Use the ZFR-HPSST-0 High Power Survey tool to check signal strength and expected communications performance between the various field controllers, WRZ and NSW8000 Sensors, TEC31xx Series thermostat controllers, and the WRG Gateway. The ZFR-HPSST-0 survey tool is a special mode of the ZFR1831 Router used to test both ends of the wireless communication link. Both 100mW and 10mW transmission power signal strengths can be tested.
Note: Two ZFR-HPSST-0 are required to perform a site survey, one on each side of expected
transmission path.
If a site survey is deemed required, a checklist is available in the Wireless Best Practices Document (LIT-12013552) of information that can be used to determine how best to lay out the wireless network, how many devices are needed, and the best locations for installation.
