We’re also going to go over whether pool safety alarms are required by law, the different types available, and the best pool alarm systems you can buy today.
Ready to dive in?
Are pool alarms required by law?
According to SafeKids, almost 800 children drown each year, and half of those are under the age of 5.
For this reason, more and more states are requiring pool alarms on all residential swimming pools without automatic covers. Among those are Connecticut, New York, Tennessee and California.
In 2011, Tennessee passed their pool alarm law, called “Katie Beth’s Law,” after the tragic drowning of a state senator’s great-granddaughter, Katie Beth Burk.
The law requires that a pool alarm be installed on any pool and spa deeper than 36” and that it be able to sense any object 15 lbs. or larger falling into the water.

Pool owners are also required to post signs that read: “State Law Requires a Pool Alarm to Be Installed.” The law applies to all residential pools and hot tubs.
The type of alarm you ultimately purchase will really just depend on what your needs are.
Some pool-owners decide to invest in more than one, such as a gate and a wristband model for extra precaution.
There are a lot of different types to choose from and the comparisons can get confusing, but they all basically fall within three categories:
1. Pool entry
Pool entry alarms sound when someone or something enters the pool and fall into two categories themselves:
- Surface Sensor. These types float on the pool water and sense movement in the event that anything falls into the pool. A good surface wave sensor alarm can be adjusted for sensitivity so that it’s not being sounded every time a leaf falls in. Some can be adjusted, for example, when anything larger than 15 pounds disturbs the water, as required by Tennessee law.
- Sub-Surface. These types are activated by pressure changes below the surface caused by motion-activated waves. They are mounted to the wall under water and use magnetic sensors. In a study done by the U.S. Consumer Product Safety Commission (CPSC), these were found to be the most consistently reliable types of pool alarms.
- Pros: reliably detect motion in the water
- Cons: aren’t activated until a child or pet actually falls into the pool; more sensitive models can sound when light debris or wind moves the water
2. User-entry (wristband)
User-entry models are placed on a child’s wrist and locked with a key, and they sound when the child gets the wristband wet, sending you an audible alert when they’ve entered a body of water.
It’s important to know that in states where pool alarms are legally required, wristband models do not meet those requirements.
- Pros: can equip only those not allowed to enter the pool alone so that adults don’t accidentally set off the alarms; portable so you can protect your kids from dangerous water even while on vacation
- Cons: can cause false alarms since it sounds any time it gets wet; provides no warning if the child isn’t wearing it
3. Gate alarms
Pool gate alarms attach to the gates and typically use magnetic sensors to alert you when the gate is open.
- Pros: don’t have to be deactivated while swimming like surface and sub-surface alarms; alert you before someone is in the pool area, giving you more time to react
- Cons: if gate is accidentally left open, there’s no way to be alerted if someone enters; if a sneaky neighbor climbs the fence, you’ll probably never know
Features to look for
Since there are a variety of pool alarms available, there are a few different things you will need to consider when choosing one:
Would you rather have an alarm installed at your gate or at your pool or both?
If you install a gate model, you may be alerted before a child enters the pool area rather than after they’ve fallen in, however, if someone accidentally leaves it open, they’re still at risk.
You may instead choose a brand that will alert you when something falls in, but they can be more costly than gate units and cause some false alarms.
Another option is to install both a gate and a pool alarm. This could be a wise choice for your family if you have small children or pets you would like to keep safe.
If price is a factor you have to consider, often a gate alarm is the least expensive choice.
However, all options should be considered carefully to make the safest decision.
The quality of the sensors varies greatly and what you choose will depend on the type of technology you’d like to have.
For example, some types can be adjusted so that they only detect anything falling in that weighs over a certain amount, while others will sound with light debris.
The better the technology, the more control you will have over the sensor.
In case you still need help deciding, we’ve put together a list of our choices below.
