Installation Notes

This 22/4 riser security alarm bulk cable is specifically designed for vertical installations between floors in non-plenum spaces, such as riser shafts, elevator shafts, and vertical cable runs in walls. The CMR/CL3R rating ensures the cable meets fire safety requirements for these applications.

CMR/CL3R Riser Rating: The dual CMR/CL3R rating indicates:

• CMR (Communications Riser): Suitable for vertical runs per NEC Article 800
• CL3R (Class 3 Riser): Suitable for power-limited fire-protective signaling circuits per NEC Article 725
• Meets fire safety standards for riser applications
• NOT suitable for plenum spaces (use CMP-rated cable)
• Appropriate for vertical cable runs between floors

Solid vs. Stranded Conductors: This cable uses solid conductors (single continuous wire per conductor):

Advantages of Solid Conductors:

• Lower DC resistance: Better electrical performance over long runs
• Less signal attenuation: Superior for permanent installations
• Better high-frequency performance: Improved signal quality
• More durable for fixed installations: Won't fray or break from stationary installation
• Easier to punch down: Works better with 110 blocks and patch panels
• Cost-effective: Generally less expensive than stranded

When to Choose Solid:

• Permanent installations (in-wall, in-ceiling, fixed runs)
• Long horizontal or vertical runs
• Connections to punch-down blocks or patch panels
• Applications where cable won't be frequently moved or flexed

When to Choose Stranded:

• Custom patch cord fabrication
• Applications requiring frequent flexing
• Tight-radius bends
• Areas with vibration or movement

Unshielded Construction: The unshielded design makes this cable ideal for:

• Installations where electromagnetic interference is not a concern
• Cost-effective solution for basic alarm circuits
• Residential installations and low-interference commercial environments
• Applications where shielding is not required by specification

22 AWG 4-Conductor Configuration: The 4-conductor design provides:

• Versatility for various security and communication applications
• Sufficient conductors for most CCTV camera installations
• Multiple circuit capability in a single cable
• Color-coded conductors for easy identification and termination

Sequential Footage Marking: The printed footage markers on the jacket allow you to:

• Track cable usage and remaining length
• Calculate exact lengths needed for vertical runs
• Maintain accurate installation documentation
• Avoid waste and ensure adequate supply

Print Legends for Identification: The jacket includes printed legends indicating:

• Cable type and specifications (22/4 CMR CL3R)
• Fire rating (CMR/CL3R)
• Conductor gauge and count
• Compliance certifications

This ensures easy identification during and after installation.

Coil Pack Packaging: The 500 ft coil pack provides:

• Compact storage for job sites
• Easy to transport and handle
• Convenient dispensing during installation
• Protects cable from damage during storage

Installation Best Practices:

• Use solid conductor cable for permanent, fixed installations only
• Do not use solid cable for patch cords or flexible applications
• Maintain minimum bend radius (8x cable diameter for solid conductors)
• Support cable properly per NEC requirements for vertical runs
• Use fire-stopping materials at floor penetrations
• Terminate solid conductors in appropriate connectors or punch-down blocks
• Do not subject solid cable to repeated flexing or movement

Solid Conductor Termination: When terminating solid conductors:

• Use punch-down blocks (110, 66) for professional installations
• Use screw terminals or IDC (Insulation Displacement Connectors)
• Avoid crimping RJ-45 connectors (use stranded for patch cords)
• Ensure proper insertion into terminal blocks

4-Conductor Applications: The 4-conductor configuration is perfect for:

• CCTV cameras requiring power and video
• Basic security alarm zones
• Intercom systems
• Audio distribution (stereo)
• Access control devices
• Any application requiring four wires

This professional-grade solid conductor riser security alarm bulk cable provides reliable, code-compliant performance for permanent vertical installations in residential and commercial buildings where superior electrical performance and cost-effectiveness are required.
