Crestron ZUMMESH-JBOX-PSU Zūm J-Box Accessory Power Supply

It is the Zūm J-Box Accessory Power Supply. It mounts to a 4 in. square junction box and provides a host for a Zūm Network Bridge (ZUMMESH-NETBRIDGE) or Zūm Contact Closure Output (ZUMMESH-CCO), communicating wirelessly with other Zūm Mesh devices in a Zūm commercial room lighting system.

No. Crestron describes it as similar to a ZUMMESH-JBOX load controller but without any dimming or switch circuitry onboard. Its job is to power and host a Zūm Network Bridge or Zūm Contact Closure Output, and to communicate with other Zūm Mesh devices in the room.

It hosts either the ZUMMESH-NETBRIDGE Zūm Network Bridge or the ZUMMESH-CCO Zūm Contact Closure Output. The Contact Closure Output adds a low-voltage SPDT form C relay controlled by room occupancy for HVAC integration, and takes its power and wireless communication from the J-Box device it snaps onto.

It is line powered from 100-277VAC and connects through flying leads. It knockout mounts to a standard 4 in. square junction box, is UL 2043 listed for installation in an environmental air handling space, and meets the UL 916 standard for energy management equipment.

It uses Zūm Mesh peer-to-peer RF and pairs with Zūm dimmers, switches, occupancy sensors, vacancy sensors and daylight sensors. It communicates wirelessly with those devices to enable centralised monitoring and management. Crestron's Zūm Lighting Control System Setup Guide (Doc # 7957) covers setup.
