Honeywell 32151012 Cable

Experienced contractors know that signal integrity in high-interference environments starts with the right 18/4 shielded plenum cable. The Honeywell 32151012 is engineered specifically for clean data transmission in commercial air-handling spaces. Featuring four 18 AWG stranded bare copper conductors, this 1000-foot reel provides the flexibility required for tight pulls through conduit or open plenum ceilings. The overall aluminum foil/mylar shield, combined with a 24 AWG tinned copper drain wire, effectively mitigates EMI and RFI, making it the standard choice for building automation systems, security interfaces, and complex HVACR control circuits.

This CMP/CL2P/FT6 rated cable meets strict NFPA 262 flame safety standards, ensuring compliance for installation in plenum voids without the need for additional conduit. The low-smoke PVC jacket features sequential footage markings to eliminate guesswork during long runs, while the 300V rating and 19-strand construction offer a superior balance of electrical capacity and physical durability. Whether you are wiring intercom systems, thermostat controls, or low-voltage security circuits, this Honeywell Genesis series cable delivers professional-grade reliability where signal clarity is non-negotiable.

• EMI/RFI Protection: The overall foil shield ensures reliable performance for sensitive 18/4 control cable applications.
• Code Compliant: CMP/CL2P/FT6 listing allows for legal installation in air-handling plenums.
• Efficient Install: Stranded copper conductors and a built-in rip cord facilitate faster terminations and stripping.
• Accurate Tracking: Sequential footage markings on the jacket help technicians manage inventory and cable drops.
• Robust Construction: Rated for temperatures between -20°C and 75°C to handle standard mechanical room environments.

Is 18/4 shielded cable required for standard thermostat wiring?
While standard unshielded wire works for many basic setups, shielded plenum wire like the 32151012 is necessary when cables run near high-voltage lines or in environments with high electrical noise to prevent signal "ghosting" or equipment errors.

What is the difference between CMP and CMR ratings?
CMP (Plenum) is a higher fire-safety rating than CMR (Riser). CMP cable, such as this Honeywell 32151012, can be used in both plenums and vertical risers, whereas CMR cannot be used in air-handling spaces.

How should the shield drain wire be terminated?
For the best interference rejection, most HVACR technical specifications recommend grounding the tinned copper drain wire at the controller end only to avoid creating ground loops.
