1.0mm fire alarm cable

1.0mm fire alarm cable Construction:

• Conductor: Usually made of plain annealed copper wire, with options for different classes (e.g., Class 1, 2, or 5) according to EN60228.
• Insulation: Provides electrical insulation between the conductor and other components.
• Separator: Often a PET foil, acting as a barrier.
• Drain Wire: A solid tinned copper wire, often 0.80mm, to help with grounding and shielding.
• Shield: Typically includes an Aluminum PET layer with 100% coverage and 20% overlapping for electromagnetic interference (EMI) protection.
• Jacket: The outer layer, providing protection and often made of fire-retardant materials. 

• Fire Resistance:

  Designed to withstand fire conditions for a specified duration (e.g., PH30, PH60, PH120, according to BS EN 50200). 
• Low Smoke and Halogen-Free:

  Some versions are made with low smoke, zero halogen (LSZH) materials, crucial for public safety. 
• Standards:

  Commonly adhere to standards like BS 7629-1, BS EN 50200, BS5839-1, and BS5266. 
• Voltage Rating:

  Typically rated for 300/500V. 
• Bend Radius:

  A minimum bend radius (e.g., 8 times the diameter) is specified to prevent damage during installation. 
• Applications:

  Used in fire detection and alarm systems, emergency lighting, and voice communication circuits. 

Important Considerations:

• Circuit Integrity:

  The cable’s ability to maintain signal transmission during a fire is crucial for the proper functioning of the alarm system. 
• Proper Installation:

  Following recommended installation practices and standards is essential for optimal performance. 
• Environmental Considerations:

  Depending on the application, factors like temperature, humidity, and exposure to chemicals should be considered when selecting the cable type.
