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

Common Use Cases

• Commercial Office Buildings: Single-zone security in plenum spaces near computers and office equipment
• Retail Stores: Point-of-sale security with EMI protection from electronic equipment
• Data Centers: Security sensors near high-EMI server and networking equipment
• Healthcare Facilities: Medical facility security near diagnostic and treatment equipment
• Educational Institutions: Classroom or office security in plenum ceiling environments
• Industrial Facilities: Security systems in light manufacturing with electrical interference
• Financial Institutions: Secure areas requiring both fire safety and EMI protection
• Government Buildings: Critical spaces with strict fire and interference requirements
• Professional Offices: Attorney, accounting, or medical offices with security needs
• Smart Buildings: Basic security integration in intelligent building systems

Print Legend Benefits

Time-Saving Identification: The cable jacket includes printed information such as:

• Wire gauge and conductor count (22 AWG 2C)
• Shielding type (SHIELDED)
• Fire rating (TYPE CL3P/FPLP, TYPE CMP)
• Certification marks (c(ETL)us)
• Sequential footage marking

Installation Advantages:

• Quick Verification: Instantly confirm correct cable during installation
• Code Compliance: Inspectors can easily verify proper cable type
• Future Service: Technicians can identify cable specifications without testing
• Documentation: Simplifies creating as-built drawings and documentation
• Error Prevention: Reduces chances of installing wrong cable type

EMI Protection Explained

Common Sources of Electromagnetic Interference:

• Fluorescent lighting and ballasts
• Electric motors and HVAC equipment
• Computer and networking equipment
• Radio frequency (RF) transmitters
• Power transformers and inverters
• Variable frequency drives (VFDs)
• Elevators and escalators

How EMI Affects Unshielded Security Cables:

• False alarms from sensor circuits
• Intermittent signal degradation
• Unreliable device communication
• System malfunctions and nuisance trips
• Increased service calls and maintenance costs

Shielding Solution: Aluminum foil shielding intercepts these electromagnetic waves, preventing them from inducing currents in the signal conductors. Proper grounding allows the shield to safely divert interference to ground.

When to Choose This Cable

Perfect For:

• Single-zone security installations in plenum spaces with EMI concerns
• Upgrading existing systems experiencing interference-related false alarms
• Commercial buildings requiring both fire safety and EMI protection
• New construction with plenum space requirements and electrical noise
• Professional installations where reliability is critical
• Code-required plenum installations in EMI-sensitive environments

Consider Alternatives If:

• Multiple zones needed (consider 22/4 or 22/6 shielded plenum)
• Minimal EMI concerns (22/2 unshielded plenum may suffice)
• Very long runs required (consider 18/2 shielded plenum for heavy-duty)
• Non-plenum spaces (CMR riser shielded may be more cost-effective)
• Extreme EMI environment (consider double-shielded or twisted pair options)

Building Code Compliance

Before Installation, Verify:

• Local fire marshal requirements for plenum spaces
• Building code specifications for fire-rated cable
• NEC article compliance for specific application
• Manufacturer requirements for security/fire alarm panels
• Jurisdictional requirements for shielded cable

This cable meets or exceeds:

• National Electrical Code (NEC) Articles 760, 800, 725
• CMP plenum requirements for air-handling spaces
