Device Type: 4-Core Security / Alarm Cable (Low Voltage)
Video Output: N/A (Low-voltage signal cable for sensors and control panels)
Data Ports: N/A (Hardwired connection; typically stripped and terminated into alarm panel terminals or detectors)
Conductor & Core Specifications (Typical Range):
Core Count: 4 cores
Conductor Size: Common sizes include 0.22 mm² (24–25 AWG) for standard signal wiring and 1.0 mm² for fire-rated or higher-power circuits.
Conductor Material: Varies by grade:
Bare Copper: Standard for reliable signal transmission.
Tinned Copper: Offers corrosion resistance.
CCA (Copper Clad Aluminium) / CCAM: A cost-effective alternative used in budget cables.
Stranding: Typically 7-strand construction (e.g., 7×0.18mm, 7×0.16mm, or 7×0.185mm) to provide flexibility.
Core Colours: Standard colour code is Red, Blue, Yellow, Black.
Shielding & Jacket:
Shielding: Available in both Unscreened (for general indoor use) and Screened/Shielded (with aluminium foil and a drain wire) variants to protect against electromagnetic interference.
Insulation & Jacket Material: Common materials include PVC (standard), LSZH/LSHF (Low Smoke Zero Halogen, for fire safety), and PE (for outdoor/UV resistance).
Outer Diameter: Approximately 3.5 mm to 3.9 mm for standard 0.22mm² cables, depending on insulation and shielding.
Electrical & Environmental Characteristics:
Voltage Rating: Commonly 50V to 300V depending on the standard (e.g., BS4737 vs. fire-rated).
Temperature Rating: Typically ranges from -25°C to +70°C for standard PVC cables, and up to +90°C for fire-rated LSZH variants.
DC Resistance: Varies by conductor size (e.g., ≤27 Ω/100m for some CCA cables, ≤155 Ω/km for standard copper).
Fire Rating: Look for standards like BS 7629-1 (fire-resistant) or CPR Eca (flame retardant) for life-safety installations.
