A four-core alarm cable contains four insulated copper conductors, typically color-coded for easy identification. The conductors are made of stranded copper to maintain flexibility and reduce breakage during installation. These wires are bundled together and wrapped in a protective PVC outer sheath, which offers basic resistance to abrasion and environmental factors.

Typical Features

• 4 x 7/0.2 mm or 4 x 0.22 mm² stranded copper cores (common sizes)

• Color-coded insulation (e.g., red, black, yellow, blue or similar)

• PVC sheath for indoor installations

• Designed for low-voltage, low-current circuits

• Flexible and easy to route through walls or trunking

Common Uses

• Alarm control panels to sensors (PIRs, door contacts)

• Keypads and internal sounders

• Low-voltage signaling in automation or security systems

Why 4 Cores?

Four conductors allow:

• Power pair (positive and negative)

• Signal pair (trigger, tamper, or data depending on device)
