Cresnet is Crestron’s proprietary 4-conductor control network cable that connects Cresnet-compatible keypads, sensors, thermostats, and modules to a Crestron control processor. The plenum rating qualifies this cable for installation in air-handling ceilings and HVAC plenums per applicable fire and building codes.\u003c\/p\u003e\u003ch2\u003eProduct Description\u003c\/h2\u003e\u003cp\u003eCresnet cable provides the wired communication and power distribution backbone for Crestron control systems. The four conductors carry +24VDC power, ground, and the two-wire Cresnet data bus that links up to 253 addressable devices per network. Plenum-rated cable (CMP-rated) is required by the NEC and local building codes when cable is routed through air-handling spaces—including suspended ceiling plenums, raised access floors used for HVAC return air, and dedicated air-handling shafts. The CRESNET-P-BK-SP500 provides 500 feet of cable on a spool convenient for pull-through installation in commercial projects. The black jacket matches standard black cable infrastructure and is appropriate for installations where jacket color is specified for system identification. Sold by the spool; specify additional spools for larger projects or purchase CRESNET-P-BK-SP1000 for 1000-foot runs.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePlenum-rated (CMP) Cresnet control cable for air-handling space installations\u003c\/li\u003e\n\u003cli\u003eBlack jacket for system identification and infrastructure color coding\u003c\/li\u003e\n\u003cli\u003e500-foot (152 m) spool for commercial pull-through installation\u003c\/li\u003e\n\u003cli\u003e4-conductor: +24VDC power, ground, and 2-wire Cresnet data bus\u003c\/li\u003e\n\u003cli\u003eSupports up to 253 Cresnet-addressable devices per network\u003c\/li\u003e\n\u003cli\u003eCompatible with all Cresnet-enabled Crestron keypads, sensors, and modules\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTypical Applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCommercial AV integration requiring plenum-rated cable in suspended ceiling spaces\u003c\/li\u003e\n\u003cli\u003eOffice building automation wiring in air-handling ceiling plenums\u003c\/li\u003e\n\u003cli\u003eHealthcare, education, and institutional projects with strict plenum cable requirements\u003c\/li\u003e\n\u003cli\u003eAny installation where NEC or local code mandates CMP-rated wiring in plenums\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e CRESNET-P-BK-SP500\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCable Type:\u003c\/strong\u003e Cresnet, 4-conductor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRating:\u003c\/strong\u003e Plenum (CMP)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eJacket Color:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 500 ft (152 m) spool\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConductors:\u003c\/strong\u003e 4 (+24VDC, GND, NET+, NET-)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eQ: When is plenum-rated Cresnet cable required?\u003c\/strong\u003e\u003cbr\u003eA: Plenum-rated cable is required by the NEC and local building codes whenever cable is installed in air-handling spaces, including suspended ceiling return-air plenums. Non-plenum (NP) cable may not be used in those spaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ: What is the difference between CRESNET-P-BK-SP500 and CRESNET-NP-WH-SP1000?\u003c\/strong\u003e\u003cbr\u003eA: CRESNET-P-BK-SP500 is plenum-rated and black, in a 500-ft spool. CRESNET-NP-WH-SP1000 is non-plenum (riser-rated), white, on a 1000-ft spool. Use plenum-rated cable in air-handling spaces and non-plenum in riser\/conduit runs.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ: Can CRESNET-P-BK-SP500 be used on the same Cresnet network as non-plenum Cresnet cable?\u003c\/strong\u003e\u003cbr\u003eA: Yes. Cresnet cable type (plenum vs. non-plenum) is a physical installation rating, not a system compatibility issue. Both cable types carry the same Cresnet signals and can be part of the same network homerun.\u003c\/p\u003e","brand":"Crestron","offers":[{"title":"Default Title","offer_id":47759580528876,"sku":"CRESNET-P-BK-SP500","price":550.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0603\/7982\/4364\/files\/master_photo_a-cresnet-p.png?v=1781795078","url":"https:\/\/creationnetworks.net\/products\/crestron-cresnet-p-bk-sp500","provider":"Creation Networks","version":"1.0","type":"link"}
