This panel is installed at main nurse station /room. This panel indicates the room no / bed no from where patient needs some help. This panel also has optional LCD display to show the patient call.  Whenever any patient press the bed switch, a Nurse call LED for corresponding room/bed will indicate a call by the patient and a siren will alarm the nurse to get the attention. Nurse can mute the siren by pressing the ACK S/W switch but indicator will be reset only from the bed switch, which has been located near the calling patient's bed, ensuring that nurse visited the patient. If nurse wants to call service boy or doctor then she can use the corresponding button provided in bed switch module.
