SYSTON 18/2 Fire Security Cable – Shielded Plenum-CMP/CL3P, 100% Copper, UL/ETL, UV Resistant

Overview

Meet the SYSTON 18/2 Fire Security Burglar Station Sound Alarm Control Cable, a purpose-built low-voltage solution designed to carry critical signals with clarity. Built for demanding indoor and outdoor environments, this shielded, plenum-rated cable balances reliability with safety, helping you power and connect essential security and communication systems without compromise.

Why this cable stands out

• Pure copper conductors deliver strong, consistent conductivity for dependable system performance.
• Aluminum foil shielding minimizes electromagnetic interference (EMI), preserving signal integrity even in busy electrical spaces.
• CMP/CL3P plenum-rated jacket meets strict safety standards for air-handling spaces, reducing flame spread risk in ceilings and ducts.
• 300V CL3 rating provides a comfortable insulation margin for thermostats, alarms, and low-voltage devices.
• UL and ETL listings indicate compliance and tested performance for both indoor and outdoor installations.

Real-world use scenarios

In schools, office buildings, hospitals, or multi-dwelling facilities, this cable can link fire alarms, burglar alarms, public address systems, intercoms, telephone stations, and nurse call networks. The shielded design helps protect data and control signals over longer runs or in environments with electrical noise, while the UV-resistant jacket adds resilience for exterior or semi-exposed deployments.

Key benefits at a glance

• Reliable low-voltage signaling with high-purity copper cores
• Clear communications enabled by effective EMI shielding
• Plenum-rated construction designed for safe installation in airspaces
• Flexible, 300V-rated CL3 circuit suitability for a range of devices
• Certified performance through UL/ETL listings for added confidence

Installation guidance and compatibility

Choose this shielded, plenum-rated wire for runs across ceilings, air ducts, and other indoor spaces where safety and signal quality matter. Maintain proper bend radii for stranded conductors and follow local codes for low-voltage wiring. Verify that system components and panels align with the CL3P and CMP ratings to ensure optimal operation.

Note: This cable is designed for power-limited applications within approved environments. The combination of copper conductors, shielding, and robust rating helps support reliable performance without making guarantees about specific outcomes.
