognised UK security-industry standards |
| Brand | Prestige |
| Category | Intruder alarm systems |
| Sub Category | N/A |
| Condition | New |
| Color | white |
