With the Wireless Call Monitor you can monitor a patient using a bed sensor pad. The monitor can alarm at the bedside or it can be silenced and the signal goes to a pager carried by the caregiver (clipped to a belt or inside a pocket). This allows the caregiver to be notified wherever they are without disturbing residents. There is also a Call Button located on the front of the monitor that allows the resident to call the call the caregiver. Wireless Call Monitor operates on 1 -9v battery. Pager operates on 2 AA batteries. Batteries not included.
