6 Best Swimming Pool Alarms 2025 in the United States

The Poolguard PGRM-2 In-Ground Pool Alarm is a reliable option for ensuring pool safety. It’s NSF Certified to meet ASTM Standard F2208, indicating that it meets stringent safety requirements. This alarm is designed to detect intrusions similar to a one-year-old child, which suggests high sensitivity to small disturbances in the water. It’s suitable for pools up to 800 square feet or 20 x 40 feet in size. Being battery-powered, it’s easy to install without worrying about wiring.

The alarm is quite loud, with an 85-decibel horn that can be heard up to 10 feet away, and it comes with a remote receiver that works up to 200 feet, allowing flexibility in monitoring from inside the house. One notable feature is its tamper-proof design, which will sound an alarm if removed from the pool, adding an extra layer of security. The automatic wake-up feature ensures the alarm is always ready, performing system tests when installed. However, it requires a 9V battery, which may need regular replacement.

The dimensions (14.5 x 4 x 12.75 inches) and weight (5 pounds) make it relatively bulky, which could be a consideration for some users. Made in the USA, it comes with a 3-year warranty, offering peace of mind regarding its durability and support.

The Poolguard In-Ground Pool Alarm is a battery-powered safety device designed to alert you when someone enters your pool area. It uses advanced Negative Displacement Technology, which is sensitive enough to detect children, pets, or even intruders by sensing disturbances in the water. One handy feature is its remote receiver that sounds an alert inside your home, so you don’t have to be outdoors to know if the alarm is triggered.

Installation is easy since the alarm is portable and doesn’t require complicated wiring, tie-downs, or ropes. It’s designed for pools up to 20 feet by 40 feet, and it works well even if you use a solar blanket on your pool, adding extra versatility. The alarm emits a loud pulsating sound, which is effective for drawing attention quickly.

The alarm is tabletop-mounted, meaning it’s not permanently fixed, which might affect stability in windy conditions or if bumped. Also, since it runs on batteries, you’ll need to ensure they are checked and replaced regularly to maintain protection. While it isn’t the cheapest option on the market, it has received high customer ratings for reliability and ease of use. This alarm is a solid choice for families looking for a straightforward, portable pool safety alert that keeps you informed both outside and inside the home.

The Techko S187D Safe Pool Alarm is designed to help keep children safe around pools by alerting you if a door or window to the pool area is opened. It uses a contact sensor type alarm, which means it detects when a door or window is opened, triggering a loud 110-115 dB alarm with six different tones. This volume level is quite strong and should be loud enough to get attention quickly. The alarm is battery powered, using one 9V alkaline battery, which lasts about 2160 hours, but note the battery is not included. Installation is straightforward with adhesives and placers to mount it on door frames or walls, keeping it out of reach of children. It also has a useful patented screen door sensor that allows you to keep sliding glass doors open without setting off the alarm, though this secondary sensor doesn’t work separately and needs to be paired with the main alarm unit.

The alarm meets key safety standards like UL 2017 and complies with the Child Pool Safety Law, which is important if you want to pass pool inspections. It’s weather-resistant with an IP65 waterproof rating, so it can handle outdoor exposure. A handy low battery indicator shows a red LED light when the battery needs changing. One minor downside is that the alarm only temporarily disables for 10 seconds via two bypass buttons, which might be short if you frequently enter and exit the pool area. Also, since the secondary sensor is not a standalone alarm, you might need multiple units for multiple doors. This alarm represents a reliable choice for parents or pool owners who want a simple, effective way to monitor pool entry points and comply with safety laws.
