Introducing the latest in
water damage protection.
NOWA 4S is a fourth-generation water leak detection and control system. Including many improvements in design, functionality and safety, NOWA 4S has been entirely designed to be simple and safe. And it is 100% compatible with NOWA's PRESENCE service.
It's anything but complicated.
A new, modern look. A sleek design that fits in with any style of home. But the simplicity of NOWA 4S is not just a matter of appearance. The system has been designed to make life easier for users and installers.
Data continuity and security
Unlike previous generations of systems that all communicate via Wi-Fi, NOWA 4S uses the power and reliability of a cellular network to sync your system with the portal in real time.
Benefit from a two-year limited warranty on the NOWA 4S system.
Stopped instantly. Notified instantly.
NOWA 4S informs you immediately by notification or email that a leak has been stopped. You know the specific time and exact location of the leak. You are brought directly to the right place to correct the problem at source without having to waste time localizing the leak.
Keep things in hand, wherever you are.
You’re far from home and you forgot to shut off the water main? Thanks to the NOWA 4S app, you can remotely control the opening and closing of your main water valve. Turn it off if needed, then turn it on again when you’re back home.
A SMART APP
Streamlined interface. Easy to install. Enjoyable to use. The app simplifies your life and gives you full control at your fingertips. Available for free for iOS and Android devices.
Always tested. Always ready!
The system generates routine self-tests by itself. This ensures that the valve and all sensors are operational when it really counts.
Daily detection tests
The control panel initiates the sensors to check if they are working properly. The minute one of the sensors does not respond to the test, you are notified with the precise information.
Weekly shutoff tests
The control panel commands the electric ball valve to make one complete revolution. This simple rotation keeps the ball free of accumulated deposits and extends the valve's life by over 100 years.
Very long-life batteriesThe high-performance lithium batteries built into NOWA sensors offer a 10-year life span—a standard that is rarely equalled. The system alerts you that a battery is reaching its end of useful life before it fails.
EVEN MORE HIGH-PERFORMANCE FEATURES
All NOWA systems are known for their high detection reliability, versatility and ease of use.
Pinpoint freeze detection
The NOWA sensor's built-in temperature sensor watches out for freezing wherever you want it to. You’re notified of a risk of freezing if the temperature goes below 5°C (41°F).
Mini probes and perimeter cables increase your coverage area in hard-to-reach areas. You might for instance want to closely monitor the entire circumference of your water heater.
Just water. Not dampness.
Sensors detect water, not the normal humidity variations found in houses or commercial buildings. No need to manage unnecessary valve shutoffs.
Protection from oxidation
Sensor probes are gold plated to prevent oxidation. Their reliability is ensured, even after many years of protecting the building from damaging leaks.
