Aquatic safety device for e.g. swimming pool, has passive units with plane structure e.g. grid, plate or thread, where thread is movable between passive position and active position, and passive position and two hyperactive positions
Résumé
The device (DSA) has passive units (MPA) with a plane structure e.g. grid, plate or thread (FIL), where the thread is movable between a passive position (POP) at a base (FON) of a swimming pool (PIS) and active position (POA) at a surface (SUR) of the swimming pool. The thread is movable between the passive position and two hyper active positions (POO, POY). Detector units (MDE) receive random test signals. Passive units, actuator units (MAC) and alarm units (MAL) are regularly tested.
