18/2 fire alarm cables typically fall into the category of specialized cables designed for fire alarm systems. The “18/2” in its name denotes its construction, which has 18-gauge conductors and two conductive paths. It is a thinner construction than the 14 and 16/2 fire alarm cables. The conductors are usually made of solid bare copper, which provides efficient electrical conductivity. The electrical wire is insulated with fire-safe materials (usually PVC or LSZH) and shielded with aluminum foil to limit the emission of smoke and toxic gases in the event of a fire.

Application

18/2 Fire Alarm Cable has excellent resistance to fire and high temperatures. It is suitable for low voltage applications in fire alarm systems, including signaling and control circuits. It is also widely used in a variety of fire protection systems, anti-theft systems, smoke control systems and communication systems such as emergency voice evacuation systems.

Construction

• Conductor: Plain annealed copper Class 1
• Insulation: FR-PVC (Polyvinyl Chloride)
• Shielding: Aluminum foil
