Pool alarms can offer pool owners another barrier of pool protection. Pool alarms work well in conjunction with other safety features including other barriers including fencing, appropriate safety covers and closely watching all those in and near your pool.
Pool alarms inform through audio signals when someone enters the pool and are each sold with different decibel capabilities. They specify whether they are for above or inground pools and are designed to cover a specific pool's surface size or area of space.
Pool surface alarms work by distinguishing and signaling when someone (or a certain weight) enters the water's surface. Most go off around the pool and many have another external component that can be plugged in somewhere in your house as well. Some float while others attach to the pool's rim or ladder. There are also underwater or subsurface pool alarms that distinguish and signal when there is underwater movement.
Wristband alarms are a great safety innovation for children. An audio alarm sounds when the band is in the water. This means that the alarm will be ineffective if the child for any reason is not wearing the wristband. Most of these systems have tamperproof locks to ensure the band stays on a child. This type of alarm has the ability to function when there are already swimmers in the pool, unlike the wave-recognition alarm systems.
Infrared detection systems tend to be more expensive alarm options but nevertheless practical. An infrared alarm has an invisible laser beam that encircles your pool or yard. Once someone walks through the laser beam, the alarm activates, catching the child or even a would-be burglar before they enter the pool or taking your belongings.
Some pool systems combine two of the above alarm functions in one product. There is currently an alarm system that detects both ground movement using infrared beams and is signaled by pool waves using an underwater alarm.
Gate alarms are another way to protect anyone from entering into your pool's area. These types of alarms are put on a gate and signal when it is opened. Most work all the time and allow adults to go through by entering a password on a keypad.
An alarm only works as well as it is maintained and it is wise to monitor batteries, take good care of the system and do sound checks to ensure it is working properly. Many come with noise alerts when the battery is low, and others are weather and water resistant, which is important.
Also, remember that different alarms take different amounts of time to activate and some go off immediately while others take longer. This is very important as time is essential when someone falls into water.
The price of a pool alarm averages between $100 and $250.
