One of our best selling Fall Safety products! Easy to set up and use. This wireless motion sensor with pager, allows the carer to receive the alert up to 300' (90 meters) from the motion sensor. So regardless where you are in the home or building, you will know that your patient is trying to get out of bed or moving about. The pager and motion sensor can be up to 300' apart (90 meters). When used to monitor a patient getting out of bed, the motion sensor is placed at floor level at the headboard end of the bed, facing down to the foot of the bed. When the patient put's their feet over the side of the bed and their feet are approximately 12 inches (30 cm) from the floor, the motion sensor picks up the movement, and sends a wireless signal to the pager, which is kept with the Carer. Can also be used across a doorway to monitor if someone is leaving a room, the house or a building. When the pager receives the signal, you have your choice of hearing a chime or a brief tune. The motion sensor that is in the room with patient is silent. This is a great way to monitor without disturbing everyone in the house or upsetting your patient with the alert noise. Batteries included.
