Leckage-Protection Offline for Gate Valves
SKU: KFRFLO01
Version: 1.0
↑1. Product Description
The offline leakage protection system 'KFRFLO' detects water leaks using multiple
water sensors distributed throughout the house and shuts off the water supply in the
event of a leak. The unique feature of this system is that it does not require an app,
internet, or Wi-Fi.
The retrofit motor is installed in place of the handwheel on the main shut-off valve.
The product bundle includes three battery-operated water sensors that are paired with
the motor and distributed around the house.
Communication between the sensors and the motor uses the highly reliable, standardized
LoRa wireless technology, specifically designed for such applications. No additional
equipment like a gateway is needed. All sensors communicate directly with the motor in
case of an alarm, making the system installation very straightforward.
In the event of an alarm, the affected sensor emits a loud audible signal and flashes
red. The motor shuts off the water, also emitting an audible signal and flashing red.
The alarm can be cleared, and the water turned back on by pressing the button on the
motor.
