Everything you Need to Know about Above-Ground Pool Alarms

If you have an above-ground pool in your backyard, a pool alarm is one of the most effective ways to prevent unsupervised children or pets from drowning.  Many people mistakenly think that above-ground pools are less of a drowning risk than in-ground pools because they sit high off the ground.  In reality, a non-swimmer or animal is just as much at risk of drowning in an above-ground pool as they would be in any type of pool or body of water.

A pool alarm is a device that sounds an alert as soon as someone enters the water so adults nearby have a chance to intervene before it’s too late.  Most pool alarms are designed for either above-ground or in-ground pools. This article discusses the different types of above-ground pool alarm systems, how they work and the advantages and disadvantages of each.

Surface Wave Detection

A surface wave detection pool alarm floats on the water’s surface. When a child or pet falls into the pool, the waves created by the fall trigger the alarm.

How it Works:  This type of pool alarm incorporates an electrical circuit that includes two contacts. One contact rests in the water and the other contact (above-surface contact) rests above the water. When the above-surface contact is touched by water from a surface wave, the electrical circuit is completed and an alarm sounds.

Advantages:  Easy to set up, requires no installation. Battery powered (usually 9V or AAs). Sensitive to low weights; good for protecting small pets. Also works in spas and in-ground pools.

Disadvantages:  Some models are prone to false alarms caused by wind and heavy rain or falling leaves, branches and objects. Must be removed during swimming.

Remote receiver can work with home security systems.

 

Subsurface Wave Detection

Subsurface wave detection pool alarms detect movement below the surface of the water.

How it Works:  This type of pool alarm uses below-water sensors that are activated by wave-induced pressure changes. There are two basic designs: one relies on the movement of a magnetic float below a magnetic sensor and the other relies on a pressure-sensitive switch.

Advantages:  More consistent in alarming and less likely to false alarm than surface wave detection alarms, per a study performed by the U.S. Consumer Product Safety Commission (CPSC). Do not have to remove during swimming. Adjustable sensitivity. Also works in spas and in-ground pools. Can be used with a solar cover.

Disadvantages:  Most models require installation onto the side of the pool, which is not always possible for soft-sided (inflatable) above-ground pools.

Immersion Detector Wristband

This pool alarm activates when a person or pet wearing a special wristband or pet collar falls into the water, which sounds a remote alarm.

How it Works:  The wristband or pet collar is fastened securely on the wrist or around the animal’s neck. An alarm alert at a separate base station is triggered when the battery-powered sensor on the wristband or collar is immersed in water, such as when a child falls into the pool. Child-sized wristbands come with a locking key to prevent the child from removing the band.

Advantages:  Provides continuous protection to the wearer with no risk that the unit has been deactivated while others are swimming or the pool is being cleaned. Alarms immediately. No setup or installation. Portable — can be used on a boat or brought on vacation. Works in all sizes of pools or spas.

Disadvantages:  Alarm could activate and false alarm when the wristband becomes wet from normal activities like washing hands or walking in the rain. Does not protect children or pets who are not wearing special wristbands or collars.

No installation required. Comes with 12-month warranty on base station and accessories; 6-month warranty of turtle sensors.

 

Increase Your Layers of Protection

Pool alarms provide invaluable protection for children and pets and are often required by law.  For an additional layer of protection, your pool alarm should be used in conjunction with other types of alarms — such as a gate alarm, window alarm and door alarm — which will alert you when an unsupervised child or pet first enters the pool area and before they get near the water.
