Diagnostics and Troubleshooting
Testing Battery Status
Initiate a battery status test as follows:
• On the WZS, push the Test button on the sensor (see
location on Figure 87, p.

Check Signal Strength on a Site
Use the wireless sensor system to check the signal strength 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 strength as indicated by LED1, LED2, and LED3 on
model WZS (see Figure 87, p.
model WDS (see Figure 88, p.
For more information on interpreting the LEDs and the display
symbols that indicate signal strength, see
Strength," p. 99.

Battery Type
Equipment Damage!
The batteries are manufactured in a ready-to-use state.
They are not designed for recharging. Recharging can
cause battery leakage or, in some cases, can cause the
safety release vent to open.
Equipment Damage!
Do not attempt to hook up the sensor to a power
supply. Equipment damage may result.
Use two non-rechargeable 1.5 V lithium AA batteries in the
sensor. To maintain UL rating, use only UL-listed lithium
batteries. The sensor ships with Energizer
already installed. Replacement batteries are available at Trane
Service Parts Centers (p/n X13770035010) or other local
suppliers.
Battery Life
Battery life is five years under normal conditions. If the sensor
is not used for an extended period of time, do one of the
following:
• Set the sensor address to 000 to place the sensor into a
low-power hibernation mode.
• Remove the batteries
100.
