This 12 core direct burial alarm cable is designed for external installations where the cable is installed underground without additional ducting. It uses stranded tinned copper conductors for flexibility and corrosion resistance, with a water-resistant PE outer sheath to withstand moisture and soil conditions.
Typically used for external runs between buildings, gate and perimeter security systems, outbuildings, and buried connections for intruder alarms, access control, intercoms and other low voltage signalling systems. The screened construction helps reduce interference in environments where cables are routed alongside power or external services.
The robust black PE sheath provides mechanical protection and moisture resistance, making it suitable for direct burial applications in commercial, residential and site installations.
