Anyone who owns a pool knows that it’s an absolute necessity for a homeowner to secure it against entry, especially when there’s children or pets in the household. Unsupervised pools present a drowning hazard, so the pool owner must take whatever steps they deem necessary to keep unsupervised use of the pool from happening. One of the ways that a pool can be secured is by using state-of-the-art alarms that can alert adults when the pool has been accessed.

Using a variety of safeguards and alarms can ensure that the pool is safer for everyone in the household. To help our readers secure their pools, we’ve discovered ten of the best pool alarms and listed them below. Using one or several of these alarms can be a great way for anyone to ensure the security of their pool and the safety of anyone using it.

9Poolguard DAPT-2 Water Hazard Alarm

When used with other pool sensors and alarms, this water hazard door alarm is a wonderful addition to any pool area. It’s designed to be attached to the door that opens out into the pool area, so parents know when a person has entered the pool area. It will sound approximately 7-seconds after the door has been opened and will continue to sound until an adult has reset the alarm at the door. This product is a great addition to any pool security system and it is another tool that goes along quite nicely with other pool alarms such as shock alarms and water vibration alarms.

8Poolguard PGRM-2 In-Ground Pool Alarm

buy

This Poolguard alarm system is designed to always be on guard when it’s installed on in-ground pools up to 800 square feet in size. Once installed, it is completely tampered proof and can’t be deactivated because it remains in alarm mode at all times. It also sounds an alarm when it’s removed from the pool as well. As vigilant as this product is, however, the pool owner can still use the pool by placing it into sleep mode. When the alarm sounds on this system, it’s 85-decibels at 10-feet, so people can usually hear it from a distance of up to 200-feet.

7LifeBuoy Pool Motion Sensor

buy

This Lifebuoy alarm is designed to be used not only in a person’s home pool but is also designed to be mobile so that it can be used in other pools as well. It’s capable of being used in this way because it used an advanced pool detection algorithm that detects waves when something enters the pool. It uses a state-of-the-art central processing unit and several sensors to detect movement in the water. It also has a swim mode that allows movement in the water, but if it detects no movement for approximately 10-minutes, then it will automatically switch to alarm mode. That allows the pool to be used while still ensuring this device is protecting children and pets.

6Pool Eye Above Ground Alarm

buy

The Pool Eye Pool Alarm is a system that uses a specialized underwater wave detector to ensure that everyone in the household is safe. Whenever anyone 15-pounds of heavier enters the pool, this device detects the underwater waves caused by it and then emits a loud alarm. This product only takes about 10-minutes to assemble and can be quickly attached to a 24-foot round or 16×32-foot oval above ground pools. It operates using 4 AA batteries, which don’t come with the unit and is easy to operate. No wonder this alarm from Pool Eye has been used for almost 2 decades by conscientious pool owners.

5Safety Turtle 2.0 Child Immersion Alarm Kit

buy

This child immersion water alarm kit is designed a bit differently than some of the other pool alarms we’ve covered thus far. This kit features a wristband that has a whimsical turtle shape to it and is put on the child’s wrist. When that wristband comes into contact with water, it will then sound the alarm from the base unit. This is a simple way for parents to know when their child has entered the pool. It doesn’t require any special programming, is easy to set up and has a range of approximately 200-feet. And since multiple turtle wristbands can be added to each base unit, one can be used for everyone in the family.

4Pool Patrol PA-30 Alarm

buy

This pool alarm is designed to be easy to set up and to provide the pool owner with many, many years of service. It’s designed for both in-ground and above-ground pools, and it comes with all of the hardware needed for proper installation. The alarm goes into the pool, and the receiver is designed to go into the house. After this alarm has been set up, it will sound an alarm if something enters or falls into the pool and creates a wave. It will detect this wave and deliver the alarm to the receiver, which can be located up to 200-feet away.

3Blue Wave Poolwatch Alarm System

buy

This product is designed to attach to the pool deck and to go partially into the water. Once it’s been set up, it will then trigger an alarm whenever an object weighing over 18-pounds enters the pool. It doesn’t matter if the object is a child, pet or intruder, anyone weighing over that weight will set off the alarm. And since this product has a receiver with a 100-foot wireless range, the alarm can not only be received around the pool but can also be received inside the home as well. That makes it a great tool for any pool owner to use around their pool to keep their children and pets safe.

2Pool Shock Alarm

buy

Although this alarm system won’t alert the pool owners to a child or a pet entering the pool, it will provide a benefit that’s just as important. When used in the water, this product will sound an alarm whenever an electric current is detected in the pool’s water. Electric Shock Drowning, also known as ESD, is a form of drowning that occurs after a person has received an electric shock in a pool and it’s something that’s not as rare as most people think. It doesn’t take a whole lot of current to knock a person unconscious and cause them to drown, so everyone with a pool should protect themselves and their family by using this device.

1Swim Time Pool Eye Alarm System

buy

This comprehensive pool alarm system comes with an in-home remote receiver that alerts the homeowner when something weighing over 15-pounds has entered the pool. When that happens, which the system interprets as a pet or child entering the pool, it will sound an 85-decibel alarm at not only the pool but also at the receiver. Since the receiver can be placed up to 100-feet from the pool, that gives parents a good head’s up if someone enters their pool without their knowledge. This is a product that’s suitable for both in-ground and above ground pools that are up to 18×36-feet in size.

A Guide To Pool Alarms

Consumers need to give careful consideration to any alarm they use for their pool area. That’s because these alarms are true lifesavers when they’re used according to directions. Unfortunately, far too many people fail to purchase the best pool alarm, fail to install it correctly or fail to keep it in good operation. And the result of those failures can be a drowned child or pet.

To help our readers buy a pool alarm that’s right for them, we’ve decided to write this little guide. This is a guide that will explain how to buy the right alarm and the differences between some of the alarm types. Now let’s wade right into the depths of this guide and find out how to choose the best pool alarm for your pool.

Door & Window Alarms

These alarms are designed to sound an alarm when a window or door facing the pool area is open. In that regard, these are not officially pool alarms but they do form an important protective layer around the pool that consumers should consider. The best models are water and weather-resistant, sound an alarm that’s over 100-decibels, and has an adult bypass feature that’s placed out of reach of children and/or pets. And they should also have a UL-rating to ensure that they’re safe to use around the pool area.

Fence/Wall Mounted Alarms

Another category of pool alarms we would like to discuss are the ones that are placed on a wall or fence that may be surrounding a pool. Instead of using direct sensors, these alarm systems use infrared beams or magnetic connections that set off the alarm if someone passes through it. Although these models are cheaper than models that mount directly on the pool, we don’t recommend that consumers use this alarm by itself. Instead, we feel that this type of alarm is best used in conjunction with other models. That way, if neighborhood kids jump the fence to bypass this alarm, they will have to contend with another alarm on the pool.

Surface Wave Detection

As the name would most aptly suggest, this type of pool alarm is designed to float on top of the pool’s surface. When a pet or a child falls into the pool, they create waves that set off the alarm when they touch certain contacts on the unit. These models are easy to set up and extremely easy to use. They’re also extremely effective, especially when used in conjunction with other types of alarms. If these alarms have a downside, it’s the fact that if there’s heavy wind or rain, then it can certainly cause the alarm to go off falsely. The alarm can also be falsely set off by falling branches and other objects. And of course, before the pool can be used, it has to be removed from it.

Subsurface Wave Detection

The name of this pool alarm says everything you need to know about it. It’s an alarm that sits right below the surface of the water. How does it work? It works by monitoring pressure changes in the water that are caused by waves. A child or a pet falls into the water and the waves generated by that action then cause a change in water pressure. The alarm then picks up those changes and sets off the alarm. The main benefit of these pool alarms is that they’re less likely to be set off falsely and are usually equipped with a sensitivity level that can be adjusted. Another benefit of these devices is that they can be used underneath solar covers or in spas. The main disadvantage of these pool alarms is that they have to be physically attached to the side of the pool, and that’s very often not possible with an above ground pool that has soft sides.

Personal Immersion Detectors

The next type of pool alarm that we would like to discuss is personal immersion detectors, otherwise known as P.I.Ds. These alarms are either worn by a child as a wristband or are affixed to a pet’s collar. This device is then attached to a remote alarm that sounds if the band gets wet. The main benefit of these personal pool alarms is that they continue to work, even as other people are swimming in the pool. And once water contacts the wristband, it immediately sounds an alarm. This is a device that requires no installation or set up to work. And because of the way it works, it will operate in any size pool, spa or even in the ocean. The main drawback of these alarms is that they could potentially be set off while the child is washing their hands. They may also be set off from moisture from other sources such as rain, spilled drinks, etc.

Some Final Advice: Layering Protection

The last thing we would like to talk about is how these devices should be used. Although some people think that if they buy one or two of these devices, then they’re child or pet is protected, we have another take on the subject altogether. In our opinion, it’s best to layer several different types of devices possible, along with other protective measures such as padlocks for gates, and window or door locks.

A multi-layered pool alarm system is the best way to protect children or pets from falling into a pool. That means equipping alarms on all entrances to the pool area and using either surface or subsurface wave detectors in the pool. For us, that’s the absolute minimum security a pool area should have. That way, consumers can make sure their kids and pets are as safe as humanly possible.

A Few Final Tips

It’s also a good idea to follow good practices when using pool alarms. This means doing the following:

  • Reading the alarm’s instructions.
  • Properly installing the alarm.
  • Making sure the alarm’s batteries are operational.
  • Test the alarm regularly to make sure it’s still working properly.
  • Never leave a child unsupervised in a pool area.
