Possible Cause Troubleshooting Step and Remedy
SH1 A WRS Series Sensor is installed instead of a
WRZ Sensor.
1. Remove the cover of the sensor.
2. On the inside of the plastic cover, read the
product code. If it does not start with WRZ, the
sensor does not work in this system.
3. Replace sensor with an equivalent WRZ
model.
SH2 The PAN OFFSET switch of the WRZ Sensor
does not match the PAN OFFSET switch of a
ZFR1811 Router.
1. Ensure that the PAN OFFSET switches on the
ZFR1811 Routers match the PAN OFFSET
switches on the ZFR1810 Coordinator.
2. Ensure that the PAN OFFSET switches on the
WRZ Sensors match the PAN OFFSET
switches on the ZFR1810 Coordinator.
SH3 The ZFR1811 Router on the associated WEFC is
not installed, powered, or on the PAN.
1. Check the MS/TP device address on the
sensor, and the WEFC match.
2. Check that the router is installed/connected.
3. Check that the router and WEFC are
powered.
SH4 The WRZ Sensor battery power is low and its
batteries need to be replaced.
Replace the batteries.
SH5 The WRZ Sensor is not installed. Install the sensor and ensure settings are correct.
SH6 The factory calibration jumper (J5) is not installed. Ensure jumper is installed correctly on both pins.
