Operation, Maintenance, and Troubleshooting
The Wireless Zone Sensor set supports star (*) and double star (**) on the sensor
thumb wheel (Figure 19, p.
Note: Consult the appropriate unit control module for information about this
function.
Follow these steps to check the signal quality on a site:
1. Power up a receiver with a 24 V transformer (user supplied)
2. Associate the sensor to a receiver of the same model intended for the job
3. Place the receiver at the desired location
4. Place or hold the sensor at the desired location
5. Press the Test button (S5) on the sensor and observe the signal quality as
indicated by LED1, LED2, and LED3
For more information on interpreting the LEDs that indicate signal quality,
see "Signal Quality Test, " p.
The maximum output power level of a Wireless Zone Sensor set is controlled by
software and restricted by channel of operation and agency requirements per
country or region. The sensor has a default maximum power level of 10 mW, but
the receiver determines the ultimate output power level of the sensor.
The Wireless Zone Sensor set has two receiver models available:
• X13790488: 100 mW for North American use
• X13790489: 10 mW for international use
If receiver model X13790488 is used, the system power level for the sensor will
be increased from 10 mW to 100 mW after it has been associated with the
receiver. If receiver model X13790489 is used, the system power level for the
sensor will be limited to 10 mW.
Note: If initial association of a sensor with receiver model X13790488 is
unsuccessful, try re-attempting association after moving the sensor closer
to the receiver. After association, the system power level will increase to
100 mW and the sensor can be relocated farther away.
