ambient illumination is lower than preset value. If a person moves within or across the device field of vision,
a trigger radio signal will be transmitted e.g. to turn on the connected lightings for better illumination.
When the detector is first time powered up it is not included in a Z-Wave network and has no Associations.
For Inclusion or setting an Association, the device has to be brought in the relevant mode and the
inclusion/exclusion switch has to be clicked fast three times. The sensor supports two association groups,
the first for one device (alarm) and the second for up to five devices (home automation).
Wakeup Intervals - how to communicate with the device?
W
This device is battery operated and turned into deep sleep state most of the time to save battery
life time. Communication with the device is limited. In order to communicate with the device, a static
controller C is needed in the network. This controller will maintain a mailbox for the battery operated devices
and store commands that can not be received during deep sleep state. Without such a controller,
communication may become impossible and/or the battery life time is significantly decreased.
This device will wakeup regularly and announce the wakeup state by sending out a so called Wakeup
Notification. The controller can then empty the mailbox. Therefore, the device needs to be configured with
the desired wakeup interval and the node ID of the controller. If the device was included by a static
controller this controller will usually perform all necessary configurations. The wakeup interval is a tradeoff
between maximal battery life time and the desired responses of the device.
Tripple click on the little button behind the battery cover or a detected action by the sensor will wake up the
device and keep it awake.
It is possible to set the node ID to 255 to send wakeup notifications as broadcast. In this mode device takes more time to
go to sleep and drains battery faster, but can notify all it's direct neighbors about a wakeup.
Node Information Frame
NI
The Node Information Frame is the business card of a Z-Wave device. It contains information
about the device type and the technical capabilities. The inclusion and exclusion of the device is confirmed
by sending out a Node Information Frame. Beside this it may be needed for certain network operations to
send out a Node Information Frame.
Tripple click on the little button behind the battery cover or a detected action by the sensor sends a Node
Information Frame.
Associations
A
Z-Wave devices control other Z-Wave devices. The relationship between one device controlling
another device is called association. In order to control a different device, the controlling device needs to
maintain a list of devices that will receive controlling commands. These lists are called association groups
and they are always related to certain events (e.g. button pressed, sensor triggers, ...). In case the event
