What is Z-Wave?

Z-Wave is the international wireless protocol for communication in the Smart Home. This
device is suited for use in the region mentioned in the Quickstart section.

Z-Wave ensures a reliable communication by reconfirming every message ( two- way
communication) and every mains powered node can act as a repeater for other nodes
( meshed network ) in case the receiver is not in direct wireless range of the
transmitter.

This device and every other certified Z-Wave device can be used together with any other
certified Z-Wave device regardless of brand and origin as long as both are suited for the
same frequency range.

If a device supports secure communication it will communicate with other devices
secure as long as this device provides the same or a higher level of security.
Otherwise it will automatically turn into a lower level of security to maintain
backward compatibility.

Product Description

This sensor monitors leakage and sends an alarm when flooding or leakage is detected. The sensing device can be away up to 3 m from the main device. The unit can be mounted on every flat surface. The installation can be done with screws or double-sided tape.

The ST812 is a battery-powered device, which is in non-operating state unless an action is detected. After a programmable sleeping time the device wakes up and sends status information. After this the unit goes back to non-operating state. Batteries can be changed without unscrewing the device from the door or frame. The unit will give a visual warning on the device and sends a warning to the Z-Wave controller, when batteries need to be replaced. The units send information to a controller or any other associated Z-Wave device. Up to 4 devices can be controlled from this device.

The device needs to be included into a Z-Wave network by a remote control or any other Z- Wave controller. For configuration of certain behavior a static controller such as a PC with home automation software or a gateway is recommended.

Prepare for Installation / Reset

Please read the user manual before installing the product.

In order to include (add) a Z-Wave device to a network it must be in factory default
state. Please make sure to reset the device into factory default. You can do this by
performing an Exclusion operation as described below in the manual. Every Z-Wave
controller is able to perform this operation however it is recommended to use the primary
controller of the previous network to make sure the very device is excluded properly
from this network.

Safety Warning for Batteries

The product contains batteries. Please remove the batteries when the device is not used.
Do not mix batteries of different charging level or different brands.

Installation

1. Release the Sensor from the mounting plate and the battery cover by removing the fixing screws.

2. Put the 3 * AA 1.5V batteries in the battery compartment.

3. For mounting use mount plate and the screws.

4. Refit the device to the back cover and secure with the fixing screw.

A clean smooth surface is required to mount the Flood Detector securely. The length of flood sensor cable is 3 meters. If a 3-meter cable is too long, roll up the cable and fasten it by twist ties. The transceiver should be placed as high up as possible on the wall to improve communication and to prevent it from coming into contact with water in case of flooding.

Inclusion/Exclusion

On factory default the device does not belong to any Z-Wave network. The device needs
to be added to an existing wireless network to communicate with the devices of this network.
This process is called Inclusion.

Devices can also be removed from a network. This process is called Exclusion.
Both processes are initiated by the primary controller of the Z-Wave network. This
controller is turned into exclusion respective inclusion mode. Inclusion and Exclusion is
then performed doing a special manual action right on the device.

Inclusion

Make sure that your Z-Wave Controller is in the Inclusion-/Exclusion-Mode. Click three seconds on the tamper switch (Z-Wave Button) behind the mounting plate to confirm the process.

Exclusion

Make sure that your Z-Wave Controller is in the Inclusion-/Exclusion-Mode. Click three seconds on the tamper switch (Z-Wave Button) behind the mounting plate to confirm the process.

Product Usage

1. When water is detected, the orange LED of Detector will flash one second every one minute and beep 30 seconds and transmit radio signal to controller (option) simultaneously. In normal mode, the Detector is allowed to be activated once in one minute, avoiding false trigger.
2. When water is released, the green LED on the Detector will illuminate once and emit radio signal to controller (option).
3. When the battery level on the Detector drops to a certain level, the red LED will flash once every 30 seconds and radio signal will be transmitted to controller (option). Please follow the Battery Installation directions replacing the batteries as soon as red LED appears.

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 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. To issue a NIF execute the following action:

Click three seconds on the tamper switch (Z-Wave Button) behind the mounting plate or a detected action by the sensor sends a Node Information Frame.

Communication to a Sleeping device (Wakeup)

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. To wakeup the device please perform
the following action:

Click three seconds on the tamper switch (Z-Wave Button) behind the mounting plate or a detected action by the sensor will wake up the device and keep it awake.

Quick trouble shooting

Here are a few hints for network installation if things dont work as expected.

1. Make sure a device is in factory reset state before including. In doubt exclude before include.
2. If inclusion still fails, check if both devices use the same frequency.
3. Remove all dead devices from associations. Otherwise you will see severe delays.
4. Never use sleeping battery devices without a central controller.
5. Dont poll FLIRS devices.
6. Make sure to have enough mains powered device to benefit from the meshing

Association – one device controls an other device

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 the same wireless command wireless command, typically a ‘Basic Set’ Command.

Explanation of Z-Wave specific terms

• Controller — is a Z-Wave device with capabilities to manage the network.
  Controllers are typically Gateways,Remote Controls or battery operated wall controllers.

• Slave — is a Z-Wave device without capabilities to manage the network.
  Slaves can be sensors, actuators and even remote controls.

• Primary Controller — is the central organizer of the network. It must be
  a controller. There can be only one primary controller in a Z-Wave network.

• Inclusion — is the process of adding new Z-Wave devices into a network.

• Exclusion — is the process of removing Z-Wave devices from the network.

• Association — is a control relationship between a controlling device and
  a controlled device.

• Wakeup Notification — is a special wireless message issued by a Z-Wave
  device to announces that is able to communicate.

• Node Information Frame — is a special wireless message issued by a
  Z-Wave device to announce its capabilities and functions.
