Sky Vision Fire alarm 500m copper cable

A Security and Fire Alarm Cable is a low-voltage cable used for transmitting signals in fire detection, alarm systems, and security applications. It is designed to meet strict safety and fire-resistance standards.

1. Conductor
Material: Copper (Solid or Stranded)
Gauge (AWG): Common sizes include 12 AWG, 14 AWG, 16 AWG, 18 AWG, and 22 AWG
Number of Conductors: Typically 2 to 6, depending on the system requirements
2. Insulation
Material:
PVC (Polyvinyl Chloride) – Standard insulation for general use
FEP (Fluorinated Ethylene Propylene) – High-temperature resistance
Polyethylene (PE) – Used for enhanced durability and flexibility
Fire-Resistant Properties: Designed to withstand high temperatures and fire exposure
3. Shielding (Optional, Based on Application)
Unshielded (FPL, FPLR, FPLP) – Suitable for environments with minimal electrical interference
Shielded (FPLR-S, FPLP-S) – Reduces electromagnetic interference (EMI) in high-noise environments
Shield Types: Aluminum foil, braided copper, or Mylar
4. Outer Jacket
Material:
PVC (Standard use, cost-effective)
LSZH (Low Smoke Zero Halogen) for enhanced fire safety
Types:
FPL (General Purpose Fire Alarm Cable) – For basic applications, not for risers or plenums
FPLR (Riser-Rated Fire Alarm Cable) – Used for vertical runs in buildings (between floors)
FPLP (Plenum-Rated Fire Alarm Cable) – Used in plenum spaces (air-handling areas like ducts)
5. Voltage & Temperature Rating
Voltage Rating: Typically 300V (Power-Limited Applications)
Temperature Rating: Ranges from -20°C to 120°C, depending on insulation material
6. Fire Safety Standards & Certifications
UL 1424 – Standard for power-limited fire alarm cables
UL 1666 – Riser-rated fire-resistant cable standard
NEC (National Electrical Code) – Compliance with fire and electrical safety regulations
NFPA 70 & 72 – Fire alarm and emergency system codes
RoHS Compliance – Ensures environmentally safe materials
7. Applications
Fire alarm systems (smoke detectors, alarm panels, sirens)
Security systems (motion detectors, door contacts, keypads)
Access control systems (electronic locks, keycard readers)
Intercom and PA (Public Address) systems
CCTV and Surveillance systems
