Manual occupancy override button
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 WRZ Sensors
Mesh mode
You can add up to nine WRZ Series Sensors to each
Controller in the mesh mode.
The Zone DIP switches on the 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
with DIP switch 1 and DIP switch 2 set to ON, you must
use Zone Netsensor address 202 in the CCT. You can add
up to nine WRZ Sensors to each field 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 ZFR or ZFR Pro Series Coordinator and ZFR or ZFR
Pro Series Router. Table 2 describes the Zone DIP switch
settings for the wireless applications in mesh mode.

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 WRZ Series Sensors to each
WRZ-7860 receiver in the one-to-one mode.
The one-to-one mode of operation is intended for use
with the WRZ-7860 Receiver. For one-to-one mode, Figure
5 shows DIP switch settings.
