Crestron CRESNET-NP-TL-SP1000 – Cresnet Control Cable, Non-Plenum, 1000 ft Spool

Product Overview

The Crestron CRESNET-NP-TL-SP1000 is a 1000-foot spool of non-plenum rated Cresnet control cable — the certified wiring infrastructure for Crestron Cresnet bus devices including keypads, occupancy sensors, lighting controllers, shade motors, thermostats, and other Cresnet-connected peripherals in commercial AV and building automation installations. Crestron-certified for Cresnet bus performance, it carries both the low-speed RS-485 Cresnet data signal and the 24VDC Cresnet power that devices draw from the control processor, eliminating the need for separate power runs to each Cresnet peripheral device on the bus.

Product Description

Cresnet is Crestron’s proprietary 4-conductor control bus that connects a wide range of room peripherals — keypads, lighting dimmers and switches, occupancy and daylight sensors, motorized shade interfaces, HVAC interfaces, and other low-voltage control devices — to Crestron 4-Series control processors using a single cable run that provides both data communication and 24VDC device power. CRESNET-NP-TL-SP1000 is the standard specification for Cresnet wiring in non-plenum dry-wall and conduit commercial building environments where CMR-rated cable is required by code rather than the CMP plenum rating. The 4-conductor construction provides two data conductors for the RS-485 differential Cresnet signal and two power conductors for 24VDC Cresnet bus power — all four in a single cable, simplifying the low-voltage rough-in and enabling star, daisy-chain, and hybrid bus topologies supported by the Cresnet architecture. At 1000 feet per spool, this is the highest-volume format suited to multi-room commercial installations where large quantities of Cresnet cable are pulled across a building during construction rough-in.

Key Features

• Crestron Certified Cresnet Bus Cable: Factory-certified by Crestron for Cresnet bus performance — ensures reliable RS-485 data communication and 24VDC power delivery to Cresnet peripherals at commercial installation distances without signal degradation or excessive voltage drop.
• Carries Data and Power in One Cable: 4-conductor construction carries both Cresnet RS-485 data and 24VDC bus power in a single cable run, eliminating separate power drops to keypads, sensors, and other Cresnet devices and simplifying low-voltage rough-in in commercial construction.
• Non-Plenum (CMR) Rated: Rated for in-wall and conduit installation in non-plenum commercial building environments — appropriate for standard dry-wall cavity, conduit, and cable tray runs where CMP plenum rating is not required by the local building code.
• 1000-Foot Spool: High-volume spool format minimizes the number of spool changes during large commercial building rough-in, reducing installation labor and waste on multi-room Cresnet deployments.
• Supports Star and Daisy-Chain Topologies: Compatible with Cresnet bus star, daisy-chain, and hybrid wiring topologies supported by Crestron 4-Series control processors and Cresnet hub accessories.
• Compatible with All Cresnet Bus Devices: Works with the full range of Crestron Cresnet keypads, occupancy sensors, lighting controllers, shade motors, thermostats, and other Cresnet-bus peripherals in commercial AV and building automation deployments.

Typical Applications

• Commercial office building Cresnet rough-in for conference room keypads, occupancy sensors, and lighting controllers wired to Crestron 4-Series room control processors
• Higher education campus Cresnet wiring for classroom keypads, lighting dimmers, and shade controllers across multiple rooms
• Corporate campus AV and building automation projects specifying large quantities of Cresnet cable for multi-room deployments during new construction rough-in
• Government facility Cresnet infrastructure for meeting room AV control, lighting, and shade automation
• Hospitality and commercial building Cresnet backbone wiring for room automation systems with large peripheral device counts

Frequently Asked Questions

When do I need plenum-rated Cresnet cable instead of the non-plenum CRESNET-NP?
Plenum-rated cable (CRESNET-P-TL-SP1000) is required when cable runs pass through air-handling plenum spaces — above drop ceilings used as return-air plenums and inside HVAC air ducts — as required by the National Electrical Code (NEC) and local building codes. In non-plenum spaces (conduit, non-plenum wall cavities, cable trays not in plenum), the non-plenum CRESNET-NP is the correct specification. Contact Creation Networks for cable rating guidance for your specific installation environment.

What is the maximum Cresnet bus run length per device?
Cresnet bus maximum run lengths depend on the number of devices on the bus and their combined power draw. Refer to the Crestron Cresnet design guide for maximum distances, or contact Creation Networks for Cresnet bus design and power budget calculations for your installation.

Is a 500-foot spool available?
Yes — the CRESNET-NP-BK-B500 (black, 500 ft) and CRESNET-NP-WH-B500 (white, 500 ft) are available for smaller installations. Contact Creation Networks for spool size selection based on your project cable quantity.

What is the warranty on Crestron Cresnet cable?
