Choosing a mounting location
The WWA-02AA is suitable for use in dry, interior locations only. Avoid placing the unit close to a metal frame, or other metal
enclosures that may affect RF range. Place the unit so that any leaks that may occur will not drip directly on the unit.
Recommended WWA-02AA uses: Under sink, Next to Sump pumps, Water Heaters, Laundry Room, Bathroom Floor, Storage Area,
Garage, Utility Sink, Vacation/Recreation homes, Boats, etc.
During an alarm
If water is detected at the monitoring location or an over/under-temperature conditions is detected, the unit will send an alert
message(s) to the Z-Wave
TM
network (if included in the network). The type of alert message depends on how the WWA-02AA is
configured. If associations are configured, Basic Set messages will be sent as described above under
Associations
. If Water or Heat
Alarms have been configured (via Alarm Command Class V2 Set commands), then the WWA-02AA will send alert messages to the
Node ID that configured the alarm. Association alert messages and Alarm alert messages may both be configured and sent. Drying
the sensor contacts will clear the Water Alarm. If an over/under temperature Alarm occurred and the temperature alarm conditions are
no longer present, an ‘alarm clear’ message is also sent to the Z-Wave
TM
network (if included in the network).
Also, depending on your Z-Wave
TM
controller, it is possible to receive a remote alert. For example, with some gateway controllers, you
can receive an email or cell phone text message when an alarm is activated. Depending on your specific controller’s capabilities you
will be able to remotely check the status of any WWA-02AA in your network.
Testing the WWA-02AA
Moisten a paper towel and place over both of the small metal pads on the water sensor until you observe two quick LED blinks. The
water alarm indication may take up to 4 or 5 seconds. If the LED fails to blink, your battery may be old or dead or incorrectly installed,
the sensor may not be moist enough, or the water sensor may be damaged. If you see the LED blink, remove the moistened pape r
towel and clean the small metal pads of any water residue and the LED should blink four times. You can then add the WWA-02AA to
your Z-Wave
TM
network using your controller. Examples of Z-Wave
TM
controllers can be found on the FortrezZ website
(
www.fortrezz.com
).
Battery / Low Battery
The WWA-02AA will send an alert on the Z-Wave
TM
network at regular intervals when it detects a low battery condition. In addition, it
will periodically blink the LED. Your controller may be able to be configured to monito
r the unit’s wake up notifications. If these stop,
then this might also be an indication that the battery has died or that transmissions from the WWA-02AA are no longer being received.
After a water leak, please ensure that there is no moisture in the unit and around the battery. Do not install batteries that appear
damaged or unsealed. When replacing batteries, the water seal may be broken around the screws. After screwing the parts back
together, the use of some sealant, such as silicone caulk, around the screws is recommended.
Configuring the WWA-02AA
The high and low temperature setpoints in the WWA-02AA can be configured. The low temperature setpoint must always be set at
least two degrees below the high temperature setpoint. The low temperature setpoint cannot be set less than
–10 degrees C and the
high temperature setpoint cannot be set greater than 70 degrees C. The temperature setpoints can be configured via a ‘smart’
controller after inclusion; details are provided in the technical appendix.
Temperature Reports
If your controller sends the wakeup interval set command, the controller will also become the Wakeup Master node. The WWA-02AA
will automatically send temperature reports to this Wakeup Master node within a half hour of a 1 degree C change in temperature.
