The Poolguard Door Alarm DAPT–2 mounts next to any door which gives easy access to your swimming pool. Any door which allows young children easy and quick access to a pool area is dangerous and should have a door alarm. The Poolguard Door Alarm comes with two magnetic switches, hook–up wire and operates on one 9– volt battery. The door alarm has a delay switch which allows an adult to pass-through the door without the alarm sounding.
