Multi-Station Patient Room Applications
1. Four bed application covered by four NH-1SA/A sub stations
with a common bathroom pullcord
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.
