CBN-11 is a Cancel/Presence switch usually installed by the door of the patients’ room.
It can cancel the Nurse Calls activated from the Patient’s handset (PB-03/04), Pull Cord Switch (TB12) or Patient Console Switches ( PBCN-13 & PBC-12).
The nurse will use CBN-11 after a call has been taken care of and there is no more activated call associated with the room.
