ZFR1800 Series Wireless Field Bus System Technical Bulletin 63
Testing Wireless Signal Strength between WRZ Series Sensor and ZFR1811
Router
To test the wireless signal strength between a WRZ Series Sensor and ZFR1811
Router, ensure that the sensor and router are powered on and communicating by
momentarily pressing and releasing the sensor occupancy override button. If the
sensor occupancy LED flashes after the button is released, the sensor and router
are communicating. See Table 19 for what each LED flash rate indicates.
Note: If the LED does not flash, you must determine why the sensor and router
are not communicating. See Troubleshooting.
On LCD models, the signal strength is shown on the display on the face of the
sensor (callout in Figure 20).
For information on using the optional ZFR Checkout Tool (ZCT) to see the
wireless signal strength of all of the various ZFR1800 Series System devices, refer
to the Using the ZFR Checkout Tool (ZCT) chapter of the Controller Tool Help
(LIT-12011147). For information on using the optional WRZ-SST-120 Wireless
Sensing System Tool and any WRZ Series Sensor to test wireless signal strength,
refer to the WRZ-SST-120 Wireless Sensing System Tool Installation Instructions
(Part No. 24-10563-12).
