Why Choose Plenum 22/4 Cable?

✓ Fire Code Compliant - CMP rating required for air-handling spaces above drop ceilings
✓ Low Smoke Design - Special insulation reduces toxic emissions during fire emergencies
✓ Multi-Zone Capability - Four conductors support multiple security zones or devices
✓ Versatile Performance - Single cable handles security, intercom, and audio applications
✓ Dual Certification - Both UL and ETL listed for comprehensive safety assurance
✓ Professional Quality - USA manufacturing ensures consistent, reliable performance

Plenum vs. Riser: When to Use CMP

Choose Plenum (CMP) Cable When:

• Installing in HVAC plenums or air-handling spaces
• Running cable above drop ceilings used for air circulation
• Building codes require low-smoke, fire-resistant materials
• Commercial installations with strict fire safety requirements

Note: Plenum cable exceeds riser (CMR) specifications and can be used anywhere riser cable is acceptable, but the reverse is not true. Always verify local building codes and requirements.

Installation Advantages

The 22/4 plenum configuration provides excellent versatility for integrated security systems. The white low-smoke jacket meets stringent fire safety codes while providing a clean appearance. Sequential footage marking ensures precise measurements, reducing waste and installation time. The 7-strand construction offers superior flexibility for tight bends and routing through conduits.

Common Use Cases

• Commercial Buildings: Security systems in offices with plenum air-return ceilings
• Multi-Zone Security: Connect door contacts, motion sensors, and glass break detectors
• Integrated Systems: Combine security and intercom on separate conductor pairs
• Audio Distribution: Background music or paging systems in commercial spaces
• Access Control: Card readers, electric strikes, and magnetic locks
• Building Automation: HVAC controls, lighting controls, and environmental sensors
