To establish wireless RF associations in One-to-One Wireless Sensing applications, you must assign and configure the same, unique RF address on the FX-WRZ7860 Receiver and the FX-WRZ Series Sensor or sensors associated with that receiver.
The RF address for an FX-WRZ7860 Receiver is configured manually by positioning the numbered switches on the TRANSMITTER ID address DIP switch block and the AREA address DIP switch block on the receiver. See Setting the FX-WRZ7860 Receiver RF Address.
The RF address (TRANSMITTER ID and AREA) for each FX-WRZ Series Sensor associated with an FX-WRZ7860 Receiver must match the receiver RF address. The FX-WRZ Series Sensor’s RF address is configured by positioning the numbered switches on the TRANSMITTER ID DIP switch block and the AREA address DIP switch block on the sensor. See Setting the FX-WRZ Series Sensor RF Address.
The RF TRANSMITTER ID and AREA DIP switch blocks on the sensor and receiver are binary switch blocks. The TRANSMITTER ID switches on each switch block are assigned numbers (1, 2, 4, 8, 16, 32, 64, and 128). The TRANSMITTER ID address is a number from 0 to 255, which is equal to the sum of the numbers of the switches that are in the ON position. As an example, placing Switches 1, 4, 8, and 32 in the ON position establishes a TRANSMITTER ID address of 45 for the device.
The AREA address switches on each switch block are assigned numbers (1, 2, 4, and 8). The AREA address is a number from 0 to 15, which is equal to the sum of the numbers of the switches that are in the ON position. Typically, the AREA address may be used to distinguish different floors, wings, or areas of a building. Together, the TRANSMITTER ID and AREA DIP switches provide 4,096 unique RF addresses.
In multiple-sensor applications, two or more FX-WRZ Series Wireless Sensors have the same TRANSMITTER ID and AREA addresses, but are distinguished by the SENSOR # selection on the FX-WRZ Series Wireless Sensor. The SENSOR # may be 199, 200, 201, 202, or 203.
If the FX-WRZ7860 Receiver fails to respond to an FX-WRZ Series Wireless Sensor with a matching RF address, the receiver may have already locked onto another sensor with the same RF address. To clear the receiver from an incorrect association, while the receiver has power, momentarily change the receiver’s RF address to a different RF address and then back again to the original RF address.
Never use the same RF address (TRANSMITTER ID and AREA) for two receivers that are in the same building or general location. RF signals can reflect off objects or pass through glass windows, and it is possible for RF signals to travel between buildings or reach receivers several floors away.
