1. Press and hold the manual occupancy override button on an FX-WRZ Series Sensor for 5 or
more seconds. In rapid transmit mode, the sensor transmits once every 10 seconds for 5
minutes, for a total of 30 update messages. After each transmission, the sensor’s occupancy
LED flashes to indicate the wireless signal strength between the sensor and the associated
parent FX-ZFR18xx Series Router.
2. In addition, when a sensor is in rapid transmit mode, the target FX-ZFR18xx Series Router’s LED
blinks to indicate the received signal strength:
3. If there is a poor signal or no signal, determine why the signal strength between the sensor
and router is not adequate for your application.
4. If there is a good or average signal, the sensor and router are communicating.
Use the sensor’s rapid transmit mode in conjunction with the FX-WRZSST-120 Wireless Sensing
System Tool to perform a site survey, test the wireless signal strength between potential device
locations, and adjust FX-ZFR device locations before installing the devices. For more information on
using the sensor’s rapid transmit mode with the tool, refer to the
FX-WRZSST-120 Wireless Sensing
System Tool Installation Instructions (Part No. 24-10563-71)
.
Manual occupancy override button
Pressing the manual occupancy override button, located on the left side of the sensor, serves
two main functions. First, it temporarily sets the space to an occupied state. Second, it checks the
wireless signal strength of the sensor. The LED on the sensor flashes 3 times to indicate a strong
signal, 2 times to indicate a good signal, or 1 time to indicate a marginal signal. For sensors with an
LCD display, a number of bars on the display indicates wireless signal strength (3 bars for a strong
signal, 2 bars for a good signal, or 1 bar for a marginal signal).
Commissioning multiple FX-WRZ Sensors
Mesh mode
You can add up to nine FX-WRZ Series Sensors for each FX-PCG, FX-PCA, or FX-PCV in mesh mode.
The Zone DIP switches on the FX-WRZ Sensor relate to the Zone Netsensor (SA Bus device) address
configured for the sensor in the Controller Configuration Tool (CCT). For example, if you set the
Zone DIP switches to a value of 3 (that is, DIP switch 1 and 2 are set to ON), you must use Zone
Netsensor address 202 in the CCT. You can add up to nine FX-WRZ Sensors for each controller. You
can use any nine of the sixteen available Zone Netsensor address settings at a time.
The
mesh
mode of operation is intended for use with the FX-ZFR18xx Series Coordinator and FX-
ZFR18xx Series Router. Table 2describes the Zone DIP switch settings for the wireless applications in
mesh mode.
