Johnson Controls WRZ-SST-120 Installation Manual

Applications
The WRZ-SST-120 Wireless Sensing System Tool is a
lightweight, portable, wireless receiver designed to receive
wireless Radio Frequency (RF) data transmissions from
Johnson Controls WRZ Series Wireless Room Sensors in
®
one to one sensing system site survey applications. The
WRZ-SST-120 Tool can also serve as an RF signal tester or
site survey tool before installation of a ZFR18xx Wireless
Field Bus System (ZFR181x, ZFR182x, ZFR183x).
Before installation, use the WRZ-SST-120 Tool to verify
the optimum locations for WRZ Series Sensors and the
WRZ-7860-0 Receiver in one to one wireless room sensing
systems, or for Johnson Controls ZFR18xx Routers, ZFR or
ZFR Pro Series Coordinators, Routers, Repeaters, and WRZ
Series Sensors in wireless field bus applications.

Installation
Transport the WRZ-SST-120 Wireless Sensing System
Tool in the original container to minimize vibration and
shock damage to the receiver. Do not drop the receiver or
subject it to physical shock.
Verify that all the parts shipped with the receiver:
• One WRZ-7860-0 Receiver with two magnets attached
• One battery pack with two magnets attached
WRZ-SST-120 Wireless Sensing System Tool
• One installation guide
• Two AA alkaline batteries
Setup and adjustments
Important: If there are other wireless mesh
networks or one to 0ne wireless room sensing
systems in the area, ensure that the PAN OFFSET
address of the WRZ-7860-0 Receiver and WRZ Series
Sensor, set by the TRANSMITTER ID and AREA DIP
switches, is different from the PAN OFFSET address
of those wireless mesh networks or one to one
wireless room sensing systems.
Note: Before you proceed, check that the power
switches on the WRZ-7860-0 Receiver and WRZ Series
Sensor are set to OFF.
