Data Port Protocol

alarm determine the voltage between these pins. The nurse call

polarity is set by using the procedures in the Start-up and Use

section. To access the nurse call menu from the main menu,

press softkeys SETUP, NEXT, NEXT and NCALL.

When the nurse call polarity setting is normally high (NORM +)

and there is no alarm condition, the voltage between pins 11 and

10 will be +5 to +12 volts DC. Whenever the monitor is in an

alarm condition, the output between pins 11 and 10 will be -5 to

-12 volts DC. When the setting is normally low (NORM -), the

readings are opposite, as indicated in Table 12.

These voltages are present only when the monitor is operating on

AC power.

If the audible alarm has been turned off, or silenced, the nurse

call alarm is also silenced.

Pins 7 and 15 provide a solid state relay that closes when an

alarm is sounding on the monitor. Pins 8 and 15 provide a solid

state relay that opens when an alarm is sounding. Pin 15 is a

common lead for both relays. The solid state relay operates

whether the monitor is operating on AC power or battery.
