"More than 900 children between 1 and 14 die each year in drowning accidents. In California, drowning is the number one cause of accidental death for children 1-4 years of age. But, do you really need these statistics to convince you to do everything you can to prevent this from happening to your child or grandchild? The Safety Technology POOL ALARM is an electronic monitoring system that automatically sounds an alarm when children or pets fall into your unsupervised pool. It's portable, self-contained and light weight. The unit is simple to operate. Entry into the pool will be detected by the Pool Alarm's electronic sensor, triggering a loud pulsating alarm at the unit and inside your house from the remote receiver. The Pool Alarm installation is very easy. It sits on the pool deck as shown in the picture. It is very easy to use with control button operation and will automatically arm the unit once you are done swimming.
