Facility Explorer One-to-One Wireless Room Sensing System Product Bulletin1 Refer to the QuickLIT website for the most up-to-date version of this document.The Facility Explorer One-to-One Wireless Room Sensing System enables RF room sensors to wirelessly communicate to FX-PC Series Programmable Controllers (FX-PCA, FX-PCG, and FX-PCV). This One-to-One Wireless Room Sensing System is the functional equivalent of an NS Series Network Sensor, but it eliminates all the hard wiring between the room sensor and the controller.The two main components of this system are the FX-WRZ Series Wireless Room Sensor and the FX-WRZ7860-0 Receiver. Depending on the model, the FX-WRZ Series Sensor can transmit sensed temperature, temperature setpoint, sensed humidity, occupancy status, and low battery conditions. FX-WRZ Series Wireless Room Sensor models are available with or without an LCD, and are designed for indoor intra-building applications only.Several models of FX-WRZ Series Wireless Room Sensors include an onboard passive infrared (PIR) occupancy sensor that detects motion to determine if a space is occupied. This feature maximizes up to 30% energy savings in high-energy usage environments such as schools, dormitories, offices, and hospitals by adjusting the temperature of the space based on the occupancy status. In addition, the PIR occupancy sensor facilitates trending of floor space usage in these environments.The FX-WRZ7860-0 Receiver acts as an interface between the FX-WRZ Series Wireless Room Sensors and the FX-PC Series Programmable Controller. The FX-WRZ7860-0 receives the data from the FX-WRZ Series Wireless Sensors, and passes it onto the FX-PCSeries Programmable Controller over its Sensor Actuator (SA) Bus.In a typical application, one FX-WRZ Series Wireless Room Sensor reports to one FX-WRZ7860-0 Receiver; however, you can associate up to five FX-WRZ Series Wireless Room Sensors with a single FX-WRZ7860-0 Receiver. In these multi-sensor applications, the receiver passes all of the room sensors’ data to the FX-PC Series Programmable Controller. You can then configure the FX-PC Series Programmable Controller to either average the room sensors’ temperature and humidity inputs, or select the highest or lowest sensed temperature and humidity for control of the target zone. Figure 1: Facility Explorer One-to-One WirelessRoomSensingSystemTable 1: Features and Benefits (Part 1 of 2)FeaturesBenefitsOne-to-One Wireless RF DesignEnables quick, economical, and low-maintenance installations, which reduce installation and wiring costs.Stylish, Lightweight Wireless Room Sensors with Occupancy Override Button Make installation simple and provide room temperature, humidity, setpoint temperature, occupancy status, and low battery conditions to FX-PC Series Programmable Controllers (FX-PCA, FX-PCG, and FX-PCV).60-Second Transmission IntervalsGreatly extend sensor battery life, and enable continuous operation over the life of the batteries (approximately 4 to 5 years) while maintaining an even temperature in the controlled zones.Facility Explorer One-to-One Wireless Room Sensing SystemProduct BulletinFX-WRZ7860-0Code No. LIT-12011664Issued October 25, 2013Supersedes June 5, 2012Facility Explorer One-to-One Wireless Room Sensing System Product Bulletin2ApplicationIn a typical application, the FX-WRZ7860-0 Receiver forwards (by means of the SA Bus) zone data sent by an FX-WRZ Series Wireless Room Sensor to any one of several FX-PC Series Programmable Controllers. As an example, in a VAV application, the FX-WRZ Series Wireless Room Sensor sends zone conditions to the FX-WRZ7860-0 Receiver, which passes that data to an FX-PC Series Programmable VAV Controller. OperationThe Facility Explorer One-to-One Wireless Room Sensing System comprises one or more FX-WRZSeries Wireless Room Sensors and an FX-WRZ7860-0 Receiver that receives wireless RF data from the sensor, and provides zone control data to specified FX-PC Series Programmable Controllers in building HVAC systems. The FX-WRZ Series Wireless Room Sensor and FX-WRZ7860-0 Receiver combination is functionally equivalent to a network sensor, such as an NS-BTP7001-0, minus the communication wiring typically located inside the wall.Like a network sensor, the FX-WRZ7860-0 Receiver is designed to communicate over an SA Bus interface via BACnet® Master-Slave/Token-Passing (MS/TP) protocol with FX-PC Series Programmable Controllers. The receiver supplies the sensed zone temperature, humidity, temperature setpoint, and occupancy override data.The FX-WRZ7860-0 Receiver uses direct-sequence, spread-spectrum RF technology and operates on the 2.4 GHz industrial, scientific, and medical (ISM) band. The receiver meets the IEEE 802.15.4 standard for low power, low duty-cycle RF transmitting systems. An FX-WRZ7860-0 Receiver operates as a transceiver to create a bidirectional association with an FX-WRZ Series Wireless Room Sensor.Built-in Integral Wireless Signal Strength Testing Provides quick, easy, visual indication of the wireless RF signal strength between a sensor and associated receiver, helps locate optimum device positions during installation, and aids in troubleshooting.Multiple Sensor Temperature Averaging and High/Low SelectionEnhance zone temperature control by enabling up to five sensors to report to a single receiver, which allows the controller to average the sensor temperature or select the highest or lowest temperature value to control the zone.Onboard PIR Occupancy Sensor Available on Some Wireless Room SensorsMaximizes up to 30% energy savings in high-energy usage environments, and facilitates trending floor space.Compact, Easily Installed ReceiverReceives sensed temperature, humidity, setpoint, and low-battery condition from an FX-WRZ Series Wireless Room Sensor, and interfaces directly with an FX-PC Series Programmable Controller.Simple DIP Switch SettingsProvide easy commissioning and up to 4,096 unique receiver addresses.Optional, Battery-Powered Wireless Sensing System ToolProvides wireless mobility to check for best RF link and determine optimum receiver mounting locations.High Resistance to RF Interference from Other Radio Devices or RF Noise SourcesResults from application-based frequency agility, which allows for automatically changing to a different channel to avoid RF interference and missed messages.Optional RepeaterExtends the operating range between a sensor and a receiver.Blinking LED Light to Indicate Firmware VersionFive seconds after the power is applied, the red LED flashes to indicate the firmware revision. For example, firmware revision 3 is indicated by the LED flashing three times during the startup process.Table 1: Features and Benefits (Part 2 of 2)FeaturesBenefitsIMPORTANT:Use the Facility Explorer One-to-One Wireless Room Sensing System only to provide an input to equipment under normal operating conditions. Where failure or malfunction of the room sensor or receiver could lead to personal injury or property damage to the controlled equipment or other property, additional precautions must be designed into the control system. Incorporate and maintain other devices, such as supervisory or alarm systems or safety or limit controls, intended to warn of or protect against, failure or malfunction of the room sensor or receiver.IMPORTANT:The Facility Explorer One-to-One Wireless Room Sensing System is not designed or intended for use in mission-critical or life/safety applications.Facility Explorer One-to-One Wireless Room Sensing System Product Bulletin3For installations where the RF signal path between the sensor and receiver provides unsatisfactory results, locate an FX-ZFR1811, which serves as a repeater, between the sensor and the receiver.Refer to the Facility Explorer One-to-One Wireless Room Temperature Sensing System Technical Bulletin (LIT-12011663) for information on commissioning the FX-WRZ7860-0 Receiver and configuring One-to-One Wireless Room Sensing Systems.DimensionsSee Figure2 for FX-WRZ7860-0 Receiver physical features and dimensions.
