The Crestron Zūm® Wired ZUMLINK‑JBOX‑20A‑SW provides zero cross switching for high inrush lighting control. The device can be wired to other in‑room Zūm devices to provide load control. Energy-saving options are available to enable daylighting, occupancy or vacancy sensing, and centralized monitoring and management.
Zūm Link Wired Technology
Zūm Link technology allows for in‑room lighting control through compatible keypads and sensors. Two RJ‑45 ports on the device allow for connection to a Zūm Net device and for in‑room device daisy‑chaining. Similar to the Zūm Wireless system, Zūm Link devices work together in a local ecosystem to provide customized solutions as needed.
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 ZUMLINK‑JBOX‑20A‑SW provides the means to place all connected Zūm Net and Zūm Link devices into Emergency Override mode.
