Connection to a Zigbee gateway

The water leak detection device communicates with the gateway.
The gateway executes the rule or automation you have established and sends a close signal to the valve.

Requires:

• Permanent Internet connection
• Compatible Zigbee gateway
• Smartphone or tablet

5V / 5W (included)

Backup power source*

4 AAA lithium batteries (not included)
Uninterruptible power supply ACUPS-01 (not included)

** IMPORTANT: Your Wi-Fi router and Zigbee Gateway must be connected to an Uninterruptible Power Supply (UPS) so that the valve closes when a leak is detected.

In case of power failure, the signal between the water leak detection device and your gateway Zigbee will not be possible.
The close signal won't be able to reach the valve.
For optimum protection, even in the event of a power failure, the Sedna VA4220WF-K5 water damage protection system is preferred.
