Key Features

  •  Zūm® wired junctionbox mounted multi-purpose integration and timeclock device
  •  Powered by Zūm linkbus
  •  Provides a standaloneastronomical time clock and local time and date settings without a ZUM‑HUB4 orcontrol system
  •  Provides adistributed, room level interface to third-party smart controllers, such asHVAC/VAV systems and shade controllers
  •  Supports in‑roomdevice daisy chaining with other Zūm wired devices
  • Cover mount to a standard 4 in. square junction box

Product Overview

The ZUMLINK‑JBOX‑IO is a compact, multi-purpose, standalone integration and timeclock device that applies schedules, events, and common integration protocols to a Zūm space without the need for a control system. As a Zūm Wired device, the ZUMLINK‑JBOX‑IO can be discovered by the Zūm app for easy configuration without custom programming. If needed, the ZUMLINK‑JBOX‑IO can also connect to a Crestron control system. The ZUMLINK‑JBOX‑IO mounts to a standard 4 in. square junction box, provides two Zūm Link serial bus RJ-45 ports, an RS-232 port, an RS-485 port, two dry contact closure outputs, two low-voltage inputs, and two low-voltage inputs with LED indicator light support. The ZUMLINK‑JBOX‑IO supports in‑room device daisy chaining to any 24VDC Zūm Link run.

Zūm Link Wired Technology

Zūm Link technology enables in‑room  lighting control through keypads and sensors wired to controllers. Zūm Wired  devices connect via CBL-CAT5E-ZUMLINK-P CAT5e cable (sold separately) to RJ‑45  ports to provide simple daisy-chaining and lighting control of compatible  loads. The Zūm Wired devices work together in a local ecosystem to provide  customized solutions using the Zūm app.


Easy Installation

The ZUMLINK‑JBOX‑IO installs in a  standard four-inch square junction box. Depending on the installation  requirements of the space, the ZUMLINK‑JBOX‑IO can be installed with the  connections facing out or into the junction box. Connect the ZUMLINK‑JBOX‑IO  to Zūm devices (load controllers, keypads, and sensors) utilizing Zūm Link  connections.


Astronomical Time-Clock Control

Enables control of standalone Zūm spaces  based on date and time without the need for system networking or a centralized  control hub. Configure date and time, schedules, events, and holidays from  the Zūm app directly to the space.

Controls and Indicators


(2) Pushbutton and (1) green LED;
 Indicates On/Off status of connected load;
 Lights briefly to indicate a button press


(2) Bi-color LED;
 Power indicator;
 Turns red when power is first applied for  approximately 0.5 seconds and then turns green


(2) Green LED;
 LED lights green in normal operation


(2) Green LED indicates when:
 A unit is part of a Zūm Link network;
 The time and location have been set;
 One or more timeclock events have been configured;

The LED blinks for 0.5 seconds  on/off when timeclock is in manual or maintained override



(2) 3-pin terminal  blocks for output relays;
 30VAC/VDC 1A;
 Each terminal accepts one 20-24 AWG wire

(2) 2-pin terminal  blocks for input relays without keyswitch support
 Each terminal accepts one 20-24 AWG wire


(1) 5-pin terminals block
 Each terminal accepts one 20-24 AWG wire

NOTE: The    RS‑232 COM port is intended for use with relatively simple devices that    send and receive small packets and do not generate a lot of data. A small    amount of delay may be normal when sending or receiving some control    commands on a low-speed serial network. Zūm and Cresnet networks with many    devices tend to exhibit more delay.
