Incidents of unwanted drowning are very common if you do have children and pets in your house. Adult supervision can prevent these accidents to some extent, but pool alarms are the best option to do this job. And, it is worthy to mention that many states’ law does require a pool alarm in your pool.

In this article, I will try to guide to through the pool security systems. When you are done reading this, you will get a clear picture of the necessity of pool alarms and facts related to it. Besides, I will present some pool alarm reviews to help you find the best product for your pool safety.

Why is a pool alarm a necessity?

Why is a pool alarm a necessityIf you have some kind of swimming pool or spa in your lawn or backyard and you also have kids or pets, then you may be on a constant tension. Well! Pool alarm can be the best investments for you to ease down that stress. A pool alarm can watch over your pool to restrain any unwanted accidents. It can indeed reduce the risk of accidental drowning in your backyard. Your babies, young children, pets and non-swimmers of all ages can wander or play in the lawn without bothering you about their safety.

Pool alarm nowadays is not just another trend, but it is a mere necessity. If you haven’t set a pool alarm yet, here are a heap of reasons that you must get one today to protect the family and others.

Protection of kids

Children are very curious by nature, and definitely, water is the center of attraction to them! Besides, Children and water pools just sync together. A staggering number of 700 children in the United States die each year due to unintentional drowning. For every kid who drowns, five more need to rush to the emergency room for non-fatal submersion injuries. The even more disturbing part of the statistics is that each of these accidents was completely avoidable. So, it is no wonder that most of the pool alarm buyers put it in their carts to protect their children.

If you have a neighborhood with lots of children, then it’s the best way to protect the wandering children from drowning in your pool. Who doesn’t know that children can’t usually resist the urge to play in the pool? And, you probably don’t want your pool to be the center of that accident.

Protection of pets

Like kids, your pets such as dogs, cats or other animals are also very susceptible to pool accidents. In order to protect your lightweight pets, it’s always a good idea to bring a pool alarm to home.

Legal obligations

Pool alarm in nowadays is more than a necessity. In many parts of US is a must to have a pool alarm and a pool gate alarm. A pool safety law in those states and cities requires its homeowners to maintain a pool alarm and a pool gate alarm in their pools.

A pool gate alarm is also a safety barrier that alerts the homeowner if someone opens the entrance of the pool area. Besides, it can give you the opportunity to intervene before anyone gets near the water.

To know more about the legal obligations regarding pool alarm in your community, you should check with your municipality. You may need a pool alarm, a pool door or gate alarm, a pool fence, or all of the above.

Pool alarm regulations

Often tragic local drowning in all kinds of pools or bodies of water prompts the authority to make new pool and spa alarm laws, regulating residential pools. According to the rules, the alarms must have the following features:

  • The pool safety system has to operate 24/7
  • It should detect the fall of a child of 6 kilos
  • The alarm must be child tamper proof
  • It has to have an immune system to atmospheric conditions
  • The alarm must include a signal system which will show that it is working satisfactorily

How do pool alarms work?

To create a safe swimming pool environment for the whole family, the pool alarm systems are the ultimate option. They will act as the last line of defense against any unwanted drowning.  Besides, it can add some extra safety to your swimming pool and pool area.

The pool safety systems have an attachment that extends 8 to 10 inches under the surface of the pool water. It acts as a motion detector. You need to place the wireless pool alarm on the deck of the pool about halfway from each end of the pool. Now, if anything around the designated weight 20 lbs, enters the pool the detector will sound an audible alarm.

Many alarms have a two-way remote that signals an audible alert via the remote if anything triggers it. The remote can also set off the actual alarm by itself. It works remotely. The whole system is wireless, and it only needs batteries to function.

Types of pool alarms

There are many options that you can easily get confused while purchasing a pool alarm. You can use any of them to keep your pool secure. But, at first, you need to know their mechanism and what they offer to safeguard your pool area.

I will discuss various pool alarms and their features underneath to help my readers to find the perfect safety system for their pool.

  • Surface alarms
  • Subsurface alarms
  • Perimeter alarms
  • Personal immersion alarms
  • Wearable alarms

1. Surface alarms

A surface pool alarm is a kind of a safety system for your pool that floats on the surface of your pool. To keep them in the center of the pool you need to tie them to twine or string.


A type of tilt alarm operates with the surface alarm. It is something like the old pinball game. You will find a vertically hanging metal rod that is suspended inside the 1.5 inches sensor ring. Whenever the rod touches the ring, the alarm will go off. Surface alarms can detect the surface disruption through the surface waves. When an object falls into the pool, the surface waves trigger the alarm.


You can use the surface alarm in the pools that don’t have any hard edge. In addition, it can be used in the ponds or in the fountains.


Surface alarms have some benefits to convince you to use it for in your pool.

  • This alarm is very easy to set up
  • It doesn’t require any installation
  • Battery powered (9V or AAs)
  • Helpful for protecting small pets
  • Usable in spas and in-ground pools


Surface alarms also have some disadvantages that you should know about.

  • Some model can produce a false alarm because of wind and heavy rain or falling leaves, branches and objects

2. Subsurface alarms

Subsurface alarms can detect any movement underneath the surface of your pool water. They are also known as the ‘Subsurface wave detection system.’


The subsurface alarms contain a below-water sensor. The wave-induced pressure changes in the water activate the alarm. There are two designs of this kind of alarms. One counts on the movement of a magnetic float below the magnetic sensor. And, the other depends on the pressure-sensitive switch.


The subsurface alarms can provide the best options for small aboveground pools or the soft-sided pools, small ponds or fountains.


The benefits of the subsurface alarms are like:

  • Less false alarms
  • No need to remove during swimming
  • Has adjustable sensitivity features
  • Works in in-ground pools and spas
  • Usable with a solar cover


The disadvantages of this safety system are like:

  • Many models need installation onto the side of the pool, which makes it difficult for soft-sided above ground pools

3. Perimeter alarms

Perimeter alarms are different from the normal pool alarms. It features infrared alarms.


The perimeter infrared alarm uses the invisible laser beams to detect the movement.  It encircles the pool or the pool area. Anyone crossing the laser beam will set off the alarm. The siren will alert the homeowner to avoid any unwanted incident.


You can use the perimeter alarms for any kind of water pools.


This type of safety systems are the expensive ones in the market with a lot of benefits.

  • Can give you total protection on at a set height.
  • Laser beams are adjustable.


Perimeter alarms have some disadvantages as well.

  • Very costly.
  • May not suit the visiting children as you need to set the height according to your child
  • The siren will go off if the pool’s perimeter alarms are unintentionally moved, hit, or covered

4. Personal immersion alarms

Personal immersion alarms work through a special wristband or a pet collar. A person or the pet has to wear these bands or collars. If anyone wearing those bands or collars falls into the water, it will activate the alarm, and that will sound a remote alarm.


You need to fasten the wristband or the collar securely on the wrist or around the animal’s neck. The band or the collar has a battery-powered sensor. The main alarm alert is on a separate base station. If the sensor immerses in water, it will trigger the alarm.


This type of wearable pool alarms is usually for children and pets.


The benefits of the Personal immersion alarms are many. Such as:

  • It provides continuous protection
  • Triggers the alarm immediately after the immersion in water
  • Don’t need any set-up or installation
  • Portables
  • Usable in all kind of water bodies


The personal immersion alarms also have a disadvantage like:

  • False alarm can occur with the daily activities like washing hands or walking in the rain
  • The pets or the children need to wear the collar or band. Otherwise, it won’t work

5. Wearable alarms

Wearable pool alarms are just like the personal immersion alarms, and it works exactly like that.

What to consider before getting a pool alarm?

As I have stated already that many states have made it mandatory for their residents to install pool alarms in their pools. In the other states, the local authority or the municipality may require you to install pool alarms, but not the state itself.

Make sure to go through your local code enforcement department before buying that you’re in compliance with the laws and rules where you live.

Regulations of use

States like California, Connecticut, Tennessee, and New York have pool safety alarm laws on the books. Let’s have a look what the regulations of these states say about pool alarms.


California has always acted as a leader in propositions, and their pool laws are way ahead of the curve. It’s because of both the safety and energy.

Standard features

Pool alarms are of various shapes and sizes, and these convey notable highlights or features too. The most fundamental features incorporate a disable button and the alternative to change the sensor’s affectability. Some pool alarms can also turn off consequently as they are lifted out of your pool. Many alarms have advanced features that may increase the sensitivity of the alarm after displacing or lifting it from the pool’s surface.

Number Of alarms

Look for the products that have two alarms. Because of the two alarms, it will be easier for you to hear the siren and rush to the pool area before any bad things happen.


Pool alarms have various sensor technologies. In the gate alarms, there are magnetic sensors which will go off as the gate is opened. In-ground pool alarms are designed to detect the movement of the water. Whenever the sensors detect any movement or disturbance in the water, it will trigger the alarm. In some products, the alarm may go off with the amount of weight displacement.

Pool alarms are there to help you get children, pets, and trespassers away from your pool. To get the maximum benefit, you should go for the products that will suit your pool. Besides, you can go through some pool alarm reviews to find which product will be the best for you according to your specific requirement.


You must find an alarm that you can hear when the sound of the siren is coming from far. Because of this, you should go for a loud device. However, you should be careful to choose a model that shouldn’t be too loud that may irritate you.


The pool safety systems that have two alarms, they usually come with a receiver. The receiver works within a particular range. Make sure that your product will offer the perfect range- depending on the distance of your house and pool.


The price may vary from one model to the other or one brand to the other. Take enough time to go through different models and brands to find out the features and the price. It will definitely give you the best one of your need while not breaking your budget.
