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 wake up interval is a tradeoff between maximal battery life time and the
desired responses of the device.
The device will stay awake right after inclusion for 10 seconds allowing the controller to perform certain configuration. It
is possible to manually wake up the device by pushing button 2 in management mode. The minimum allowed wake up
time is 240s but it is strongly recommended to define a much longer interval since the only purpose of a wake up
should be the reporting of the battery status or an update of the child protection settings. The device has a periodic
wake up function however this function is disabled by the configuration parameter #25. This will protect the battery in
case the controller is accidently configuring a wake up interval. A wake up of the KFOB outside the range of the
controller will lead to lots of unsuccessful communication attempts draining the battery. Defining node ID of 0 as a
destination of the Wake Up Notification will disable the periodical wake up function as well.
It is possible to set the node ID to 255 to send Wake Up Notifications as broadcast. In this mode device takes more
time to go to sleep and drains battery faster, but can notify all its direct neighbors about a wake up.
Node Information Frame
The Node Information Frame (NIF) 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 are 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.
Pressing button 2 in management mode will issue a Node Information Frame.

Associations
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 happens
all devices stored in the respective
association group will receive a common wireless command.
Association groups
1
Lifeline (max. nodes in group: 10)
2
Control Group A, controlled by button 1 or single clicks of buttons 1 and 3 (max. nodes in group: 10)
3
Control Group B, controlled by button 2 or single
clicks of buttons 2 and 4 (max. nodes in group: 10)
4
Control Group C, controlled by button 3 or double clicks of buttons 1 and 3 (max. nodes in group: 10)
5
Control Group D, controlled by button 4 or double clicks of buttons 2 and 4 (max. nodes in group
: 10)
Set and Unset Associations to Actuators
Associations can be assigned and remove either via Z-Wave commands or using the device itself. To control a Z-Wave
device from the KFOB the node ID of this device needs to be assigned to one of the four association groups. This is a
three-step process:
1.
Turn the KFOB into management mode and hit button 4 within 10 sec. (LED is blinking green when
management mode is reached).
