Ha4619 - LEGRAND 3440 Technical Sheet

Radio flooding detector
Description
This device generates an alarm signal when the contacts of the corresponding sensor
make contact with water.
The signal is then processed by the alarm central unit, which activates the siren and the
Telephone communicator (if installed), for sending a telephone message.
Better protection can be ensured by installing a relay actuator within the Burglar-Alarm
system, which will order an electrovalve to shut off the main water supply in case of
flooding.
Two front pushbuttons can be used to interrupt the alarm signalling and to test the
operation of the sensor.
