EWCS 18 AWG 2/C FPLP Plenum Rated Fire Alarm Cable
These UL approved plenum/FPLP cables are designed for fire alarm and signal control circuits, with NEC-recognized ratings for plenum spaces. The two solid copper conductors (Black and Red) are insulated with Low Smoke PVC, and a choice of jacket colors supports circuit identification. Rated for 300 volts at 75°C, the cable’s diameter is approximately 0.143 inches and ships on a 12-inch plywood spool. Footage markings aid inventory management in large runs, and the 20-pound-per-1000-feet weight keeps handling practical for long installs.
EWCS 18 AWG 2/C FPLR Riser Shielded Fire Alarm Cable
This UL-certified FPLR cable is ideal for between-floor runs and non-plenum spaces, offering a shielded design with an aluminum Mylar shield and a 24 AWG tinned copper drain wire. The red jacket identifies circuit type and ensures robust EMI protection while maintaining a 300-volt, 75°C rating. Weight is about 21 pounds per 1000 feet, with a 0.155-inch diameter, and it includes a rip cord for easy stripping. Spool comes on a 12-inch plywood core for convenient deployment in large installations.
SYSTON 18/6 Fire Security Burglar Station Cable
Designed for a broad range of low-voltage applications, this 18/6 cable uses 100% copper conductors with a shield to minimize EMI and preserve signal integrity. It is suitable for fire alarm, security, PA systems, and related control circuits. The aluminum foil shield enhances resistance to interference, contributing to reliable performance in environments with multiple electrical devices and high data transmission demands.
SYSTON 18/2 Fire Security Burglar Station Cable
This 18/2 shielded, plenum-rated cable uses UL/ETL listed copper conductors to support fire alarm and burglar alarm signaling. CMP/CL3P (Plenum-Rated) construction ensures safety in air-handling spaces, and UV resistance extends the cable’s usable life in indoor/outdoor applications. The shielding protects critical signals from EMI, making it suitable for high-sensitivity alarm and notification systems within complex building layouts.
EWCS 16 AWG 2/C FPLP Plenum Rated Shielded Cable
With 16 AWG two-conductor copper build, this shielded FPLP cable is rated for plenum spaces and is suitable for fire alarm circuitry and signal control. The shield employs an aluminum Mylar layer, plus a 24 AWG tinned copper drain wire, delivering both EMI protection and dependable grounding. The red jacket provides quick visual identification, and a 300-volt, 75°C rating supports robust performance across typical building environments. Spool packaging matches the needs of longer installations.
SYSTON 18/3 Fire Security Burglar Station Cable
This 18/3 configuration is designed for versatile low-voltage signaling, fire alarm signaling, and security systems. It is CMP/CL3P plenum-rated and UL/ETL listed, with UV resistance suitable for indoor/outdoor use. The copper conductors provide reliable signal transmission, while the shielding option helps maintain signal integrity in spaces with high electromagnetic interference. The product supports broad compatibility with modern alarm and notification networks.
SYSTON 18/2 Plenum-Rated Shielded Cable
This 18/2 plenum-rated shielded cable emphasizes reliable signal transmission in fire alarm and security systems, leveraging 100% copper conductors and an aluminum foil shield to mitigate EMI. CMP/CL3P rating positions it for plenum spaces, and UV resistance supports long-term indoor/outdoor use. The product’s robust shielding and conductor quality make it suitable for complex building installations with multiple signaling paths.
Buying Guide: Plenum-Rated Fire Alarm Cable Purchase Considerations
- Plenum rating and code compliance: Ensure the cable is CMP/CL3P or FPLP/FPLR to meet NEC requirements for air-handling spaces and building codes.
- Conductor material and construction: Look for 100% copper conductors, either solid or stranded, depending on fill and bend requirements. Shielded varieties help combat EMI in dense electrical environments.
- Jacket material and color: Low Smoke PVC jackets improve safety and identification. Red jackets often denote fire alarm signaling circuits, while other colors aid circuit differentiation.
- Voltage and temperature rating: Check for a minimum of 300V and 75°C ratings to suit typical building installation conditions.
- Shielding: Aluminum Mylar shields reduce EMI and preserve signal integrity; drain wires improve grounding and stripping ease.
- Installation considerations: Plenum-rated cables are bulkier; verify reel/spool dimensions, weight per 1000 ft, and ease of stripping with rip cords for efficient installations.
- Size and pair count: Choose AWG and pair counts based on required signaling paths, distance, and future expandability, balancing flexibility with cost.
- Environmental suitability: UV resistance, outdoor applicability, and exposure to moisture can influence cable selection in campus and exterior wall runs.
- Compliance and testing: Verify UL/ETL listings, and confirm compatibility with your fire alarm panel, detectors, and notification devices.
When selecting plenum-rated fire alarm cable, balance protection and performance with ease of installation. Shielded options support critical data paths in complex facilities, while unshielded variants offer cost-effective solutions for straightforward layouts. Always confirm local code requirements and consult with a licensed electrician or fire-safety professional to finalize the best choice for your project.
