West Penn Wire 303GY1000 Shielded Security Cable 18AWG 3C

Product Description

The WEST PENN WIRE 303GY1000 is an 18 AWG, 3-conductor stranded shielded cable rated CMR (riser) for use in low-voltage security, access control, and alarm wiring applications. The stranded conductor construction provides flexibility during pull and termination, while the overall shield helps reject electromagnetic interference common in commercial building environments. This 1000-foot reel is sized for larger installations and is suitable for in-wall and plenum-adjacent riser runs where a CMR rating meets code. Security integrators and low-voltage technicians are the primary installers.

This cable is used in commercial and residential security system installations including intrusion detection panels, access control readers, door contacts, motion detectors, and similar low-voltage devices. The gray jacket is standard for security wiring in commercial environments and allows easy identification in conduit or bundled runs. The CMR riser rating makes it appropriate for vertical runs between floors where fire code requires riser-rated cable. The 1000-foot length suits structured wiring contractors and service companies stocking for multiple jobs.

Key Features

• 18 AWG stranded conductors for flexibility and ease of termination
• 3-conductor configuration for security and alarm device wiring
• Overall shield reduces EMI and signal interference in busy electrical environments
• CMR riser rating meets NEC requirements for vertical inter-floor cable runs
• Gray PVC jacket for standard security industry color identification
• 1000-foot reel quantity suited for commercial installation projects

Compatibility

Designed as an OEM-style replacement and standard-stock cable for low-voltage security, access control, and alarm wiring systems requiring 18 AWG 3-conductor shielded CMR-rated cable.

Installation Notes

Installation should be performed by a licensed low-voltage technician or security system integrator in accordance with NEC Article 725 governing Class 2 and Class 3 remote-control and signaling circuits. De-energize and lock out all connected panels and power supplies before making terminations. Maintain minimum bend radius during pulls to avoid damaging the shield or conductor insulation. Do not exceed the voltage and current ratings of the connected devices or panel terminals.
