What Is a Pool Alarm?
A pool alarm is a system designed to alert pool owners that an animal or child has fallen into their pool. There are several different types of pool alarms available, and they all work to make sure that adults are alerted to a situation with enough time to save a life. Even if you don’t have your own children, keeping an alarm on to save neighborhood kids is just as important.

How Do Pool Alarms Work?
Although there are several types of pool alarms, most of them will work by picking up a change in the surface tension of the water. If there are waves or the pool water splashes above the sensor line on an alarm, it will sound. The alarm itself will sound, and then there is usually an additional sensor inside the home that will also sound.
Local Pool Alarm Laws
Depending on where you live, there are likely going to be local pool alarm laws. The laws will differ by state and sometimes the county. It is very common to have door and window alarms on your house if you install a pool. You will also have to have a fence around your pool in many areas. This fence may also require an alarm on it.
When you put a pool in, you will have to pass inspection, so your pool will need the best pool alarms on the market. However, if you are purchasing a home that is new to you, you should do some research as to the alarm type that you may need.
Types of Pool Alarms
There are four basic types of pool guard pool alarms. Depending on your current situation and who you are trying to protect from injury, death, or drowning, make sure you choose your alarm carefully.
Threshold Pool Alarms
A threshold alarm allows pool owners to be notified if the pool area has been breached. The threshold pool alarms consist of gate alarms, door alarms, and window alarms. The great thing about the threshold pool alarms is that they also work as a general security measure for your family.
Pool Alarms With Surface Wave Sensors
The surface wave sensors will be able to tell if the water has moved because of something falling in. Most of the time, these pool alarms are going to be floating pool alarms. As the water level moves, the alarm will sound. Most of the time, the alarm will sound with a 15 pound or more object falling into the pool.
Pool Alarms With Subsurface Disturbance Sensors
A subsurface disturbance sensor will let you know if there was a wave moving across under the water’s surface. This is a great choice for rainy or windy climates that get many false alarms from the Surface Wave Sensors. Again, the waves that this picks up on will be created by a 15-18 pound object changing the water.
Wristband Alarms for Swimmers
Lastly, you have the wristband pool alarms. These are worn around the wrist of kids or even a pet to make sure that an adult is alerted as soon as they go in the water. Although these wristband options are highly effective, you have to get your child and pet accustomed to wearing something like this.
Why You Need a Pool Alarm
A pool alarm will save lives. Aside from it sometimes being the county or state law, pool alarms are something that you will never regret investing in. Many good children know not to enter the pool without a parent present. However, the majority of drowning accidents happen when someone falls in the pool.
Falling around the pool’s edge is quite common, and very often, people experience a head injury on their way into the pool. Pool alarms are not going to change your pool’s aesthetics and are not all that expensive. Every pool should have one.
Considerations for Finding the Best Pool Alarm
When choosing a pool alarm, there are a few considerations that you must keep in mind.
Type
You would be surprised how many people own pool alarms and still don’t use them. Choose an alarm that you are going to use, and that will keep your pets and children safe. If you don’t like the floating pool alarm look, choose something that is a little less visible. If you don’t think the at-risk members of your family will wear the wrist bands, choose a different type. Purchase something that works for your type of pool and for your preferences as well. Promise yourself that you will actually use it.
Sound
The best pool alarms are those that will sound both inside and outside. If your child happens to escape the house, but you are still inside, you will need to be notified. The same goes for if you are sitting on the patio, not paying attention to what is going on in the swimming pool.
False Alarm
Some pool alarms are known for having false alarms. The false alarms happen when a ball enters the pool, or a leaf falls on the surface. This can get very frustrating, and people will be tempted to turn the alarm off. The problem with this is that as soon as the alarm is off, the pool is not adequately protected. We highly recommend looking for something that has a low tolerance for false alarms. Don’t purchase something that will alarm each time it drizzles or a gust of wind crosses over the pool.
Price
The prices of pool alarms run from around $50 to well over $200. The price is not quite as important as the ability to detect water disturbances. If you find a great deal on a pool alarm and it works effectively, it is certainly worth considering.
