Product Usage; Water Leakage Detection; Link Testing; Node Information Frame - Aeotec Water Sensor 7 Pro Quick Start Manual

Exclusion
1. Open the housing.
2. Press the tamper on the side of the appliance three times quickly.

Product Usage

Once installed the sensor will report Leakage Detected and No Leakage status changes to a central Z-Wave
controller using notification commands. Additionally, the sensor can directly control other devices using the
association group 2. The device is protected by a tamper switch.
The device contains two sensors with the following accuracy measures:
•
Humidity: ± 3% RH (max), 0– 80% RH
•
Temperature: ±0.4 °C (max), – 10 to 85 °C

Water leakage detection

The water leakage detection allows reporting as soon as water hits the sensor probe. This is accomplished
using the command class notification - water alarm - water leakage detected unknown location. After the
leakage has stopped (the sensor probes are not short-connected through the water) the device reports this to
the central controller.

Link testing

When activated by configuration parameter #4 the device can perform a link test with device No.1. Double-
clicking the tamper will start the process. As a result, the GREEN LED will blink one time in case of success
and RED LED will blink three times in case of failure.
The device sends the following notifications to the central controller:
•
Water Leakage Unknown Location (0x05 - 0x02)
•
Tamper Removed (0x07 - 0x03)
•
Replace Battery Now (0x08 - 0x0b)

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: Press the tamper once

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

Firmware-Update over the Air

This device is capable of receiving a new firmware 'over the air'. The update function needs to be supported by
the central controller. Once the controller starts the update process, perform the following action to confirm the
firmware update: Wake Up the device by removing the cover. Then hit the tamper switch once.
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
