AliMed PIR Alarm Systems are simple, safe and dependable motion-detection technology to help manage patient care and fall prevention. The PIR Alarm works just like automatic motion-detection lights. When the beam is interrupted, the alarm is sounded.The PIR beam is narrow and fan-shaped so that only the bedside area is monitored. The alarm won't go off when staff members enter the room. These systems eliminate the hazards associated with cords tripping and accidental wire pulls are eliminated.System 3 AliMed Motion Detection Bed Alarm with Remote Receiver/Alarm Unit Ideal for facilities that are not with a nurse call station but still want remote notification of patients exiting their beds. It consists of the PIR Remote Alarm and a Remote Receiver/Alarm Unit that can be mounted outside a patient's room. The bedside alarm can be set to sound or remain silent. With either setting, it transmits a signal to the Remote Receiver/Alarm Unit, which sounds and flashes simultaneously, making it easy to identify the patient in need. The Remote Receiver/Alarm Unit can receive a signal up to 100' away from the PIR Alarm. System comes complete with all mounting materials and batteries. 1 Each / Each
