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 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. After you install the Pool Alarm, it can't be deactivated; it is always in the alarm ready mode until you put it in Sleep Mode. If someone who does not know how to put the Pool Alarm in sleep mode attempts to remove the alarm, it will sound an alarm. The Pool Alarm comes with a remote receiver which can be mounted in your home up to 200 feet from the main unit. It comes with a 12 volt power supply. The Pool Alarm uses one 9-volt battery (not included) which should last approximately one year. There is an audible low battery indicator which will sound at the poolside alarm and the remote receiver.
