WRZ-SST-120 Wireless Sensing System Tool
Use the WRZ-SST-120 Wireless Sensing System Tool
with a WRZ Series Sensor as a site survey tool to
determine the wireless signal strength between a
ZFR1810 Coordinator and a ZFR1811 Router or
between two ZFR1811 Routers. Refer to the
WRZ-SST-120 Wireless Sensing System Tool
Installation Instructions (Part No. 24-10563-12)
for
more information on testing signal strength in your
application.

OFF Steady
= No power (or normal operation for more than 2 hours).
OFF Steady with 1 Flash every 10 seconds
= ZFR1811 Router is not a member of a
wireless network, invalid PAN OFFSET setting, no ZFR1810 Coordinators or ZFR1811
Routers in area.
ON Steady with Signal Strength displayed once every 10 seconds
= ZFR1811 Router
is a member of a wireless network.
OFF Steady with Signal Strength displayed once every 10 seconds
= Wireless network
is actively communicating, but ZFR1810 Coordinator cannot be reached (for example,
coordinator lost power).

Rapid Flashes for 5 minutes
= rapid flashes occur for up to 5 minutes:
•
when the Reform Network option is initiated to the network, the ZFR1811 Router
disconnects itself from the network
•
when the PAN OFFSET is changed on the ZFR1811 Router
•
when the PAN OFFSET is changed on the ZFR1811 Router after it has already joined
another PAN
•
when the Channel Mask in the ZFR1810 is changed from CCT

Ping
Wireless node
function in the
network
Network pings provide a means of physically locating connected devices. There are two
methods with different use cases:
1) Use ZFR Checkout Tool (ZCT) to ping an address. This LED on the connected ZFR1811
to blink, indicating the device mapped to that specific MS/TP address
2) Press the Occupancy pushbutton on a WRZ Network Sensor. This causes the blinking
response on the ZFR1811 connected to the paired device. This can be used to validate
switch settings on the sensor during installation.

The Signal Strength LEDs on all the ZFR1811 Routers in a network extinguish after approximately 2 hours of normal
operation, making the ZFR1811 less distracting when installed in an open area. To re-enable the ZFR1811 LEDs for
troubleshooting purposes, perform a scan using the ZCT or push the Network Optimize/Reform Push Button on the
ZFR1810 Coordinator.
