Functions
The water presence detection system consists of an inset detector and a wall sensor in
radio frequency at the frequency of 868 MHz.
The water sensor detects the presence of water by operating using ultrasounds.
This technology prevents oxidation of the contacts due to humidity and therefore avoids
untimely interventions.
The Chorus flood protection system for domestic use allows users to:
• handle one or more water detectors using an RF connection.
• detect the presence of water by installing sensors.
• the use of an internal relay to trigger a solenoid valve with manual reset to intercept the
delivery of the water at the point of supply.
• signalling the alarm by means of an audible warning and a light signal.
