About this task

To prepare the WRZ-STR0000-x Series Transmitter for operation, and to reinstall the transmitter housing on its mounting base, complete the following steps:

Procedure

  1. Place the appropriate DIP switch overlay based on the application over the DIP switches. See Figure 1 through Figure 3.
    Figure 1. Mesh network application DIP switch overlay

    Figure 2. Non-mesh network, one-to-one application DIP switch overlay

    Figure 3. Back of WRZ-STR0000-x Series Transmitter showing DIP switches and batteries

  2. Set the DIP switches located on the back of the transmitter.

    For a mesh network application using a ZFR and ZFR Pro Series Router, see Preparing the WRZ-STR0000-x Series Transmitter for operation and set the DIP switches as indicated in Figure 1. Refer to WRZ Series Wireless Room Sensors Installation Guide (24-10332-2) for information on how to commission multiple WRZ Series Sensors in a ZFR18xx Series Wireless Field Bus System.

    1. Set the POWER switch to OFF.
    2. Set the MODE switch to MESH.
    3. Set the PAN OFFSET switches in accordance with the job or system plans.
      Important: Ensure that the PAN OFFSET is the same for each ZFR or ZFR Pro Series Coordinator, ZFR or ZFR Pro Series Router, and WRZ-STR0000-x Series Transmitter in a mesh network.
    4. Set the ZONE DIP switches to match the Zone Number in the Controller Configuration Tool (CCT) software. Each Zone Number corresponds to the SA bus address as shown in Table 1.
      Table 1. Setting the ZONE DIP switches
      Zone number SA bus address
      0 199
      1 200
      2 201
      3 202
      4 203
      5 204
      6 205
      7 206
      8 207
    5. Set the MS/TP ADDRESS DIP switches to match the MS/TP address of the controller that the transmitter intends to communicate with.
    6. Set the TRANSMIT LEVEL switch to 10 mW.

      For a non-mesh network, one-to-one application that uses a WRZ-78x0-0 Receiver, see Figure 2 and set the DIP switches as indicated. Ensure that the AREA and TRANSMITTER ID switches on the WRZ-78x0-0 Receiver and the WRZ-STR0000-x Transmitter are set to the same value.

    1. Set the POWER switch to OFF.
    2. Set the MODE switch to 1 to 1.
    3. Set the SENSOR # to 199 for applications with only one transmitter for each controller. Use the other settings for additional transmitters in applications with a single controller. Refer to the WRZ Series One-to-One Wireless Room Sensing System Technical Bulletin (LIT-12011641) for information about how to commission multiple WRZ-STR0000-x Series Transmitters in a WRZ-78x0-0 One-to-One Wireless Room Temperature Sensing System.
    4. Set the AREA switches to match the AREA switch on the WRZ-78x0-0 Receiver.
    5. Set the TRANSMITTER ID switches to match the TRANSMITTER ID on the WRZ-78x0-0 Receiver.
  3. Install the two supplied AA alkaline batteries into the battery compartment on the back of the transmitter. Ensure to install the batteries in the correct polarity. See Figure 3.
  4. If the address DIP switches are set to the correct positions and the temperature sensing system is ready for operation or testing, set the POWER DIP switch to the ON position. See Figure 1 or Figure 2.
  5. Align the tabs on the bottom edge of the transmitter mounting base with the slots on the bottom edge of the transmitter housing, and rotate the transmitter assembly onto its mounting base. Reverse the procedure shown in Figure 1.
  6. Use a 1/16 in. (1.6 mm) Allen wrench or Johnson Controls T-4000-119 Allen-head adjustment tool to tighten the tamper-resistant set screw and secure the transmitter assembly onto its mounting base. See Figure 1.

Results

Press and release the signal test button on the WRZ-STR0000-x Series Transmitter to initiate a signal strength test with the associated ZFR or ZFR Pro Series Router, or WRZ-78x0-0 Receiver. See Removing a mounting base installed with double-sided adhesive foam tape. The signal strength is shown on the LCD on the face of the transmitter. See Figure 4.

Use an optional WRZ-SST-110 Wireless Sensing System Tool as a site survey tool with the WRZ-STR0000-x Series Transmitter before installation, to determine potential installation locations for system devices and to determine the wireless signal strength between the system devices in the application.

Refer to the WRZ-SST-110 Wireless Sensing System Tool Installation Instructions (Part No. 24-10563-12) for more information on testing signal strength.
