Why Choose Shielded 22/4 Plenum Cable?
✓ EMI/RFI Protection - Aluminum foil shielding prevents interference from electrical equipment and radio frequencies
✓ Multi-Zone Capability - Four conductors support two independent circuits or multiple security zones
✓ Fire Code Compliant - CMP/FT6 rating meets stringent requirements for air-handling spaces
✓ Low Smoke Safety - Special insulation reduces toxic emissions during fire emergencies
✓ Versatile Integration - Single cable handles security, intercom, and control applications
✓ Professional Reliability - Shielding eliminates false alarms from electromagnetic interference
✓ Cost-Effective Installation - Consolidates multiple systems into one cable run
Plenum Installation Requirements
Use CMP Plenum Cable When:
- Installing in HVAC plenums or air-return spaces
- Running cable above drop ceilings used for air circulation
- Building codes require low-smoke, fire-resistant materials
- Commercial installations with strict fire safety codes
- Installing in any space used for environmental air
Critical: Plenum cable exceeds all riser (CMR) specifications and can substitute for riser cable anywhere, but riser cable cannot be used in plenum spaces. Always verify local building codes and fire marshal requirements.
Common Use Cases
- Commercial Office Buildings: Multi-zone security systems in plenum ceiling environments
- Retail Stores: Point-of-sale security with EMI protection from electronic equipment
- Data Centers: Server room security near high-EMI networking equipment
- Healthcare Facilities: Medical facility security near diagnostic equipment
- Educational Institutions: Multi-zone campus security with integrated intercom
- Industrial Facilities: Security systems in manufacturing environments with machinery
- Financial Institutions: ATM and vault security requiring shielded protection
- Government Buildings: Critical infrastructure with strict fire and EMI requirements
- Multi-Tenant Buildings: Separate security zones for different tenants or floors
- Smart Buildings: Integration of security, access control, and building automation
EMI Protection Explained
Electromagnetic interference (EMI) in security systems can cause:
- False alarms from sensor circuits
- Intermittent communication failures
- Unreliable device operation
- System malfunctions and service calls
How Aluminum Foil Shielding Works: The aluminum foil acts as a barrier, intercepting electromagnetic waves before they reach the signal conductors. When properly grounded at one end, the shield diverts interference to ground, protecting signal integrity and preventing false alarms.
FT6 Fire Rating Explained
FT6 Rating is the Canadian equivalent of the CMP plenum rating:
- Same fire safety performance as CMP
- Recognized in Canadian building codes
- Fully interchangeable with CMP-rated cable
- Low flame spread and smoke generation
- Suitable for plenum spaces in both US and Canadian installations
When to Choose This Cable
Perfect For:
- Multi-zone security installations in plenum spaces
- Commercial buildings requiring fire-rated, shielded cable
- Integrated security and intercom systems
- Environments with moderate to high electrical interference
- Code-required plenum installations needing EMI protection
- Professional installations requiring maximum reliability
Consider Alternatives If:
- Single zone applications (22/2 may be more cost-effective)
- Non-plenum spaces where riser (CMR) rating is acceptable
- Very high interference environments (consider 18 AWG for longer runs)
- Minimal EMI concerns (unshielded may suffice)
- More than 4 conductors needed (consider 22/6 or 18/8)
Value Proposition
This 22/4 shielded plenum cable represents the ideal balance of:
- Performance: EMI protection + multi-zone capability
- Safety: CMP/FT6 plenum rating for fire code compliance
- Cost: More economical than higher-gauge shielded alternatives
- Versatility: Suitable for security, intercom, and control applications
- Quality: USA-made with ETL certification and RoHS compliance
For professional installers seeking reliable, code-compliant cable with EMI protection at a competitive price point, this 22/4 shielded plenum cable delivers exceptional value.
