Using Safety Turtle in Salt Water Pools
A higher concentration of salt in your pool reduces the ability of
the Turtle to communicate with the Base Station. The salt increases
the pool's conductivity, thus increasing the power loss of a radio signal
passing through a given height of water.
Therefore, for a salt chlorinated pool, the Base Station is best located
pool side, at least 3 feet (1 meter) above the water surface. [An Extended
Range System is then required to accomplish alarming in the house.]
Depending on distance [and physical obstructions] between where the
Turtle is immersed and the Base Station, beeping in test mode may stop
(indicating the signal is lost) before the Turtle reaches the recommended
test depth of 4-6 inches. If a child free falls into this pool, the
Turtle may not have time to transmit before the signal is effectively
blocked.
Reducing the distance [and physical obstruction] to the Base Station
will increase the achievable Turtle test depth.
For maximum safety when using with pools, the Turtle wristband should
be locked on your child's wrist, not attached to another part of his/her
anatomy or clothing. In the eventuality the alarm is not triggered on
the way down, buoyancy, weight distribution and involuntary arm movement
will still result in alarming within 5 - 10 seconds.
Most salt-water chlorinator manufacturers recommend that salt concentration
not exceed 3,600 ppm. Terrapin also recommends that your salt concentration
be measured and kept within recommended limits.
