The Wireless Bed Alertamat is placed under a bed mattress, and will activate the alarm when a user leaves the bed so that the caregiver can ascertain their safety. When the user returns to bed, the alarm is reset.No wires mean this Alertamat is extra safe to use, and it is made from an antibacterial material which is easy to clean. It can be used with a nurse call system through the Alerta Wall Point Receiver for centralised activation or used alone, independent of nurse call systems, through the Alerta Wall Point Receiver only.
