Thank you for purchasing this Wireless Water & Freeze / Temperature Alarm. This product will provide you with peace of mind and the
protection you expect. Leaking pipes, corroded water heaters, fixtures in bathrooms and laundry rooms, refrigerator drip pans, etc. can
all cause water damage. The WWA-02AA is a Z-WaveTM enabled device that will send a water alert on your Z-WaveTM network.
Devices performing other functions and from other manufacturers can also be part of your Z-WaveTM network and can act as repeaters
to extend your network range.
Functionality:
The WWA-02AA alarms when water is detected and will also provide a Z-WaveTM alarm signal when the temperature drops below a low
temperature setpoint or rises above a high temperature setpoint. The WWA-02AA functionality is based on wireless (RF)
transmissions. Any wireless transmission can be subject to RF interference and, although unlikely, this interference may
cause the unit to not operate as intended. The WWA-02AA must not be used in life support and/or safety applications.
Information provided in this manual is for your convenience and may be superseded by updates. The specifications and this
manual are subject to change without notice. It is your responsibility to ensure that the WWA-02AA meets your specifications.

Using the WWA-02AA in a Z-WaveTM Network Program Switch for Inclusion or Exclusion
The switch is used for including or excluding the WWA-02AA in a Z-WaveTM network.
Refer to your controller’s User Manual for specific details on network inclusion, exclusion, and association.
Inclusion in (adding to) a network: 1) Set up the inclusion mode at the controller; 2) Briefly press the switch once and the controller will
indicate the unit has been included in the network. Also, the LED will blink when the inclusion completes. Inclusion and exclusion are
always done at normal transmit power mode.
Exclusion from (removing from) a network: 1) Set up the exclusion mode at the controller; 2) Press and hold the switch for approx. 2
seconds until the controller indicates the unit has been removed from the network. The LED will blink when the exclusion completes.
Associations: Once in a network, a controller can be used to associate the WWA-02AA with other devices in the Z-WaveTM network,
such as a light or another remote audible alarm. Refer to your controller’s documentation on how to associate WWA-02AA with another
device in your network. The WWA-02AA supports three association groups with a maximum of 5 devices in each group. Basic Set
commands are sent at 30-minute intervals to the associated groups while alarms are active.
A Basic Set Command is sent to the associated nodes, if any, assigned to Group1 to indicate that EITHER a Water Alarm OR
Heat Alarm (under or over temperature) is active.
A Basic Set Command with value = 0xFF is sent to the associated nodes, if any, assigned to Group2 to indicate that a Water
Alarm is active. When the water alarm is cleared by drying the contacts, one additional report with value = 0x00 is sent.
A Basic Set Command is sent to the associated nodes, if any, assigned to Group3 to indicate that a Temperature Alarm (over or
under temperature) is active. When the temperature alarm is cleared due to temperature change, one additional report with value =
0x00 is sent.
Node Info / Keep-Alive: While not in a network, the WWA-02AA will send the Z-WaveTM Node information frame when the switch is
briefly pressed. This is primarily used for inclusion as described above. The node information frame will also be sent while in network
when the switch is pressed and held for 2 seconds. In either case, the WWA-02AA will ‘stay awake’ for approximately 30 seconds after
this to allow time for configuration commands from the controller. Refer to Status indications below for LED feedback.
Wakeup Notification: The WWA-02AA will wakeup and send a notification every 4 hours (default) to allow a controller to query and
update the status of the unit. A brief switch press while in network will also cause the WWA-02AA to wakeup and send a notification.
The device stays awake for 5 seconds during this time or longer if communicating with the controller.

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-WaveTM 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-WaveTM network (if included in the network).
Also, depending on your Z-WaveTM 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 paper
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-WaveTM network using your controller. Examples of Z-WaveTM controllers can be found on the FortrezZ website
(www.fortrezz.com).
Battery / Low Battery
The WWA-02AA will send an alert on the Z-WaveTM 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 monitor 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.
