Europe.

To run this device please insert fresh *1 3V Lithium** batteries.

Please make sure the internal battery is fully charged.

The device will fit into Water Meters from Sensus (http://sensusesaap.com/). To confirm inclusion and exclusion put a magnet on the flat side of the sensor for 3 seconds until the red LED is blinking. To send out a NIF or to wake up the device follow the same process.

Important safety information

Please read this manual carefully. Failure to follow the recommendations in this manual may be dangerous or may violate the law.
The manufacturer, importer, distributor and seller shall not be liable for any loss or damage resulting from failure to comply with the instructions in this manual or any other material.
Use this equipment only for its intended purpose. Follow the disposal instructions.

Do not dispose of electronic equipment or batteries in a fire or near open heat sources.

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

SWM 301 is a battery-powered RF module using Z-Wave”® technology for reporting water metering from SENSUS water meter (http://sensusesaap.com/). The RF module records the meter reading by backlash-free pick-up on the litre wheel of the meter register and transmits the data over the Z-Wave network either on a time or delta change. Choose the position where the unit is to be mounted, avoid locations alongside or behind large metal surfaces that could interfere with the low-power radio signals between the unit and the Controller. The unit contains a lithium battery which provide a 10 years battery life based on a 24hr reporting interval.

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

Just snap in the sensor in to the position beside the meter digit display. The device will fit into Water Meters from Sensus (http://sensusesaap.com/). It may also be applicable to other manufacturers meters but this is not supported by the manufacturer.

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

To confirm inclusion and exclusion put a magnet on the flat side of the sensor for 3 seconds until the red LED blinks.

Exclusion

To confirm inclusion and exclusion put a magnet on the flat side of the sensor for 3 seconds until the red LED blinks.

Product Usage

The meter readings are transmitted by wireless and can be read by any Z-Wave controller.

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:

Put a magnet on the flat side of the sensor for 3 seconds until the red LED blinks. Water meter will then send NIF after 15 seconds.

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:

To wake up the device put a magnet on the flat side of the sensor for 3 seconds until the red LED blinks.

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.

Configuration Parameters

Z-Wave products are supposed to work out of the box after inclusion, however
certain configuration can adapt the function better to user needs or unlock further
enhanced features.

IMPORTANT: Controllers may only allow configuring
signed values. In order to set values in the range 128 … 255 the value sent in
the application shall be the desired value minus 256. For example: To set a
parameter to 200 it may be needed to set a value of 200 minus 256 = minus 56.
In case of a two byte value the same logic applies: Values greater than 32768 may
needed to be given as negative values too.

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.
