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-Wave
TM
enabled device that will send a water alert on your Z-Wave
TM
network.
Devices performing other functions and from other manufacturers can also be part of your
Z-Wave
TM
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-Wave
TM
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Information provided in this manual is for your convenience and may be superseded by updates.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-Wave
TM
Network
Program Switch for Inclusion or Exclusion
The switch is used for including or excluding the WWA-02AA in a Z-Wave
TM
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-Wave
TM
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-Wave
TM
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.
