How To Choose The Right Pool Alarm?

Here are a few things you should consider to ensure you choose the best pool alarm.

  1. Alarm volume: Choose an alarm that you can hear easily when it goes off, thus make sure your alarm is loud enough. However, don’t get an alarm that is too loud and disturbs your neighbors.
  1. Types of alarm: Each type of alarm has different setup modes. Some are good for in-ground pools, while some are perfect for above-ground pools. Choose a model that is perfect for your pool and fulfills your needs. These are the three major types of pool alarms:
  • The first type of alarm is to be placed around the pool. The alarm is triggered when the surrounding space is entered, just like how a regular security alarm works if there is a break-in. This ensures your kid or pet does not enter the premises without your supervision and keeps away any intruders.
  • The second type is meant to be installed inside the pool. This pool alarm works by sensing any disturbance in the water, such as the splash of your kid or pet who has fallen inside.
  • The third type is an ideal option for kids, and it is a wearable pool alarm. It can be worn as a bracelet on your kid, and the alarm goes off the second it touches water.
  1. Quality: Choosing a pool security alarm from a trustworthy brand will ensure no technical issues in times of danger.
  1. Price: The price and features differ for each brand and model. Shortlist the ones in your budget and those that provide the necessary features.
