Abra leakage protection - How does it work?

A modern kitchen might have a lot of water connections (sink, dish-washer, refrigerator, coffee machine etc.) and is vulnerable for leakages and water spill. Without a floor drain and a water membrane, a leakage can cause severe damage to floor, walls and kitchen furniture. 

This installation detects and prevents bigger leakages and it satisfies the Norwegian building regulation for water installations (TEK17 §15-5 - Requirement for automatic leakage detection and water shut-off system in wet rooms)

Water is detected by Water Sensor Tape and the Linkbox+ will automatically close the valve (1/2" or 3/4" mounted on the kitchen water intake) and the water supply.  The system alerts the user immediately with sound, light and push-notification in the Abralife app.

The system also allows the user to control the valve manually (physically or via app) if needed (e.g. longer absence from the home or cabin).

The Waterguard valves perform an automatically exercise if not used in 7 days. This ensures a healthy and operational valve.

	Abralife App	Abralife er ditt grensesnitt mot Abra-universet. Her kan du gjøre alt fra å monitorere strømforbruk til å styre lys og sjekke status på vannsikring.
	Linkbox+ (central unit)	Linkbox+ (central unit) is mounted in a suitable location in the kitchen cabinetry or utility room using the included wall bracket and connected to power via the included adapter. The included CAT6 cable is connected between the central unit and valve, and the central unit
	Ball valve 1/2" or 3/4"	The valve is installed by a certified plumber on the kitchen's cold water intake.
	Sensortape for water	Self-adhesive sensor tape is connected to the central unit and pulled down under the kitchen carcass and along the floor where water is assumed to collect in case of spills or leaks. It is important that the surface is clean so that the sensor tape adheres well to the substrate!
	WaterSensor+ Wireless water sensor	WaterSensor+ is a wireless sensor that registers the presence of water, monitors temperature and humidity, and alerts if risk of frost. If water is detected, the sensor will inform the Linkbox+ and the water supply will immediately be shut off. The users will be notified via a light and sound alarm and a Abralife app push notification.
