WATER ALARM

Sampling every 4 seconds

Z-Wave
TM
transmissions (eve
ry approx. 30 minutes while alarm is active): ‘Basic Set’ with Value = 0xFF sent to associated nodes in Group 1
and/or Group 2 and/or an Alarm Command Class V2 Water Leak Report (Event = Water Leak Detected, Unknown Location, 0x02AA with Alarm
Level = 0xFF. What is sent depends on whether associations are configured and/or Water Leak Alarm is enabled with a non-zero destination
Node ID (see Alarm Factory Default State under OTHER below).

Visual indication of water alarm via LED

Alarm Command Class V2 Get (Sensor Type = 0x05, Water Leak) can be used to request water alarm state
 When water alarm is no longer active, sends ‘Basic Set’ with Value = 0x00 to association nodes as above and/or Alarm Command Class Water
Leak Report (Unknown Event, 0xFE) with Alarm Level = 0x00
UNDER-TEMPERATURE / OVER-TEMPERATURE ALARM

Sampling every 4 seconds with averaging algorithm

Sensor has an accuracy of approx. +/-2 degC. Default alarm trigger points set at approx. 4 degC and 70 degC

Z-Wave
TM
transmissions (every approx. 30
minutes while alarm is active): ‘Basic Set’ with Value = 0xFF sent to associated nodes in Group 1
and/or Group 3 and/or Alarm Command Class V2 Heat Report with Alarm Level = 0xFF and Event = [Overheat Detected, unknown location,
0x02AA or Underheat Detected, unknown location, 0x06]. What is sent depends on whether associations are configured and/or Heat Alarm is
enabled with a non-zero destination Node ID (see Alarm Factory Default State under OTHER below).

Visual Indication of temperature alarm via LED

Alarm Command Class V2 Get (Sensor Type = 0x04, Heat) can be used to request heat alarm state
 When temperature alarm is no longer active, sends ‘Basic Set’ with Value = 0x00 to association nodes as above and/or sends Alarm Command
Class Heat Report (Unknown Event, 0xFE) with Alarm Level = 0x00
BATTERY STATUS
 Battery level percentage estimated based on number of Wakeup1’s (see below) since battery insertion

In addition, battery voltage readings can trip the low battery state

Low battery report (Battery Command Class) every approx. 30 minutes after low battery becomes active

Visual indication of low battery every approx. 40 seconds
WAKEUPS

Wakeup1: Power saving design wakes up every 4 seconds to test water and freeze sensor

Wakeup2: Once every approx. 4 hours (default) unit wakes up to send a notification either to a wakeup node or broadcast. The unit stays awake
for approx. 5 seconds or while communicating with a controller. Sensors are not checked during this time.

The Wakeup node is the node configured to receive the Wakeup Notification command. This is set in the WWA-02AA by the Wakeup Interval
Set command and is typically the Controller node. Only one value for the wakeup interval, the default interval of 0x003840 (4 hours), can be set.
MULTILEVEL SENSOR

Multilevel Sensor Report sent with current Temperature (Degrees C) in response to Multilevel Sensor Get command

Unsolicited Multilevel Sensor Report sent to Wakeup Node within 30 minutes of a 1 degree temperature change (if Wakeup node is set); filtering
is applied to avoid ‘oscillating’ report transmissions and conserve battery life; transmission is independent of a Wakeup Notification
CONFIGURATION

Parameter 1 sets Low Temperature Trigger Point (degrees Centigrade, 1 signed byte, Default = 4)

Parameter 2 sets High Temperature Trigger Point (degrees Centigrade, 1 signed byte, Default = 70)
KEEP-ALIVE

Switch activated causes 30 sec RF receiver-on time intended for Controller configuration after network inclusion

Sensors not checked during Keep-Alive time
OTHER

Alarm Factory default state = Enabled; unsolicited alarm reports (underheat, overheat, and water leak) will be sent to Node 0x01 (after inclusion).
This Node ID can be changed via the Alarm Set Command (Alarm Command Class V2)

All Network Inclusions / Exclusions are at normal power levels

Up to 5 nodes allowed in each association group

Basic Report sent in response to a Basic Get with value equal to Multilevel Sensor Type (Temperature, 0x01)

Built with Z-Wave
