Buyer’s Guide

Now for some information about how the different models work and what to consider when evaluating pool alarms.

Type

Surface Wave Detection

Floating pool alarms are suitable for in-ground or above-ground pools and spas. They detect when something has entered the pool by measuring water disturbance. They incorporate an electric circuit using two contacts – one in the water and one above. The circuit is complete and triggers the alarm once the device is touched by water from a surface wave.

A good thing about these models is that they require no installation and are easy to operate. You can remove them while using the pool then pop them back in afterward. They’re also sensitive to low weights, perfect for your lightweight pets. However, some can be sensitive to debris or strong winds and potentially trigger false alarms.

Subsurface Wave Detection

These alarms have sensors that will sound if there is water movement at the subsurface level. Their sensors are below the water and are triggered when the pressure changes. There are two types: one depends on the movement of a magnetic-floating device, and the other uses a pressure switch.

Best suited to in-ground pools and spas, they’re typically more expensive but are recommended as a more permanent solution offering the best protection.

Personal Immersion

These types comprise a base station and bracelet. Once the bracelet comes into contact with water, the alarm is triggered. Child wristbands include a lock to prevent removal. This system is portable and works with any pool, and you can even take them to the beach. However, the alarm could be activated if it gets wet during activities like walking in the rain.

Door and Gate Alarms

Once someone opens the door or gate of the area leading up to the pool, the alarm is triggered. This method allows you extra time to intervene before the child or pet enters the water. These alarms are typically installed at a height out of the reach of children and can be momentarily disabled.

Depending on your municipality, there may be requirements about the type of alarm you can install.

Placement

Surface Wave Detection

Floating alarms can be mounted on the edge of the pool or in the pool itself and then secured in place by attaching it to the side of the pool. Once the device detects water displacement, it sends a signal to the receiver to sound the alarm.

The receiver is best placed next to a window or opposite the pool and within 200 feet of the transmitter. The receiver should not be placed in cabinets, near steel walls, or close to electrical appliances like a computer. The signal reception could be disturbed if placed on a metal surface.

Sub-Surface Detection

Surface wave detection alarms are typically mounted to the most central position of the pool’s deck, on the middle section of the longest wall, for example – not too close to the return line and within at least five inches of the pool wall. The receiver is typically situated inside your home close to a power supply.

Some alarms require disabling and re-enabling via remote control or by inputting a code. Once the device is installed, its position is permanent. These types are suited to in-ground pools since the device needs to be installed on the side of the pool wall, which is difficult to achieve with above-ground pools.

Personal Immersion

The wristband or pet collar is a battery-powered sensor. Placed on your child’s wrist or a pet’s collar, it goes off once submerged in water. The receiver is situated inside your home. There is no installation or setup required.

Door or Gate Alarms

These are typically installed on the door or gate of your pool area and can also be attached to windows. By placing one part of the proximity sensor on the door frame and the other on the door, gate, or window, the alarm will be triggered once the sensors separate.

The Volume

The alarm volume is the most essential feature as it needs to be audible from every part of your home.

We measure sound in decibels (dB). A typical conversation is about 60 dB, a running motorcycle engine is about 95 dB. Above 120 dB is considered a very loud noise. Once the base unit/receiver of the pool alarm is triggered, it usually ranges from 85 dB to 120 dB.

Noise above 70 dB for a prolonged period could damage your ears, however. Most alarms will sound until disarmed or automatically turn off after a set amount of time – typically three minutes.

Ease of Use

When thinking about ease of use, consider the following:

  • Can it be used straight out of the box, or are you required to purchase an additional kit?
  • How easy is the installation process?
  • Can it be installed without any potential damage to your pool or its enclosure?
  • How easy is it to operate?
  • How easy is it to configure and adjust the settings?
  • How easy is it to disable the alarm once triggered?

The Range

The range is the maximum distance at which the sensor can communicate with the base/receiver to sound the alarm. If the sensors are not within range of the receiver, the alarm will not sound.

It also refers to the distance the alarm sound travels from the alarm. This metric is crucial. If the alarm can’t be heard from any point in your home, it’s pointless. Luckily, the sound measured for most pool alarms is 85 dB, which is sufficient to reach every corner of large houses.

Since the receiver only works within a specific distance of the sensor, you’ll need to consider the distance between your house and the pool when deciding on a suitable model.

FAQ

Are Pool Alarms Required by Law?

Most cities and states have pool safety laws that require pool owners to have a pool alarm and/or pool gate alarm to prevent accidental death by drowning. As each state is different, you’ll need to check with your city to determine what type of alarm is required, a poolside alarm, a pool enclosure, an alarmed pool door or gate, or all of the above.

How Much Does a Pool Alarm Cost?

The price of pool alarms varies depending on the type. However, you can expect to pay between $50-$500. The least expensive models are gate-mounted models, and the most expensive are in-pool motion detection systems.

Do Pool Alarms Really Work?

Pool alarms effectively let you know as soon as someone or something has entered your pool or pool area. Like fire alarms, they should be tested every so often, and most types are designed to let you know when the battery needs replacing.

Sometimes alarms can be triggered by a strong wind or a foreign object. For this reason, most pool alarms allow for sensitivity adjustments to help prevent false alarms.

Under no circumstance should a pool alarm replace constant supervision. Other pool safety options include having readily accessible lifebuoys, keeping your pool covered when not in use, and teaching your children about pool safety rules, e.g., never run around the pool area, etc.

Investment in Pool Safety With a Pool Alarm

A pool alarm is another excellent investment that any pool, spa, or pond owner can make. They act as a second layer of protection in reducing the risk to children and pets or non-swimmers from accidentally drowning. They should not replace supervision, fences, gates, pool covers, and locks, however.

There are plenty of choices available – from alarms that monitor the surface and subsurface motion to unexpected entry to the pool enclosure. One should consider their pool type, the home setup, and budget when deciding on the proper alarm to meet their safety requirements.
