An RS-232 Nurse Call signal (pins 5 and 11) can be obtained by connecting to the
data port. It is in the form of a positive or negative voltage chosen by the user.
The remote location will be signaled anytime there is an audible alarm. If the
audible alarm has been set to Off or silenced, the Nurse Call function is also
turned off.
Pin 11 on the data port is the RS-232 Nurse Call signal and pin 5 is ground
(Table 20). When there is no audible alarm, the voltage between pins 10 and 11
will be -5 VDC to -12 VDC, or +5V DC to +12 VDC, depending on the option
chosen via the softkeys (either NORM+ or NORM-). Whenever there is an
audible alarm, the output between pins 5 and 11 will reverse polarity.
An internal Nurse Call relay (pins 7, 8, and 15) provides dry contacts that can be
used to signal a remote alarm. Pin 15 is common, pin 7 is normally open (N.O.),
and pin 8 is normally closed (N.C.). Table 20 shows the state of the contacts for
