• 【True Gauge 18 AWG – 2 Conductors with 7-Strand Bare Copper】This 18/2 security wire has two stranded conductors made of 100% bare copper, each with seven strands approximately 0.39 mm in diameter. Maximum DC resistance per conductor is 6.68 ohms per 1,000 ft at 20°C, meeting the specification requirements for 18 AWG stranded copper conductors. This helps limit voltage drop and supports reliable low-voltage security and control operation.
• 【Shielded Cable with Tinned Copper Drain Wire】An aluminum foil shield with PET backing helps reduce external EMI/RFI interference in low-voltage signal wiring. A 24 AWG stranded tinned copper drain wire provides a convenient shield termination connection. This 18/2 shielded wire supports security alarm and control installations where shielding is required. Connect the drain wire according to the equipment’s shielding and grounding instructions.
• 【ETL Listed to UL 13 – CL3P Plenum Rated】This 18 AWG cable is ETL Listed to UL 13 as a power-limited circuit cable and carries a CL3P plenum rating for installations requiring limited flame spread and smoke generation. Suitable for permitted indoor plenum and in-wall security wiring. Rated 300V for power-limited circuits
• not intended for AC mains wiring or mains power cords. Operating temperature: -20°C to +75°C.
• 【For Security Alarms, Door Contacts & Low-Voltage Control】Designed for compatible 0–30V circuits, this 18/7 low voltage wire connects door and window contacts, alarm zones, and compatible two-wire alarm sensors. It also serves signal and contact circuits in access control systems. Match the two-conductor configuration, wire gauge and cable length to the equipment’s current, voltage-drop and wiring requirements.
• 【Color-Coded Conductors + Installation Kit Included】Red and black conductor insulation helps identify connections, while the white PVC jacket includes a ripcord for easier jacket removal. The approximately 4.2 mm cable diameter helps with routing in tight spaces. Each package includes 10 wire nuts, 1 roll of PVC electrical tape and an ETL certificate for convenient installation preparation.
