The Pool Patrol Model PA-30 is the deluxe model with an electronic solid state remote receiver. An alarm will sound both in your pool and in your house up to a distance of approximately 200 feet. The FCC-approved remote receiver has an on/off switch with an "on" indicator light and is powered by a 120 volt A.C. wall transformer. The Pool Patrol PA-30 floats on the pool surface and will activate when children or pets fall into the pool, creating a wave. When the wave touches the sensing ring of the pool alarm, the alarm is triggered, emitting a clear warning signal at the pool as well as on the remote receiver. The sensing ring is adjustable so that it can be controlled to activate only when an object the size of a child or pet falls into your pool. The Pool Patrol will add an extra margin of safety to your swimming pool. It is easy to set up, convenient to use, and designed for many years of use. It is a must for every pool owner concerned with pool safety. The PA-30 is easy to install and convenient to use. It is corrosion-resistant for long life. Ideal for both in-ground and above-ground pools. Also protects commercial pools and spas. The alarm comes complete with all the necessary mounting hardware. Made with pride in the U.S.A.
