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.
