16/2 Metal Clad Fire Alarm 600V Coil
Product overview: This 16/2 MC cable uses red interlocked armor for easy identification and system separation, with aluminum armor that is significantly lighter than steel. It is designed to reduce installation costs by up to half compared with traditional pipe-and-wire methods. The armor provides robust protection for fire alarm conductors in commercial spaces, and the 600-volt rating supports typical signaling and power needs for detectors and control equipment. Its lightweight construction can simplify routing through ceilings, walls, and equipment rooms while maintaining mechanical protection.
Syston 18/2 Fire Alarm Wire 100 ft
Product overview: This 18/2 fire alarm cable features solid copper conductors and a plenum-rated FPLP/CL3P/FT6/CMP construction, enabling use in air handling spaces. The cable is UL and ETL listed for indoor and outdoor use, with UV resistance and RoHS compliance. Its plenum-rated jacket is essential for spaces that circulate air, helping to reduce fire and smoke propagation risks while maintaining signal integrity for devices like detectors, pull stations, and addressable modules.
16/2 Metal Clad Fire Alarm 600V 1000 ft Reel
Product overview: This long-length MC cable provides the same protective aluminum armor as other MC options, suitable for major installations like campuses or large commercial facilities. The 1000-foot reel reduces reel changes and handling on large jobs. It maintains the 600-volt rating and two-conductor plus ground configuration, suitable for power feeds to alarm panels, local power supplies, and central signaling devices.
EWCS 18 AWG 2/C Shielded FPLR 1000 ft
Product overview: This 18 AWG two-conductor shielded fire alarm cable is FPLR/riser rated and UL-listed for vertical and between-floors installations. It features a red PVC jacket and a Mylar/aluminum shield to minimize EMI, helping ensure EMI-free signaling for detectors, pull stations, and sirens. The 1000-foot reel is ideal for mid-sized projects, providing ample length to reduce splices and simplify routing.
Syston 18/4 Fire Alarm Wire 250 ft Shielded
Product overview: This Syston cable provides four conductors with solid copper conductors and shielded construction to mitigate EMI. It is listed for fire alarm and signaling circuits with FPLR/CL3R/FT4/CMR riser-rated capabilities, making it suitable for multi-point sensor networks, control circuits, and emergency signaling across floors. The shielded design supports more reliable data transmission in environments with significant electrical noise from equipment or communication systems.
EWCS 18 AWG 2/C Shielded FPLR 1000 ft
Product overview: This 18 AWG shielded fire alarm cable uses a dual-conductor design with shield to protect against EMI and interference in signaling circuits. It is UL-listed for FPLR/Riser use and includes a red jacket, ensuring easy identification and compatibility with NEC requirements for between-floor installations. The shield helps maintain signal integrity for detectors, annunciators, and control devices in demanding environments.
Buying Guide for Fire Alarm MC Cable
Key considerations influence long-term performance and code compliance when selecting MC cable for fire alarm and life-safety systems. The following perspectives help buyers compare options objectively:
- Conductor configuration: Determine the required number of conductors and ground conductors for your system. Two-conductor cables support basic signaling and power, while four-conductor and shielded variants accommodate more complex networks and EMI-prone areas.
- Armor and protection: Aluminum armor offers lighter weight and easier handling than steel, which can reduce labor time. For high-abrasion or exterior routes, armor protection helps guard against physical damage.
- Plenum and riser ratings: FPLP/CL3P/FT6/CMP plenum-rated cables are designed for air-handling spaces, reducing fire and smoke hazards. Riser-rated cables are suitable for between-floor installations. Avoid outdoor-only use unless explicitly rated for it.
- Shielding: Shielded cables (Mylar/aluminum or other shielding) minimize EMI, improving reliability in electrically noisy environments with equipment like HVAC systems, motors, or radio devices.
- UL/ETL listings: Verify that the product carries appropriate safety certifications and is listed for fire alarm and signaling use in your jurisdiction. This ensures compliance with NFPA 72 and NEC codes.
- Length and spooling: Large projects benefit from longer reels to minimize splice points and installation interruptions. Confirm spool length fits project scope and storage constraints.
- Jacket color and labeling: Red jackets or armor assist quick identification during maintenance and inspections. Clear labeling helps reduce confusion at multi-line installations.
- Cost vs. labor: While MC cables with plenum ratings and shielding may have higher upfront costs, they can reduce installation time and future maintenance, improving total cost of ownership.
When choosing the right option, balance protection, signaling performance, ease of handling, and code compliance. For most fire alarm projects, select plenum-rated or riser-rated shielded cables with solid copper conductors and a suitable conductor count for the system’s devices and panels. Always consult local electrical codes and fire safety standards to confirm specific requirements for your building type and occupancy.
