West Penn Wire DRS485DBBK1000 Shielded Fire Alarm Cable

Product Description

The WEST PENN WIRE DRS485DBBK1000 is a 22 AWG single-pair shielded solid conductor fire alarm cable supplied in a 1000-foot spool with a black jacket. Designed for low-voltage fire alarm and signaling circuits, this cable provides reliable signal integrity through its foil or braid shield construction, which reduces electromagnetic interference in installed runs. It is appropriate for use in commercial and residential fire alarm systems where shielded, solid-conductor cable is specified by the system designer or required by code. Licensed low-voltage and fire alarm technicians are the primary installers of this cable type.

This cable is suited for use in fire alarm control panel wiring, initiating device circuits, and notification appliance circuits where a 22 AWG shielded solid pair is called for. The 1000-foot spool length is appropriate for larger commercial jobs or stocking by fire alarm contractors. The black jacket color supports easy identification and is commonly accepted for in-wall and conduit runs in commercial fire alarm installations. Check local AHJ requirements before installation to confirm jacket and conductor ratings meet project specifications.

Key Features

• 22 AWG solid conductor construction for stable resistance and consistent signal transmission
• Single-pair configuration with overall shield for EMI and RFI reduction
• 1000-foot spool length suitable for commercial-scale fire alarm projects
• Black PVC jacket for identification and physical protection in conduit or plenum runs
• Fire shielded category rating consistent with fire alarm system wiring requirements

Compatibility

Designed as an OEM-style replacement and standard supply cable for low-voltage fire alarm and signaling systems requiring 22 AWG single-pair shielded solid conductor wire.

Installation Notes

Installation should be performed by a licensed low-voltage or fire alarm technician in accordance with NFPA 72 and applicable local codes. De-energize the fire alarm control panel and follow lockout-tagout procedures before making any connections. Route cable away from high-voltage conductors to minimize interference, and maintain minimum bend radius throughout the run to avoid damage to the shield or conductors. Consult the fire alarm system manufacturer and local AHJ for any additional installation requirements.
