Presentation
System for detecting the immersion or fall of a body, adaptable to the edge of an in-
ground, semi-in-ground or above-ground swimming pool, maximum 12 x 5 in size
(range : 7 meters).
Beyond that, we recommend equipping the pool with additional protective measures
complying with French standard NF P90-307/A1.
Following standard NFP 90-307/A1, your alarm is congured for a rectangular pool 4
x 8 m in size and 1.40 m depth (the most widely used type of pool in France).
Gre By Visiopool® can be used in pools up to 5 x 12 m in size.
Gre By VISIOPOOL® analyzes the movement of the water in your pool and knows how
to distinguish interference waves (cascade, ltering, rain, wind) from those emitted
by the falling of a body. The response time is proportional to the distance between
the point of detection and the point of immersion.
Warning ! The installation and use of an alarm system is no substitute for your
personal vigilance. The Gre By VISIOPOOL® is an additional tool to human vigilance
for supervision of pools.
This method is no substitute for the attention of adults.
Supervise your children carefully!
Limits of Use
• You can use the alarm Gre By VISIOPOOL® only if the pool installation allows
complete intervention (including rescuing in the pool) in under 3 minutes from the
house or place of accommodation.
• The standard NFP 90-307/A1 relating to pool alarms species the detection of any
fall within a maximum time of 12 seconds : therefore the Gre By VISIOPOOL® may not
be situated more than 7 meters away from any potential fall site.
In order to make large sized pools compliant, you may have to install one or more
additional Gre By VISIOPOOL® alarms.
• The safety, alarm and fault signals must be audible from the house or place of
accommodation. This must be veried during installation.
• Shape and equipment of the pool: For pools of unique shape or in the case of large
pools (close to 12 x 5 meters), only an onsite test can verify the compatibility of the
Gre By VISIOPOOL® with your equipment.
Warning: some pool equipment may be incompatible with the proper functioning of
