Product Overview

The Crestron Zūm® Wired ZUMNET‑JBOX‑16A‑LV provides 0‑10V dimming for drivers and ballasts. The device can be wired to Zūm Net devices for network expansion and to Zūm Link devices for in‑room control. Energy-saving options are available to enable daylighting, occupancy or vacancy sensing, and centralized monitoring and management.

Zūm Net Wired Technology
In a Zūm network, ZUMNET‑JBOX devices facilitate communications between rooms via ethernet and can be daisy‑chained for network expansion. Each device in the chain communicates to a control system for centralized monitoring, management, and reporting. Zūm Link devices connect to ZUMNET-JBOX devices to provide in‑room lighting control. Similar to the Zūm Wireless system, Zūm Link devices work together in a local ecosystem to provide customized solutions as needed.

Energy Management and Efficiency
ZUMNET-JBOX devices are capable of energy monitoring via the Crestron XiO Cloud™ service or through custom programming. Occupancy sensor, vacancy sensor, and daylight sensor connectivity allow for significant energy savings. To reduce energy usage, lights will turn off automatically when the room is vacant and dim gradually according to the amount of natural daylight in the room.

Easy Installation
For flexibility and ease‑of‑use, Zūm load controllers are installed in a room with Zūm keypads, occupancy or vacancy sensors, and/or a daylight sensor for complete commercial lighting control. Finish the installation by quickly commissioning the room through the Zūm app.

Override Contact Closure Input
An integrated contact closure input or relay output on the ZUMNET‑JBOX‑16A‑LV provides the means to place all connected Zūm Net and Zūm Link devices into Emergency Override mode.
