Passive infrared alarm systems are simple, safe and dependable motion detection to help manage patient care and falls prevention. There are no sensor pads, pull-cord or clips to cause any false alarms. Used at the bedside, the alarm alerts the carer that the patient is trying to get out of bed. Detects the slightest movement of a hand, foot or head that crosses through the infrared beam. The alarm unit conveniently mounts to the bed rail and emits a fan shaped beam that runs parallel to the bedside. The over bed model is ideal for the highest risk patients; it may be mounted to a wall or headboard.
