Solution For The Wireless Control Of Lighting, HVAC, And Plug Load

xCella™ Wireless from Acuity Controls allows for the wireless control of lighting, HVAC, and plug load in small spaces such as classrooms, offices, and gymnasiums. Installed in a variety of retrofit and new construction applications, it deploys quickly for simple room control that can also be networked for a floor or building-wide solution.

wireless controlxCella Wireless features battery-free switches, sensors, and load controls that are operational in seconds. The wireless control systems are easily configured in the field using Pair & Play™ technology, or can be delivered on-site pre-packaged by room to reduce costs, errors, and time of deployment.

The xCella Wireless control system is composed of remote modules, wireless switches, wireless sensors, and additional controls. It can operate as a full standalone wireless control solution or combine with other Acuity Controls products to create a hybrid wired/wireless solution complete with switching and dimming relay panels, BMS integration, and Unity GX2 floor plan control, monitoring, and analytics software.

The xCella Wireless Photosensor (PCELL WRI) communicates to xCella Remote Modules or Wireless Receivers using RDT wireless technology to raise or lower light levels based on available natural light. It is powered by built-in photovoltaic cells and is designed to be ceiling mounted where one of the photovoltaic collectors is facing a window or source of light. The photovoltaic cell must receive at least 20 foot-candles of light for several hours a day to charge the storage capacitor. Optional coin batteries can be used if low light levels are encountered. The xCella Wireless Photosensor uses an STM 110C EnOcean Transmitter to transmit data every 10 seconds if light level change is detected. It can transmit a signal to a receiver up to 90′ away and a Wireless Receiver (GR2400 WREC) must be on the GR 2400 Bus within the transmitting distance.

xCella Wireless Occupancy Sensors communicate to xCella Remote Modules or Wireless Receivers using RDT wireless technology to automatically turn off lighting when the space is not in use. They transmit data every 10 seconds if light level change is detected with a 90′ maximum indoor range and are available in ceiling mounted and wall mounted forms. Wireless Occupancy Sensors are powered by built-in photovoltaic cells and use passive infrared (PIR) motion detectors allowing them to be placed anywhere occupancy detection is needed without installing any low-voltage or line-voltage wiring. Optional coin batteries can be used if low light levels are encountered. xCella Wireless Remote Modules add additional functionality such as vacancy mode, semi-automatic mode, and adjustable time delays and will automatically adjust functionality based on the other xCella devices paired into the system.

The xCella Wireless Window/Door Sensor communicates to xCella Remote Modules or Wireless Receivers using RDT wireless technology whenever it detects a window/door has been opened or closed. It is suitable for hotel, dorm, and class rooms because the xCella Remote Modules can be programmed to disable or set back HVAC or other electric loads using delay timers and cycle limiting to help prevent over-cycling of A/C units. The Wireless Window/Door Sensor is mounted onto any standard window or doorframe and is self-powered by built-in photovoltaic cells. It is available with one or two rockers and has a 90′ maximum indoor range.

The xCella Wireless Rocker Switch communicates to xCella Remote Modules or Wireless Receivers using RDT wireless technology to deliver ON/OFF and manual dimming control. It is completely self-powered, available with one or two rockers per switch, and may be paired with an xCella Wireless system for a 90′ maximum indoor range. The xCella Wireless Rocker Switch can be stuck or screw-mounted onto any flat surface. Every transmitter is manufactured with a unique 32-bit address allowing multiple wireless switches.

The xCella Key Card Switch communicates wirelessly to an xCella system whenever a hotel key card is inserted into the switch slot. The switch is completely self-powered and is suitable for occupancy detection in hotel rooms and senior residences. When combined with other wireless devices, it can provide an affordable occupancy based solution for managing HVAC energy use. The xCella Key Card Switch harvests power from the motion of inserting and removing a hotel key card and operates on the 902 MHz ISM band frequency with a 90′ maximum indoor range.

The xCella Wireless Receiver works together with the wireless switch, occupancy sensor, door/window sensor, handheld remote, and/or photosensor. It provides one-way communication from xCella wireless switches and sensors to a GR 2400 wired system, providing wireless control over wired relay and dimming panels. The xCella Wireless Receiver is powered by the GR 2400 bus (12VDC), is wired with Cat. 5 cables and RJ45 connectors, and can be easily relocated. This enables the creation of a hybrid wired/wireless solution that can meet budget and performance requirements of a room-based project. Taking up two consecutive bus addresses, the xCella Wireless Receiver is powered by the 902 MHz frequency and can support up to 14 wireless switches, up to 14 wireless occupancy sensors, and up to six wireless photosensors.

The xCella Wireless Handheld Remote communicates to xCella Remote Modules or Wireless Receivers using RDT wireless technology to deliver ON/OFF control. It is completely self-powered, has a 90′ maximum indoor range, and measures 1.85″ x 3.15″ x .7″.

The xCella Wireless Remote Module is a load controller that uses robust distributed intelligence supported by RDT wireless technology. This intelligent relay delivers wireless communication and can be installed directly onto a fixture or junction box for branch circuit control. Available as either a switching or (0-10V) dimming relay, xCella Remote Modules also feature various inputs and outputs for connection to low-voltage occupancy sensors, photosensors, and alarm systems. When used with an xCella Wireless Gateway, Remote Modules may also be controlled by any GR 2400 Digital Time Clock. Modules are paired with wall stations and sensors using a single button and then intelligently adjust the sequence of operations automatically based on the other devices paired in the room with a 90′ maximum indoor range.

The xCella Wireless Gateway works together with all xCella wireless products to communicate with the GR2400 system for wireless control. It is powered by the GR 2400 bus (12VDC) and the unit itself is wired with Cat. 5 cables and RJ-45 connectors. The Gateway can be used to link wireless devices to a GR2400 wired system or to network together multiple wireless panels and devices. It supports up to 16 xCella relay groups (reduced if dimming) and up to 14 wireless switches, 14 occupancy sensors, and six wireless photosensors. The xCella Wireless Gateway has an internal antenna and operates on the 900 MHz ISM band frequency.
