Pair Cable (Networking Twisted Pair or Security/Alarm Pair), UTP/FTP/STP, PVC/LSZH/Plenum Jacket

Device Type: Twisted Pair Cable (Networking or Security/Alarm)
Brand/Model: Generic – specifications vary by category (e.g., Cat5e/Cat6 network cable vs. 2-pair/4-pair alarm cable). Verify the specific type and model on the physical unit.
Video Output: N/A (Copper signal cable for data or low-voltage control; not a video cable)
Data Ports: N/A (Bare cable; requires termination with connectors like RJ45 for networking or terminal blocks for alarm systems)
Conductor & Pair Specifications (Varies by Type):
Networking Twisted Pair (UTP/FTP):
Pair Count: Typically 4 pairs (8 conductors) for Ethernet networks.
Conductor Size: 22–24 AWG solid or stranded bare copper.
Impedance: 100 Ω ± 15%.
Categories: Cat5e (up to 100 MHz), Cat6 (up to 250 MHz), Cat6a (up to 500 MHz), Cat7/7a (up to 1000 MHz).
Alarm/Security Pair Cable:
Pair Count: Commonly 1 pair, 2 pair, 3 pair, or 4 pair.
Conductor Size: 18–22 AWG (e.g., 2-18 AWG, 2-22 AWG) stranded or solid bare copper.
Pairing: Conductors are twisted into pairs (e.g., Black & Red, Black & White) to reduce interference.
Shielding & Jacket:
Shielding Types (Networking):
UTP (Unshielded Twisted Pair): No shield; relies on twisting to cancel interference; most common for office environments.
FTP/STP (Foiled/Shielded Twisted Pair): Overall foil or braided shield; used in high-EMI environments.
S/FTP: Individual pair shielding plus an overall braid (highest protection).
Shielding Types (Alarm):
Unscreened: Standard indoor use.
Screened/Shielded: Aluminium/polyester foil with a drain wire; used in "noisy" environments.
Jacket Material: PVC (standard), FRPVC (flame-retardant), LSZH (Low Smoke Zero Halogen), or Plenum-rated (CMP/CL3P) for air-handling spaces.
Jacket Colour: Networking: Blue, Grey, White, Black. Alarm: Standard is Grey, other colours available.
Electrical & Environmental Characteristics (Typical):
Voltage Rating: Networking: Low-voltage data. Alarm/Security: 300 V (common) or signal-level.
Temperature Rating: −20°C to +75°C (varies by insulation/jacket).
DC Resistance (Alarm Example): Approx. 6.55 Ohm/1000 ft (for 18 AWG pair).
Capacitance (Alarm Example): Approx. 29 pF/ft (conductor-to-conductor).
Fire Ratings: Networking: CMR/CMG (riser), CMP (plenum). Alarm: CPR Eca, UL 1666 Riser, NEC Article 800.
Standards: Networking: TIA/EIA-568, ISO/IEC 11801. Alarm: UL 2464, IEC 60332, BS alarm cable references.
