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
The PIR sensor DCH-Z122 has PIR sensor function,based on Z-Waveâ„¢ technology.
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.
Reset to factory default
This device also allows to be reset without any involvement of a Z-Wave controller. This procedure should only be used when the primary controller is inoperable.
There is a button on DCH-Z122. 1. Pressing button for about 5 seconds. 2. IDs are excluded and all settings will reset to factory default. Notice: Use this procedure only in the event that the primary controller is lost or otherwise inoperable.
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
There is a button on DCH-Z122. 1. Have Z-Waveâ„¢ Controller entered inclusion mode. 2. Pressing button once to enter the inclusion mode. 3. After add successful, the device will wake to receive the setting command from Z-Waveâ„¢ Controller about 20 seconds.Exclusion
There is a button on DCH-Z122. 1. Have Z-Waveâ„¢ Controller entered exclusion mode. 2. Pressing button once to enter the exclusion mode.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: There is a button on DCH-Z122. Press the button once, the device will awake 10 seconds.
Quick trouble shooting
Here are a few hints for network installation if things dont work as expected.
- Make sure a device is in factory reset state before including. In doubt exclude before include.
- If inclusion still fails, check if both devices use the same frequency.
- Remove all dead devices from associations. Otherwise you will see severe delays.
- Never use sleeping battery devices without a central controller.
- Dont poll FLIRS devices.
- 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.
Association Groups:
| Group Number | Maximum Nodes | Description |
|---|---|---|
| 1 | 8 | Z-Wave Plus Lifeline |
| 2 | 8 | light control |
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.
Parameter 10: Auto Report Battery Time
