Crestron CRESNET-P-TL-SP1000 – Cresnet Control Cable, Plenum-Rated, 1000 ft

Product Overview

The Crestron CRESNET-P-TL-SP1000 is a 1000-foot spool of plenum-rated (CMP) Cresnet control cable for Cresnet bus wiring in commercial buildings where cable runs pass through air-handling plenum spaces — including above drop ceilings used as return-air plenums and inside HVAC ductwork. Required by the National Electrical Code (NEC) and most local building codes for cable routed in plenum spaces, it provides the same certified Cresnet bus performance as the non-plenum CRESNET-NP cable in a CMP-rated jacket that produces reduced smoke and toxic gas in the event of fire, as required by code for plenum-space wiring.

Product Description

Commercial building construction in North America uses the space above drop ceilings as the return-air plenum in the majority of office, conference, and multi-tenant commercial buildings — and the NEC requires that any cable routed through these plenum spaces use CMP (Communications Multipurpose Plenum) rated cable with a flame-retardant, low-smoke jacket. Specifying non-plenum (CMR) cable in plenum spaces is a code violation that can result in failed inspections and building occupancy issues. The CRESNET-P-TL-SP1000 is the correct specification for Cresnet wiring in these environments: identical Cresnet bus performance to CRESNET-NP, in a CMP-rated jacket that satisfies NEC plenum requirements. In many commercial building projects, the majority of Cresnet cable runs pass through plenum ceiling spaces as they route from the AV closet or electrical room to keypads, sensors, and lighting controllers at each room, making plenum-rated cable the standard specification for most commercial Cresnet rough-in rather than an exception. AV specifiers and electrical contractors should confirm ceiling construction type with the general contractor or architect before specifying cable rating for each Cresnet run.

Key Features

• Plenum-Rated (CMP) Jacket: CMP fire rating meets NEC and local building code requirements for cable routed through air-handling plenum spaces in commercial buildings — required for above-drop-ceiling runs in plenum-ceiling commercial construction.
• Crestron Certified Cresnet Performance: Factory-certified for Cresnet bus RS-485 data communication and 24VDC power delivery — same electrical performance as CRESNET-NP in a plenum-rated jacket.
• Data and Power in One Cable: 4-conductor construction carries both Cresnet RS-485 data and 24VDC bus power to all Cresnet peripheral devices, eliminating separate power drops in plenum-routed commercial AV wiring.
• 1000-Foot Spool: High-volume spool format for large commercial building Cresnet rough-in across multiple floors and rooms where plenum ceiling routing is the primary installation path.
• Compatible with All Cresnet Devices: Works with the full range of Crestron Cresnet keypads, sensors, lighting controllers, shade motors, and other Cresnet-bus peripherals — same termination and bus topology as non-plenum cable.
• Code-Compliant Specification: Ensures NEC plenum-space compliance on commercial AV installations subject to inspection — required for projects where the electrical inspector will verify cable rating in plenum-ceiling spaces.

Typical Applications

• Commercial office building Cresnet rough-in where drop ceiling plenum routing is used for runs from AV closets and electrical rooms to conference room keypads, occupancy sensors, and lighting controllers
• Multi-tenant commercial buildings where plenum ceiling cable runs are required by code and building management
• Higher education and government facility Cresnet wiring in plenum-ceiling construction
• Hospitality properties and commercial buildings with drop-ceiling plenum construction requiring NEC-compliant Cresnet infrastructure cable

Frequently Asked Questions

How do I know if my installation requires plenum or non-plenum Cresnet cable?
If any Cresnet cable run passes through the space above a drop ceiling that is used as a return-air plenum, plenum-rated (CMP) cable is required by the NEC. Confirm ceiling construction type (plenum vs. non-plenum) with the general contractor, building architect, or mechanical engineer for the specific project. Contact Creation Networks for cable specification guidance.

Can plenum cable be used in non-plenum spaces?
Yes — CMP plenum cable can be used in both plenum and non-plenum spaces. It is always acceptable to upgrade from non-plenum to plenum rating. Non-plenum cable (CMR) cannot be used in plenum spaces. For projects with mixed plenum and non-plenum runs, specifying plenum cable throughout simplifies procurement and eliminates the risk of using non-plenum cable in a plenum-rated section by mistake.

Is a 500-foot plenum spool available?
Contact Creation Networks for plenum Cresnet cable availability in smaller spool sizes for installations where 1000 feet exceeds the project cable requirement.
