Nurse Call Setting Connections
For maximum flexibility, either normally open or normally closed signals are available. During
an alarm condition or a low Signal IQ event, depending on the configuration of the device
output, the normally open pin will be connected to the common pin and the normally closed
pin will be disconnected. In addition, the Nurse Call Polarity can be inverted to accommodate
various nurse call station requirements.
Only qualified personnel should connect one of these two signals to a hospital’s Nurse Call
system.
