The invention concerns a device signalling the fall of a person into a water expense comprising a sealed hollow floatable housing (1), wherein is provided a motion sensor (2) adapted to produce a trigger signal when a movement is detected and an alarm signal transmitter (6) associated with the motion sensor (2) and capable of receiving from the latter the trigger signal and transmitting the alarm signal in response. The motion sensor (2) comprises a balance weight (2a) arranged elastically suspended in a tubular guide (2b) fixed to the housing (1), said balance weight (2a) mobile in said tubular guide (2b), in the lower part, being provided with at least a switch element (3) designed to be urged in contact with the balance weight (2a) by an ascending movement of the housing (1) and deliver through said contact the trigger signal.
Device signalling the accidental fall of a person into a water expanse, such as a swimming-pool, comprising a sealed hollow housing (1) able to float containing firstly a motion sensor (2) able to produce a trigger signal when a movement is detected, and secondly a transmitter (6) for transmitting an alarm signal associated with the motion sensor (2) and able to receive from the motion sensor (6) the trigger signal and transmit in response the alarm signal, characterised in that the motion sensor (2) includes a balance weight (2a) placed elastically suspended in a tubular guide (2b) extending upwards and fixed to the housing (1), said balance weight (2a) being able to move inside this tubular guide (2b) and said guide (2b) under the balance weight (2a) spaced from the latter and being provided with at least one switch element (3) intended to come into contact with the balance weight (2a) via an ascending movement of the housing (1) and via this contact deliver the trigger signal.
Signalling device according to one of the preceding claims, characterised in that the balance weight (2a) is made of a ferromagnetic material and is placed inside the magnetic field produced by a magnet (8) placed under the switch element (3) in the axis of the tubular guide (2b).
Signalling device according to one of the preceding claims, characterised in that the lower portion of the housing (1), at least below the floating plane, has a convex shape.
Signalling device according to one of the preceding claims, characterised in that the housing (1) projecting under its lower face comprises several stop elements (7) for keeping the body of the housing spaced from the suction opening by coming into support against the border of said opening.
Signalling device according to one of the preceding claims, characterised in that the central zone of the lower face of the housing has a cavity.
