For use with the Fall Savers Standard Monitor only (sold separately). The alarm sounds when a wandering or fall risk user steps on to it. The floor sensor pad is placed on the floor next to the patient's bed or chair so that the user steps directly on the sensor when exiting the bed or chair. Once the user's weight is placed on the floor sensor, the monitor will sound an alarm. Approximate dimensions: width 785 x height 395mm (31 x 15.5 inches).
