BlueFox Pool Safety Born from Swiss research into ultrasonic, BlueFox detects potential drowning situations and provides instant alert to swimming pool owners, operators or life guards. The system can easily be installed in existing or new pools. BlueFox optimizes the protection of families and pool users from potential tragedies. As a result, pool operation will be safer, providing pool owners with peace of mind. BlueFox System Components: BlueFox consists of one or muitple alarm detection sensors fitted below water level in the pool and acoustic, visual or mobile alarms units. A crucial component is the BlueFox wrist computer worn by persons in or around the pool. BlueFox currently offers three different versions of the system: BlueFox Mobile System, BlueFox Private Pool System and BlueFox Public Pool System. How does BlueFox Work? An alarm detection sensor located below water level in the pool constantly monitors for ultrasonic signals transmitted by BlueFox wrist computers worn by persons in the pool. The completely waterproof wrist computers contain pre-programmed parameters for depth and time that allow for pool enjoyment within desired safety limits. A breach of the pre-programmed parameters will trigger the wrist computers to send out an ultrasonic alarm signal. As soon as the alarm detection sensor is detecting a wrist computer alarm signal, it will trigger the acoustic, visual or mobile alarms (optional for BlueFox mobile and public pool safety systems). Setting Safety Parameters: The BlueFox user-friendly wrist computer software can be downloaded free of charge from the www.deepbluemarine.ch website. The software offers standard safety parameters suitable for different user profiles. Wrist computers can also be programmed to fit any individual user safety parameter requirement i.e. for respective swimming competence or other safety requirements. BlueFox wrist computers can be used in all pools equipped with the BlueFox pool safety system as they are automatically recognized by any BlueFox pool sensor.
