Use the one-to-one application DIP switch overlay in the one-to-one mode of operation, or the mesh application DIP
switch overlay in the mesh mode of operation. The switch numbers described in this table refer to the numbers on the
overlays.
One-to-One mode
You can add up to five FX-WRZ Series Sensors for each FX-WRZ7860 receiver in the One-to-One
mode.
The
one-to-one
mode of operation is intended for use with the FX-WRZ7860 Receiver. For one-to-
one mode, Figure 4 shows DIP switch settings.
Repair information
If the FX-WRZ Series Wireless Room Sensor fails to operate within its specifications, replace the unit.
For a replacement sensor, contact the nearest Johnson Controls representative.
Batteries
The two AA alkaline batteries supplied with the FX-WRZ Series Sensor typically have a life of 5 years
or more. The sensor reports a low battery condition to the receiver or controller, which relays the
low battery condition to the system.
Battery strength can also be checked at the FX-WRZ Series Sensor by pressing and holding the
manual occupancy override button (Figure 1). If the battery level and signal strength LED at the
sensor is on while pressing and holding the button, the battery power is acceptable. If the LED is
off while pressing and holding the button, the battery power is low and the batteries need to be
replaced.
On LCD models, the low battery condition is shown by
Lo bAt
flashing in the display on the face of
the sensor.
Note:
When replacing batteries, replace both batteries at the same time. Batteries removed
from this device must be recycled or disposed of in accordance with local, national, and
regional regulations. Only certified technicians or qualified building maintenance personnel
should service Johnson Controls products. Lithium batteries with a maximum cell voltage of 1.5
volts can be substituted to extend the period between battery replacement. Do not mix lithium
and alkaline batteries in this device.
