Multi-Station Patient Room Applications

Multiple NH-1SA/A and NH-2SA/A bedside sub stations can also be installed within a patient room. Observe the following conditions;

•Max. 6 bedside sub stations may be connected per room for max. 12 calls (when NH-2SA/A stations are used).

•A corridor lamp inside (NHR-4A) must not be connected with more than 4 bedside sub stations.

•Due to the above, install two NHR-4A corridor lamps when more than 4 sub stations are in one room, i.e. two WHITE lamps used in one NHR-4A, and one RED bulb used in the other NHR-4A.

•NH-1SA/A and NH-2SA/A station numbers must be programmed in numerical order and connected to the same subs trunk line.

•NHR-7A bathroom pullcord is optional.

(*2) NHR-7A may be wired to any sub station convenient. Terminal RL is wired only on the sub station which NHR-7A is connected to.

The above example shows a patient room with four beds, in which a common bathroom pullcord is used. Multiple sub applications can be arranged in the following manner.

Beds in Room	Subs combinations	Beds in Room	Subs combinations
2	One NH-2SA/A or two NH-1SA/A	7	Three NH-2SA/A & one NH-1SA/A
3	One each NH-2SA/A & NH-1SA/A	8	Four NH-2SA/A
	or three NH-1SA/A	9	Four NH-2SA/A & one NH-1SA/A

6	Three NH-2SA/A	12	Six NH-2SA/A

Note; Bedside sub station Models: NH-1SA and NH-2SA CANNOT be used in multiple bed patient rooms.
